A chemical solution used to remove a layer of base metal to prepare a surface for coating or binding.

The process of selectively removing any material not protected by a resist using an appropriate solvent or acid. In some cases the unwanted material is removed using an electrolytic process.

See "Chemical Etching."

Decorative process of engraving the top (colored) layer of a piece of flashed glass with a rotating tool in order to let the clear layer appear.

Scratching or roughening an existing wallpaper surface to prepare it for the application of a wallpaper-removing solution. The etching of the vinyl-coated surface allows the solution to penetrate through the wallpaper and dissolve the old adhesive to aid in the removal of the existing wallpaper.

This technique involves using acid to bite grooves into the plate. A substance called an etching ground blocks the acid from biting through in certain places, while disruptions in the ground allow the acid to bite in other areas. The plate is printed by pressing ink into the grooves and wiping excess ink off the surface. Ink is then transferred from the plate to the paper by being run through a press.

an intaglio printing technique that yields prints which are characterized by their freedom and vitality, as opposed to the relative stiffness of engraved prints. a fine-pointed tool called an etching needle is used to draw the image on a metal plate coated with a waxy layer. this surface is much easier to draw on, and allows the artist to create fluid, expressive lines. the plate is then placed in acid, and the lines that have been etched are incised ("bitten") by the acid. the coating is then removed so the plate can be inked, covered with a piece of damp paper, and run through a press, which forces the paper into the incised lines to pick up the ink and absorb the image.

The chemical removal of metal, usually by an acid or chloride

A technique similar to engraving, except that the etching plate is not as durable as the engraving plate, thus limiting the edition size of a particular print.

A sketch formation in glass, brass, stainless steel, etc., caused by a chemical reaction of acids.

An intaglio method in which the lines are bitten by acid. The plate is coated with an acid-resistant material ( ground) through which the artist draws lines that expose the metal. The plate is immersed in acid until the lines are bitten into the plate. The ground is removed before the plate is inked for printing. See ground.

Treatment of a surface with an acid, a chemical solution or primer in order to dissolve loose particles or provide a profile.

The act of removing selected material from a substrate, either using chemical agents or beams of focused energy.

An intaglio printing process in which various etching needle s are used to draw into a wax ground applied over a metal plate. The plate is then submerged in a series of acid baths, each biting into the metal surface only where unprotected by the ground. The ground is then removed and ink is forced into the etched grooves. When the plate surface is wiped clean only the ink from the grooves are applied to the paper during printing. Etching is sometimes confused with engraving.

Etchings are usually made from a copper plate dipped in an acid bath. Before this, however, the plate must be prepared with a ground, (wax and bitumen) that is then made black by being held over candles. This makes the copper lines gleam as they are drawn across the plate with an etching needle. Then the back of the plate is coated with a stopper varnish to prevent it from dissolving away, and the plate is put into the acid. Additional drawings may be made to further complete the print, and other areas already worked over, coated with stopper, as more depth and thickness is achieved with further baths in the acid. Any prints pulled through the press at this point will be the first, second, etc pulls or proofs, and have greater rarity than those pulled when the print is finished.

An intaglio printmaking process in which a metal plate is first coated with acid-resistant wax, then scratched to expose the metal to the bite of nitric acid where lines are desired. Also, the resulting print.

A metal plate is coated with a varnish-like substance (known as the "ground") that is impervious to acid. The artist creates an image by drawing through the ground with an etching needle, thus exposing areas of metal. The whole plate is then immersed in acid until the exposed lines are sufficiently bitten, producing grooves in the metal that will hold the ink. The ground is then removed, and the plate is ready to be inked and printed.

A means by which lines are created in a metal plate with acid for printing by the intaglio technique. First, the plate is first covered with an acid-resistant material. Then, the artist scratches a design on it with a stylus or needle to expose the bare metal underneath. The plate is then immersed in an acid bath. The acid attacks the exposed metal to engrave the lines in the plate. See also INTAGLIO PROCESS PRINTING PLATE

Corrosion of pool's surface by water that is acidic or low in total alkalinity and/or calcium hardness.

(n) The method of creating patterns, typically in metal, using chemical processes. In the electronics industry, etching is used to remove conductive material, usually copper, from printed circuit boards to create wiring patterns. The wiring pattern is printed on the board in a chemically resistant ink, and the rest of the conductive material is then dissolved away in a chemical bath.

A process similar to engraving in which acid is used to etch a design into the surface of metal, glass or gemstones.

removal of material from a substrate, usually with potassium hydroxide (wet etching,) or with a stream of gas or plasma particles (dry etching)

An intaglio technique whereby marks are bitten into the metal plate by chemical action. The plate is coated with a ground (either hard or softground) impervious to acid through which the artist draws to expose the metal. The plate is then immersed in an acid bath until the open lines of areas are sufficiently bitten. Finally, the ground is removed and the plate inked and printed. Etching is commonly used in combination with drypoint, aquatint, and other intaglio processes.

A means of incising lines in a metal plate with acid for printing in the intaglio technique. The plate is first covered with an acid resistant ground through which the artist scratches a design with a stylus or needle, revealing the bare metal below. This plate is then immersed in an acid bath that cuts the incised lines into the plate. Etched lines often betray the subtle motions of the artist's fingertips.

As with engraving the printing surface is a copper or steel plate; the design is scratched into a coating on the plate and the plate then treated with acid. The acid works on the portion of the plate where the coating, or “resist,” has been scratched away, biting into it the original design. The plate is then inked and wiped leaving the ink remaining in the incised areas, which then allows the design to transfer to paper in the printing process.

A printmaking technique which transfers the inked image from lines cut in a metal (or plastic) plate to paper. The process needs a strong press.

The treating of a prepared polished metal surface with a chemical solution (typically acidic), or by other means, so that structural details of the metal surface are revealed. This may be a macro structure, or more commonly requires examination under an optical microscope.

An intaglio Process in which the lowered printing areas are bitten and etched by acid. The drawing and preparation of the plate can be accomplished with a variety of techniques dealt with elsewhere in this glossary. See Hardground, Sugar Lift and Softground.

A process of acid etching one side of float glass to obtain a distinctive, uniformly smooth and satin-like appearance.

Removal of material from a surface. Wet etching of silicon uses a chemical bath (usually potassium hydroxide). Dry etching uses gas, plasma or the blasting of particles.

is accomplished by coating a metal plate with an acid-resistant substance called ground. A fine-point needle is used to draw through the ground, exposing the metal below. The plate is immersed in acid, which bites or etches the exposed metal; varying the length of time the plate remains in the acid affects the character and depth of the lines. After the ink is rubbed onto the plate and pushed into the etched depressions, the unetched surfaces are wiped. The ink in the lines transfers to dampened paper when the plate and paper are passed through the press.

Printing technique in which a metal plate is first covered with a thin, acid-impervious coating called a ground that is smoked to a uniform black then worked with an etching needle to create an intaglio image. The exposed metal is eaten away in an acid bath, creating depressed lines that are later inked for printing. Different depths are achieved by covering some lines with acid-impervious varnish (stop-out) and biting others a second (or third) time. Etching surpassed engraving as the most popular graphic art during the active years of Rembrandt and Hercules Segher in the 17th century, and it remains one of the most versatile and subtle printing techniques today.

An intaglio printmaking process. A metal plate (zinc or copper) "bitten" with corrosive acid through lines scratched in a protective acid-resistant ground to create lines and textures. The plate is inked and printed on damp paper. In a press, the wet paper is forced down into the etched lines to grab the ink and transfer the image to the paper. Etching also refers to the printed image from an etched plate.

Incising lines into a metal plate with acid for intaglio printing. The plate is covered with an acid resistant ground through which the artist draws a design, revealing the bare metal beneath. When the plate is immersed in an acid bath these lines will be etched into the plate.

An etching needle is used to draw into a waxy ground over a metal plate. The plate is then submerged in an acid bath to remove the metal from the non-protected areas. The wax ground is then removed and ink is applied. Ink is wiped from the surface but not from the etched depressions. The impression on the print is from ink within the acid etched depressions.

Etching is a printing process in which an image is transferred from a metal plate onto paper.

Surface decoration bitten-in with acid, producing a different type bite than engraving. Copper stein, 1700s; pewter stein, early 1700s; silver plated pass cup with bone handles, late 1800s.

An intaglio process that uses acid to bite an image into a metal plate. The plate is coated with an acid-resistant emulsion or ground, through which the image is drawn or scratched with a needle. The plate is then placed in an acid bath that penetrates or bites into the exposed areas, creating the depressions that will hold the ink.

In the mechanical process, a design is masked off from the rest of the crystal or glass item. The piece is then "sandblasted" (acid is applied), resulting in the finished design.

Removal of portions of a layer of conductive material from a usually insulating base through chemical or electrolytic means. In wet etching, the material is dissolved when immersed in a chemical solution. In dry etching, the material is sputtered or dissolved using reactive ions or a vapor phase etchant.

A method of decorating a piece of glass. The two main types are acid etching and needle etching. In acid etching a piece is covered with an acid-resistant protective layer and then scratched with a design which is then exposed to hydrofluoric acid or acid fumes, thus leaving a frosted design when the protective layer is removed. Needle etching is a 20th century technique where a hand-held or mechanized needle is used to draw a fine-lined design on a piece. Ornate repetative designs were possible with the mechanized needle.

The chemical, or chaemcal and electrolytic, removal of selected conductive material to form a conductive pattern.

See Engraving.

A process where unwanted copper is removed via chemical processes.

The process of removing unwanted metallic substance (bonded to a base) via chemical, or chemical and electrolytic means.

Removal of material through the use of reactive chemicals or plasmas.

A method of printmaking in which the surface of a metal plate is scratched and then exposed to acid in order to deepen and widen the etched design. The print made from that plate can appear quite free and like a sketch.

A type of print. A metal plate is covered with an acid-resistant coating, then the artist scratches through the coating to make her design. The plate is immersed in an acid bath; the acid eats, or "etches," the plate wherever the coating has been removed. Ink is rolled over the plate, paper is placed on the plate, the two are squished together on a printing press, and the ink in the etched portions is transferred to the paper. The result is an etching. There is one plate for every color used; so expect to pay a good deal more for, say, a four-color etching than for a monocolor one.

is an intaglio printmaking process in which the design is worked onto a copperplate through a protective, acid-resistant ground, usually with an etching needle. The plate, still covered with the ground, is then dipped into an acid bath, which corrodes the exposed areas and creates furrows and troughs that will hold the ink. The depth of the etched lines is controlled by the strength of the acid and the amount of time the plate is exposed to it. After the ground is cleaned off, ink is spread over the surface of the plate and then carefully wiped off until it remains only in the etched lines. The ink is transferred from the incised lines to the sheet of paper by means of a printing press.

The process of rendering an image upon a metal plate by using nitric or other acid to dissolve portions of the metal surface. The image is transferred to paper in much the same manner as a dry point. Properly called a "print" or "proof" the resulting copy is more commonly called an etching.

an intaglio technique in which the entire plate is covered with asphaltum or other acid resistant material and the image is scratched into the surface to reveal the metal underneath. The plate is then immersed in acid which "eats" the line into the plate for printing.

An intaglio process in which the plate is marked by exposing it to the corrosive action of acid. The plate is first coated with a wax ground (which may be hard or soft), then the design is scratched with a needle or pointed implement, revealing the metal that is progressively bitten when the plate is immersed in acid. The reverse and edges of the plate are protected by a varnish that can also be applied at intervals to selected areas of the surface to limit the effect of the acid during the biting process. Both the varnish and ground are then removed by solvent and the plate is inked and printed. Because the ground offers very little resistance to the needle, a spontaneous line can be introduced, unlike the controlled line produced by the engraver's burin. Tone is ususally achieved by the aquatint process.

An image cut into the surface of a metal plate or glass with acid. This word is used also to describe a paper print made by an engraving process.

In etching, the plate is covered with an acid-resistant material. The artist uses an etching needle to scrape through this protective covering and then dips the plate into an acid bath. The acid can only eat into the metal where the protective material has been removed.

A chemical reaction process for stripping away solid material. Etching may be "wet" (using liquid chemicals) or "dry" (in a gas plasma). Etching is a key process in semiconductor manufacturing.

The technique of reproducing a design by coating a metal plate with wax and drawing with a sharp instrument called a stylus through the wax down to the metal. The plate is put in an acid bath, which eats away the incised lines; it is then heated to dissolve the wax and finally inked and printed on paper. The resulting print is called the etching.

is a contrast to engraving where acid is used to cut the plate. Once the plate is covered with an acid-resistant coating various tools are used to scratch through the surface exposing the metal. The plate is then immersed in an chemical acid bath that dissolves the exposed metal, etching a groove that holds the ink. True engraving show an impression of the plate around the edge of the image. A photo of an engraving will be absolutely flat.

The process of removing waste steel in the production of thin die plates. The peak of the cutting edge remains unetched being protected by a photoresist, imprinted in the form of the required profiles, on the face of the sheet.

The process of applying acids or other reagents to a metallic surfaces for the purpose of revealing structure details or surface characteristics. See Acid Etch Test.

The chemical treatment of a printing surface to incise a design or lettering.

Treatment of prepared metal surfaces with acid or other reagents which, by differential attack, reveal the structure.

A form of intaglio printing techniques in which ink is held beneath the surface of the plate. The ink is transferred from these shallow depressions to the paper through pressure applied by roller and blanket on a press. Mezzotint, dry point, etching, and aquatint etching are all intaglio processes. An acid resistant ground is applied to a plate, and then the artist “cuts” the image into the surface of the plate with a needle or similar sharp tool. The plate is then immersed in an acid bath, which eats away at the exposed lines, etching them into the plate. The longer the plate is left in the bath, the deeper the lines will be; the deeper the line, the more ink it holds, and the darker it prints on the paper. The plate is inked, wiped and run through the press for every print in the edition.

Inscribing lines of textures on the surface of rigid materials using acids or tools.

Acid and abrasive methods are used. A process that alters the surface of the glass. Used in conjunction with flashed or layered colors on a single sheet of glass. Acid eats the surface of glass away to reveal the color below. Abrasive etching uses pressurized media to abrade the surface of glass away. Often used to influence areas of shading within the figure section of a window.

The process in lithography by which the artist’s drawing on the stone is prepared for printing. The stone is treated with a weak acid solution that contains gum Arabic.

Forming a frosted surface on the glass for the purpose of defining all or part of the design or for changing the texture of the surface. This may be done by abrasive blasting, application of acid, by a copper wheel, or stone engraving or by diamond point scratching the surface.

Etching is done by coating the plate with an acid resistant ground and drawing into this with needles of different widths. When the plate is immersed in acid, the line is “etched” into the plate. The style is less linear and stiff than engraving. Tone can be achieved by hatching, cross hatching, stippling etc.

A metal plate usually copper or zinc is etched using various acids or mordands, Instead of cutting lines onto the plate, the artist covers the plate with a acid-resistant ground and then draws through that ground, with special sharp tools, exposing the plate where the design is to be. The plate is then immersed in an acid bath which bites into the plate where the protective coating has been removed. These bitten areas are what will hold ink.

The product to be imaged is coated with a resist (a protective coating that resists the acid). An image is exposed on the resist, usually photographically, leaving bare metal and protected metal. The acid attacks the exposed metal thus leaving the image etched into the surface of the metal. Very fine lines can be reproduced by this process and the only tooling is a piece of film, so spec samples are easily-made.

Etching involves the use of an acid for creating a design on a metal plate. The way it works is that with the help of a needle the design is scratched through a coating that resists acid. The metal beneath is exposed in these scratched parts. Such a plate is then immersed in an acid bath. The acid affects only these scratched parts creating the required designs. The depth of the lines is directly proportional to the duration of time for which the plate remains immersed in the acid. If a certain part of the design needs to be emphasized, the process can be repeated for those parts. The rest of the parts that are to be protected from the acid are coated with varnish.

A printing method popular during the 17th Century, in which a metal plate is covered with an acid resistant material and the artist scratches an image into the plate with an etching needle. When the exposed metal is eaten away in an acid bath, it creates depressed lines that are later inked for printing. Each etching is an original print because it is pulled directly from the plate on which the artist has created the image.

An image created by the artist on a metal plate by means of engraving tools and acid. This produces the sunken line which will receive the ink. As the plate is inked, the ink settles in the sunken areas. The plate is then wiped clean. The plate, in contact with damp paper is passed through a roller press, and the paper is forced into the sunken area to receive the ink.

The technique of using an acid based creme or liquid to impart a frosted appearance to glass, usually over a stick-on pattern. Stronger acid mixes may be used to eat away a different layer of color from glass, similar to the cameo concept. Less commonly, the use of diamond tipped pens to scratch into glass.

Surface preparation of metal by chemical process. Removal of a layer of the base metal.

The decorative technique most commonly used on arms and armor. The process consists of tracing a design into the metal with an etching needle through a previously applied acid-resistant substance like varnish. The application of acid "bites" into the exposed surface, leaving a permanent pattern which can be blackened or gilded after the varnish is removed.

decorative technique, the application of a design or pattern to the front surface of metal using acid to remove metal from the surface

Using a process in which an image is first covered with a protective coating that resists acid, then exposed, leaving bare metal and protected metal. The acid attacks only the exposed metal, leaving the image etched onto the surface.

Etching is a process of deterioration when acid eats away at metal. Bug guts contain a lot of acid, which will etch into an automobile's finish if left unwashed for 48 hours or more. Etching also has practical uses. Artists from Rembrandt to Pablo Picasso have used an acid etch printmaking technique to create staggering works of genius.

this is an intaglio method in which lines are bitten by acid, having been drawn with a sharp etching needle on a plate which has been covered with an acid-resistant ground. The strength of the line will vary with the strength of the acid and the length of time it has been exposed to the acid. This technique produces a rougher line than engraving but allows much greater ease of drawing. Rembrandt was the first great master of the medium. Whistler is another renowned expert.

Printmaking method in which lines and image areas are created by first coating a plate with an acid-resistant substance, then scratching through the substance with a sharp needle, and finally immersing the plate in acid, which “bites” depressions into the

A negative version of the artwork required is printed onto the plate in etch-resistant ink. The plate is then passed through corrosive acid, which affects only the exposed metal to produce a design with high quality (since it can incorporate detail such as half-tones), elegance and a long-lasting, durable finish.

A print made by coating a copper plate with an acid-resistant resin and drawing through this ground, exposing the metal with a sharp instrument called a stylus. The plate is bathed in acid which eats into the lines; it is then heated to remove the resin, and finally inked and printed on paper. The techique itself is also called etching.

Form of print created by cutting the image into a specially coated plate using acid.

A printmaking method of incising a metal plate with acid through a wax ground.

A design made on an object using acid or sand-blasting; the design is scratched through a protective coating and the object is immersed in acid or blasted with fine particles of sand to create the design. In printmaking, this intaglio process involves treating the plate with an acid-resistant ground. The artist draws through the ground with various tools to expose the metal. The plate is then immersed in an acid bath where the acid "bites" or chemically dissolves the exposed lines. The metal plate is therefore "carved" or "etched" by the acid rather than by a tool directly in the metal.

Glass may be etched by hydroflouric acid, HF1, which likes silica. Dangerous.

the process of removing a material by chemical reaction.

As applied to mill products and forgings, an attack by corrosive media resulting in pitting, mealiness or outline of structural details of the metal. In metallography, the process of revealing structural details by the preferential attack of reagents on a metal surface.

The technique by which a form of wax or resist is placed onto the metal surfaced and scraped off in preparation for an acid bath (generally nitric acid or a mix of nitric, sulfuric acids and water). The resulting effect is to quickly remove metal and produce a striking visual effect. Used most often during the 16th and 17th centuries, there are only scattered references from the 14th and 15th centuries, although the technique appears in common use in jewelry and art metal. Most decoration during these periods was restricted to engraving, painting, or studding.

An intaglio printing process using acid to create an image on a metal plate. The design is scratched through an acid-resistant coating with a needle, exposing the metal below. Dipping the plate into an acid bath bites away the lines of the design. This plate can then be inked and pressed against paper, producing a print which is also called an etching.

A process of decoration produced by what might be properly called "chemical engraving". The silver is covered with a protective coating through which the desired design is cut and the design is eaten into the silver by nitric acid. Electrolysis barking by the "electromark" process produces a permanent mark on metal - no acids used - Black mark if AC used - White mark if DC used.

Corrosion of the surface of a vessel, plumbing, equipment or fixtures. Plaster etching is caused by corrosive or aggressive water, usually because the pH and alkalinity are too low.

Surface decoration bitten-in with nitric acid.

The image is created by the controlled erosion by acid on the surface of a metal plate. Firstly, the plate is covered with an acid resistant ground. The image is then drawn into the ground with a sharp point to reveal the metal below. The metal plate is then immersed in acid which eats into the exposed metal lines. The length of time the plate remains in the acid bath determines the depth of the lines. Deeper lines hold more ink and will print darker.

A printing process. A metal plate is covered with an acid-resisting ground. The design is scratched through this ground, exposing the metal beneath. The plate is then immersed in an acid bath, causing the scratched or exposed areas to be eaten away. The plate is wiped clean, inked and the higher surfaces cleaned again, allowing the ink to remain in the incised areas. A press is then used to transfer the image onto paper. (n) Art work so executed. fabric mat A mat which has been covered with fabric.

A process in which a metal plate is coated with wax through which lines are cut. A corrosive acid is applied, which removes the metal under the lines.

A form of intaglio printing in which the lines of the design are drawn on the metal plate and then bitten (etched or eaten away) by acid.

Technique where a soft ground is laid on a copper or tin metal plate, and using a sharp etching tool, the artist draws through the ground, exposing the metal plate. The lines of exposed metal are then "bitten" in an acid bath. The strength of the acid and the length of time the plate is bathed determines the depth of the lines. After the ground is removed the artist inks the plate, making sure that the etched lines are filled with ink. The excess ink is wiped away, the plate placed, face up on the press and the paper face down. The pressure of the heavy rollers on the press is so great it leaves the impression of the plate on the paper and pushes the ink onto the surface.

This process is done with hydrofluoric acid, the only acid that attacks glass. Removing the surface color of flashed antique glass either fully to expose the body colour of the glasss or partially to lighten the flashed colour. The purpose of etching is to save cutting and leading of tiny pieces. Etching can be done only on flashed glass.

A process in which an etching needle is used to draw into a wax ground applied over a metal plate. The plate is then submerged in a series of acid baths, each biting into the metal surface only where unprotected by the wax. The wax is removed, ink is forced into the etched depressions, the unetched surfaces wiped, and an impression is printed.
