A series of hairline cracks, normally less than a thirty-second of an inch in depth in the outer surface of a concrete product. Crazing does not constitute cause for rejection of Cast Stone.

Unintentional crackling of the glaze due to the differences in the rates of expansion and contraction during firing and cooling. Crazing may also occur any time after the pottery is made and will destroy the impermeability of the glaze.

Crazing describes small hairline cracks that can appear over time. Crazing is often caused by a mismatch in the thermal expansions of surfaces. There are ways to treat crazing; however if crazing is visible, it is an indication of a significant problem which needs expert attention.

This is the name for the unpredictable pattern of cracks in the glaze after it cools. It is a form of the word crazy; unpredictable random behavior. On earthenware pottery crazing is considered a undesirable fault. For food serving ware, it permits liquids to penetrate the glaze and foster bacteria. Out door planters will fracture when they freeze, if the glaze allows water to enter the clay body.

Crazing is the development of fine cracks, extending in a network on the surface—or beneath the surface—of a plastics material.

Fine network of cracks in a finish which may give an opaque appearance to the surface.

Minute cracks in the glaze of the figure. Many conditions can cause craszing, some nature and some due to expose to high heat or humidity.

A term that is widely used to define tiny, hair like cracks in the glaze of china, it can also be applied to composition dolls which present tiny cracks in their finish or their painted layers.

The appearance of a network of small cracks in a varnish coat or a plastic face stock.

The cracking of the glaze in fine lines caused by uneven tension between glaze and body during cooling. The process is sometimes long delayed. It is considered a defect in earthenwares because they are porous and the vessel will not then hold liquid.

Fine cracks in the glaze of stoneware bottles which if cleaned properly do not in anyway detract from the items looks or collectablility, crazing is caused due to the age of the object.

Cracking in the glaze. In earthenware this can cause the body to become porous. This fault occurs when the glaze is in tension, when thermal changes create unequal expansion or contraction between the body and the glaze. It can also result from numerous technical inadequacies during manufacture.

Fine surface cracking in smooth concrete surfaces. Can be reduced/eliminated by removing the surface latence by acid etching.

Cracking of gel coat or resin due to stress.

Hairline cracks on the surface of concrete, cement render or plaster usually of random pattern over a large area or the whole surface.

A defect found in pack-hardened tools, manifested in surface markings.

Small hairline cracks in glazed surfaces that usually appear after firing but can appear years later. It is caused by a mismatch in the thermal expansions of glaze and body. A glaze of higher expansion shrinks more than the clay to which it is attached and therefore crazes. There are many treat-the-symptoms approaches to crazing but the bottom line is: If there is a thermal mismatch it will reveal itself sooner or later no matter how you adjust firing or glaze thickness to hide the problem. If crazing is visible, it is an indication of a significant problem. This is because long before crazing becomes visible, serious strength problems result where glaze and clay are not expansion-compatible. See the Magic of Fire book for many chapters on dealing with crazing. Ceramic calculations are very useful in dealing with crazing and the INSIGHT manual has an example of dealing with a specific problem.

A defect in the glaze having tiny cracks between the body and glaze.

Tiny cracks in the clear over-glaze of the item. A few types of pottery are made with "crackle" glazes which are supposed to have this affect. On all other pottery, crazing was not an intended result of the manufacturing process and should be described as damage. It is for the individual collector to determine whether crazing is acceptable or not. Although faulty glazes or firing during the manufacturing process contribute to crazing, it is caused by exposure to temperature extremes after it has been completed. Crazing is never an indicator of age! It can occur 50 years or 50 minutes after a piece was originally made. Crazing may be described by the amount and whether any stains have gotten into it: for example, "small amount of crazing," "all-over crazing," "no staining," "light stains," "heavy staining."

A flaw characterized by a distorted surface or cracking.

An internal condition existing in the laminate base material in the form of connected white spots or crosses on or below the surface of the base laminate, reflecting the separation of glass fibres from resin at the connecting weave intersections.

1] Hairline cracking of a ceramic coating after firing due to internal stresses of tension or compression.[2] In organics, formation of surface cracks, often as a fine network, which do not penetrate to the substrate. Checking.

A network of cracks which sometimes forms in ceramic glazes; crackle. It may be desirable or not, depending on the artist's wishes. It is caused by the glaze and clay body contracting at different rates as they cool after firing. A similar pattern in the surface of oil paints is known as crackle instead of crazing. Crackle in oil paintings is less likely when the painter follows the rule of fat over lean -- when oil colors will be applied in layers (coats), the first layer should be leanest (least oil) followed by layers with progressively more fat (more oil.) Following this principle results in a work less likely to crack in aging. Similarly, in order to encourage crazing, later coats should have less oil than earlier ones.

Cracking in the glaze that occurs when the glaze shrinks more than the body after firing.

A condition existing in the base material in the form of connected white spots or "crosses" on or below the surface of the base material, reflecting the separation of fibers in the glass cloth and resin material.

Is similar to cracking, however, it is much less severe and does not destroy the basic function of the caulk. Crazing only extends a few molecules deep into the surface of the product (due again to excessive stress) and can occur during the curing phase or after being exposed to high elongation and weathering.

Fine cracks that may extend in a network on or under the surface of or through a layer of adhesive.

A network of checks or cracks appearing on the surface.

Surface cracks in the glaze, sometimes localised, and sometimes covering a whole piece. It is usually regarded as undesirable and is caused by shrinkage and other firing problems, but is often brought on by changes in temperature during long term storage of older pieces. The thicker pottery glazes are more susceptible to it than porcelain. Some potteries are now introducing it as a feature e.g. Poole Pottery's "Living Glaze" range, although they would argue that this is in fact crackle glaze rather than crazing.

fine cracks, which may extend in a network on or under the surface of a moulded part

Also referred to as "crackle" and "spiderwebbing", it is considered a defect in the glaze brought about by a difference in the amount of shrinking in the clay and the glaze. Usually undesirable, it is sometime used as a decorative element, but should be avoided for pieces intended for dinnerware and kitchenware. See also glaze.

A network of cracks in the glaze caused by tensile stresses greater than the glaze is able to withstand, and may result from mis-match of the glaze with the body.

In some pottery this is a design feature rather than a fault (See - Crackle), but in earthenware pots the cracks can allow moisture to penetrate to the porous body leading to further damage.

Also referred to as stress cracking, fine cracking which appears in the surface of paint, porcelain, etc.

Crazing, also known as alligatoring, is a phenomenon that frequently precedes fracture in some glassy thermoplastic polymers. Crazing occurs in regions of high hydrostatic tension, or in regions of very localized yielding, which leads to the formation of interpenetrating microvoids and smallfibrils. If an applied tensile load is sufficient, these bridges elongate and break, causing the microvoids to grow and coalesce; as microvoids coalesce, cracks begin to form.
