A hard translucent non-porous glaze on stoneware. Salt was thrown into the kiln at the moment of peak temperature, depositing a fine coating of soda and alumina on the surface of the ware giving it a thin, intensely hard film of transparent soda glass. It is characterized by tiny pin holes or granules giving it a rough surface.
a hard, glassy sodium-silicon glaze resulting from the vapors created by the introduction of salt (sodium) into the hot kiln atmosphere hear the end of a high temperature firing.
Pottery glazed by the salt vapor created by throwing crushed rock salt into the kiln during the firing process. American cobalt-decorated stoneware was salt-glazed and exhibits the characteristic "orange peel" texture of the surface. British potters used this process in the 18th century on highly-detailed, thin bodied white stoneware with a much more finely textured surface, found both plain and polychromed.
A semi-matte glaze created by injecting salt into the kiln during firing.
A transparent hard glaze with pitted surface obtained by throwing salt into the kiln at a certain temperature. When the salt volatizes, a chemical reaction takes place between the salt fumes and the silica in the clay, causing the glaze to form on the ware.
A glaze surface that forms on pots by introducing rock salt into the kiln at a high temperature. The salt volatilizes and combines with the silica in the clay to form sodium silicate.
an orange peel finish on pottery containers achieved by throwing salt into the kiln during firing. IGCB
Glossy finish for masonry, after it is fired with salt, caused by a thermochemical reaction of salt with the silicates in the masonry clay, and produces a smooth and almost impenetrable surface finish. Bricks of this type are easy to clean and are often used where the environment is harsh or where there is a chance for exposure to chemical or gases.
Salt firing is a process where unglazed ware is fired to high temperatures and salt fumes are introduced into the kiln chamber (normally by a spray in the burner ports). The sodium in the salt combines with the silica and alumina in the clay to form a glaze. The glaze is characterised by a pitted orange peel surface (although magnesium based slips may result in a smoother surface). The typical colours resulting from salt glaze are oranges, browns and blues. Notable exponents of the salt glaze technique are Walter Keeler and Michael Casson.
A glaze developed by throwing salt (NaCl) into kiln fired to maturity. The salt vaporizes and combines with the silica in the body to form sodium silicate, a hard, glassy glaze. The kiln interior becomes glazed itself which limits the kiln's use to the salt glazing process. Probably originated in the Rhineland during the 12th to 14th centuries.
A gloss finish obtained by thermochemical reaction between silicates of clay and vapors of salt or chemicals.
(or Soda Glaze) – a glaze formed on stoneware by throwing common salt into the kiln at peak temperatures, which vaporizes into sodium and chlorine. The sodium combines with the silicates in the clay stoneware to form a thin, colourless glaze that resembles the texture of orange peel.
a glaze created during high-temperature firings. sodium, usually in the form of rock salt, is thrown into the kiln during firing to form a clear coating on the clay, often with an orange-peel texture.
A glaze that is derived from the introduction of salt (usually common table salt) into the kiln atmosphere. The salt quickly decomposes and vaporized and combines with alumina and silica from the clay in the pieces, creating a glossy surface. This salt glaze actually adheres to everything within the kiln chamber so the wares must be placed on stilts or have the bottoms coated with materials resistant to the salt vapors. This renders the kiln a salt-glaze-only kiln. The one place this vaporizing glazing action does not occur is inside pots, unless they are shallow forms with a wide opening. To overcome this, many potters coat the insides with glaze prior to the firing. Decorative slips are often used on the outsides of the pieces. Pieces created with a salt glaze are sometimes referred to as saltware, and the process, because of the sodium in the salt, is also referred to as sodium firing or sodium glazing. This is a single-firing production process that produces a very durable glaze with the potential of very beautiful and interesting glaze patterns. Unfortunately, the process creates several very poisonous gases and is increasingly outlawed in many areas. See also glaze.
A glaze produced by the reaction, at elevated temperature, between the ceramic body surface and salt fumes produced in the kiln atmosphere.
A semi-mat or half-glossy glaze obtained by injecting salt into the kiln during the glaze firing.
Salt is introduced into the kiln chamber at specific tempertures. It vaporizes; creating a glaze type covering on the pottery within. Salt glaze has a drippy, mottled surface; much like the texture of an orange peel.
A glaze created during high-temperature firings. Sodium, usually in the form of rock salt, is introduced into the fully heated kiln and forms a clear coating on the clay, often with an orange-peel texture. Also referred to as Salt Firing Traditionally, rocksalt is thrown into the fire at the maturing temperature of the clay until an orange-peel textured clear glaze appears; contemporarily, any sodium put into a kiln at any temperature, or during a post-firing after a work has already been fired once; salt is deleterious to kiln bricks.
