It is possible for certain types of food to become contaminated if stored or presented in an unsafe container, such as a ceramic pot with lead-based glaze.

Flesh is a mere glaze under which the features are indicated by lines.

Limited interest has been shown in low friction properties of compacted oxide glaze layers formed at several hundred degrees Celsius in metallic sliding systems, however, practical use is still many years away due to their physically unstable nature.

A further phenomenon that has undergone investigation in relation to high temperature wear prevention and lubrication, is that of a compacted oxide layer glaze formation.

This is the generation of a compacted oxide layer which sinters together to form a crystalline ' glaze ' ( not the amorphous layer seen in pottery ) generally at high temperatures, from metallic surfaces sliding against each other ( or a metallic surface against a ceramic surface ).

As the ' glaze ' is already an oxide, it can survive to very high temperatures in air or oxidising environments.

The amount of oxygen that is allowed during the firing and cooling process affects the resulting color of the glaze and the amount of crackle.

Western raku is typically made from a stoneware clay body, bisque fired at and glaze fired ( the final firing ) between, which falls into the cone 06 firing temperature range.

Wax resist, which is painted over the bare untainted clay, results in the suspension of wax in water before the raku glaze goes on.

This is done so that the glaze does not cover the area where the wax resist was applied, thus creating a design.

For example, cobalt produces dark-blue, and copper produces green but produces a red when the oxygen in the glaze is completely gone.

Crazing is a consistent cracking in the glaze of a piece, as is seen on the white crackle glaze.

The final extraction, consisting largely of colorless material as well as a few blue particles, brings forth ultramarine ash which is prized as a glaze for its pale blue transparency.

It is processed and sold as dry flakes ( pictured at right ), which are dissolved in ethyl alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish.

Shellac is edible and it is used as a glazing agent on pills ( see excipients ) and candies in the form of pharmaceutical glaze ( or, confectioner's glaze ).

This technique was primarily used by potters who would glaze their wares and then scratch a design into it.

Although almost any low-fire glaze can be used, potters often use specially formulated glaze recipes that " crackle " or craze ( present a cracked appearance ), because the crazing lines take on a dark color from the carbon.

* Alum may be used to increase the viscosity of a ceramic glaze suspension ; this makes the glaze more readily adherent and slows its rate of sedimentation.

Lichtenstein then applied a glaze to create the same sort of graphic motifs that he used in his paintings ; the application of black lines and Ben-day dots to three-dimensional objects resulted in a flattening of the form

Clay from Crawford County and the Rich Hill alkaline glaze used by the early " jug makers " is still prized today.

The following section provides background information on the methods used to form, decorate, finish, glaze, and fire ceramic wares.

Many types of glaze, such as the iron-containing glaze used on the celadon wares of Longquan, were designed specifically for their striking effects on porcelain.

Tiles are most often made from porcelain, fired clay or ceramic with a hard glaze, but other materials are also commonly used, such as glass, metal, cork, and stone.

Modern materials such as concrete and plastic are also used and some clay tiles have a waterproof glaze.

However, the term " craze " is also used to refer to minute cracks in pottery glaze, again suggesting the metaphorical connection of cracked pots with questionable mental health.

Later examples used a yellowish lead glaze for the applied decorations which then stood out against the darker surface of the vessel ( Adler, 95 ).

Bunzlauer popularity increased even more after 1828 when the potter Johann Gottlieb Altmann produced a feldspar substitute for the dangerous lead glaze that previously had been used on the interior of the vessels.

To produce a better quality fired glaze finish twice firing can be used, and this can be especially important for formulations composed of highly carbonaceous clays.

Celadon glaze refers to a family of transparent glazes, many with pronounced ( and sometimes accentuated ) cracks in the glaze produced in a wide variety of colors, generally used on porcelain or stoneware clay bodies.

* Icing ( food ), a sweet and often creamy glaze made of sugar used to cover or decorate baked goods, such as cakes, cookies or donuts

Icing, also called frosting in the United States, is a sweet often creamy glaze made of sugar with a liquid such as water or milk, that is often enriched with ingredients such as butter, egg whites, cream cheese, or flavorings and is used to cover or decorate baked goods, such as cakes or cookies.

He also had to know when to quench the kiln with water so as to produce the surface glaze.

Porcelain insulators are made from clay, quartz or alumina and feldspar, and are covered with a smooth glaze to shed water.

Pieces with no glaze have nowhere to get the oxygen from, so they take it from clay.

Typically, pieces removed from the hot kiln are placed in masses of combustible material ( e. g., straw, sawdust, or newspaper ) to provide a reducing atmosphere for the glaze and to stain the exposed body surface with carbon.
