By using the Malinite and adjusting the kiln temperature for a one fire process, the company solved the crazing problem in their own product. Glaze was applied to the unfired body, and the glaze and body matured together in the kiln, saving the company the time and expense of separate biscuit firing for the body. For the new line of pottery ...

[1] Glazing renders earthenware impermeable to water, sealing the inherent porosity of earthenware. It also gives a tougher surface.

The glaze has glasslike and pooling (buildup of glaze) characteristics which puts emphasis on the surface texture of the piece being glazed. When the glaze is mostly made up of wood ash, the final result is mostly dark brown to green. The pots with these glazes resemble the earth in color and texture.
Tin-glaze is plain lead glaze with a small amount of tin oxide added. [1] The opacity and whiteness of tin glaze encourage its frequent decoration. Historically this has mostly been done before the single firing, when the colours blend into the glaze, but since the 17th century also using overglaze enamels, with a light second firing, allowing ...
Glazes can change the chroma, value, hue and texture of a surface. Glazes consist of a great amount of binding medium in relation to a very small amount of pigment. [1] Drying time will depend on the amount and type of paint medium used in the glaze. The medium, base, or vehicle is the mixture to which the dry pigment is added.
In French faience, the in-glaze technique is known as grand feu ("big fire") and the one using enamels as petit feu ("little fire"). [4] Most styles in this group, such as Delftware , mostly used blue and white pottery decoration, but Italian maiolica was fully polychrome, using the range of in- and underglaze colours available.
