In-glaze or inglaze is a method of decorating pottery, where the materials used allow painted decoration to be applied on the surface of the glaze before the glost firing so that it fuses into the glaze in the course of firing. [1] [2] It contrasts with the other main methods of adding painted colours to pottery.
Underglaze is a method of decorating pottery in which painted decoration is applied to the surface before it is covered with a transparent ceramic glaze and fired in a kiln. Because the glaze subsequently covers it, such decoration is completely durable, and it also allows the production of pottery with a surface that has a uniform sheen.
Overglaze decoration, overglaze enamelling, or on-glaze decoration, is a method of decorating pottery, most often porcelain, where the coloured decoration is applied on top of the already fired and glazed surface, and then fixed in a second firing at a relatively low temperature, often in a muffle kiln. It is often described as producing ...
Tin-glazing is the process of giving tin-glazed pottery items a ceramic glaze that is white, glossy and opaque, which is normally applied to red or buff earthenware. 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.
Underglaze decoration is applied before the glaze, usually to unfired pottery ("raw" or "greenware") but sometimes to "biscuit"-fired (an initial firing of some articles before the glazing and re-firing). [10] [11] [12] A wet glaze—usually transparent—is applied over the decoration. The pigment fuses with the glaze, and appears to be ...
Decoration technique whereby small moulded pieces of body are applied to an article before firing. Results in a relief decoration, such as is characteristic of Jasperware made by Wedgwood. [17] Spraying Glazing pottery by the application of a glaze suspension via a compressed air gun, similar to that for applying paint to cars. Also called ...
Ash glazes are ceramic glazes made from the ash of various kinds of wood or straw. They have historically been important in East Asia, especially Chinese pottery, Korean pottery, and Japanese pottery. [1] Many traditionalist East Asian potteries still use ash glazing, and it has seen a large revival in studio pottery in the West and East. Some ...
Black-glazed pottery was produced especially in the Classical and Hellenistic periods. During the reducing phase of the three-phase firing sintering of the iron-rich "clay paint" led to a shiny black glaze. Such pottery was produced both on the potter's wheel or impressed in pre-shaped matrixes. The glaze, originally in the form of a fine ...
