Within commercial production there is a decline in underglaze use in comparison to 18th century use due to the creation and improvement of other glazing techniques that do not require such a high heat point. The vibrancy that only underglaze was able to supply is now achievable with a variety of over-glazes therefore discounting the advantage ...
Underglaze decoration may then be applied, followed by glaze, which is fired so it bonds to the body. The glazed porcelain may then be painted with overglaze decoration and fired again to bond the paint with the glaze. Most pieces use only one of underglaze or overglaze painting, the latter often being referred to as "enamelled".
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 ...
Decorating ceramic pieces doesn’t have to be limited to glazes and slips. You can also draw on your in-progress pieces using brush-less implements such as underglaze pens, chalks, pencils, and more.
Porcelain often receives underglaze decoration using pigments that include cobalt oxide and copper, or overglaze enamels, allowing a wider range of colours. Like many earlier wares, modern porcelains are often biscuit -fired at around 1,000 °C (1,830 °F), coated with glaze and then sent for a second glaze -firing at a temperature of about ...
Small cup with the "Five Treasures", Chenghua reign mark, 2.9 × 7 cm, PDF.767. Doucai (Chinese: 斗彩; Wade–Giles: tou-ts'ai) is a technique in painting Chinese porcelain, where parts of the design, and some outlines of the rest, are painted in underglaze blue, and the piece is then glazed and fired.
The wucai technique was a similar combination, with underglaze blue used more widely for highlights. [69] Two-colour wares, using underglaze blue and an overglaze colour, usually red, also produced very fine results. A number of different other methods using coloured glazes were tried, often with images lightly incised into the body.
Differences can be seen to the naked eye due to discoloration, being matched poorly, and change in texture or gloss. Subtle difference can also be seen by restorers by using lighting and magnification. Overpaint and surface coatings can be removed either mechanically or with the use of solvents.
