Information AboutBisque (pottery) |
|
Bisque is a fired piece (bisquette) of unglazed Clay used to make Pottery , figurines, Doll s, knickknacks, ornaments etc. This porous, vitreous Ceramic can be created using heat, which causes a chemical reaction (dehydroxylation) in clay (e.g. Kaolinite ) to irreversibly change: # Unearth or procure Clay and mold, form, turn, wedge, cast or sculpt into the desired shape. Avoid air pockets. # Wrap the piece in plastic wrap and set in a moist environment for several days. Once air-dried, the clay piece is called greenware. # Apply no glaze. Place the greenware into a Kiln or similar Furnace and fire for about three days, a) dry the piece at a low temperature for about 12 hours, b) then fire the piece to approximately 1800 to 2260 °F (1000 to 1240 °C) for another day, c) and allow the bisquette to cool to a safe handling temperature of 150 °F (65 °C). |
