What are the 3 kinds of clay Most potters use?
The three most common types of clay are earthenware, stoneware, and kaolin. Earthenware, or common clay, contains many minerals, such as iron oxide (rust), and in its raw state may contain some sand or small bits of rock.
When something burns which gas is used up?
Carbon dioxide is the most common gas produced by burning wood. As an organic material, wood is largely carbon and when exposed to heat in the fire this carbon changes into carbon dioxide, the same gas that is produced when any type of biomass is burnt.
What is GREY clay called?
Stoneware clay is malleable and often grey in its raw state. The type of firing that the clay undergoes will affect the clay’s colour – it ranges from light grey to medium grey and brown. Stoneware clay is usually fired at temperatures ranging from 1150°C – 1300°C (2100°F to 2372°F).

Are all glazes shiny?
Glazes high in glass former (SiO2, B2O3) are glossy. Those high in Al2O3 tend to be matte. Fluid glazes can crystallize to a matte surface if cooled slowly or a glossy surface if cooled quickly. The SiO2:Al2O3 ratio is taken as a general indicator of glaze gloss, ratios of more than 8:1 are likely to be glossy.
What two gases are released during a firing?
In complete combustion, the burning fuel will produce only water and carbon dioxide (no smoke or other products). The flame is typically blue. For this to happen, there needs to be enough oxygen to combine completely with the fuel gas.
