Best Types Of Clay For Throwing Ceramic Pottery: A Clay …
Earthenware. Earthenware is a low-fire clay body, usually in the cone 3-6 range. This is the softest of the clay types we're covering here, and is used extensively for things like brick making and tiles. This clay type can be a bit prone to breaking, as it's generally porous and doesn't get as hard after firing.

Firing Rocks With Clay Sculptures?
fellow newbie - i sent a PM if you want to see a pic of a small stone off park road mostly granite/clay/sand/ glass "technique piece." Most on wet clay- stone sand glass engobes bisqued, then some more glass added in spots some glaze and then fired to cone10 - glass with light crazing also flashed onto rock. Have fun!

Jerry Rothman "no-Shrink" Clay Body Recipe
Lightly coat these particles with a deflocculated clay slip. This slip. should have. no more than 25% water. (Think of a chocolate coated raisin) Firmly pack into-around shape. The more firmly packed, the better. Press clay into whatever voidss may be left in and around the particles. Dry and fire ---zero shrinkage.
Additives For Thermal Shock Resistance
mullite, kyanite, petalite, spodumene, etc - all the good stuff that effects thermal expansion in clays and glazes would be the first things i'd experiment with even though your friend is pulling clay from the same location, there are too many variables that can effect the chemistry of the clay he's actually digging up.

Clay and Glaze Chemistry
Pottery uses two varieties of clay: kaolin and ball, although a third group ( chlorite) does exist. There primary distinctions between the two are: 1. Kaolin has a 1:1 particle structure that will only hold water on the face of its platelets. This translates to; it will not add any appreciable viscosity to the glaze.

The Many Layers of Kiln Wash
Silicon dioxide has a melting point of 3100°F (1710°C) and aluminum oxide has a melting point of 3722°F (2050°C). Since potters fire to temperatures between 1100°F (593°C) and 2400°F (1315°C) a mixture of these two materials will not melt, will not form a eutectic, and will protect the kiln shelves. (The source of alumina in kiln wash ...
