Gray (White) Stoneware. This is the clay we used to provide in the communal buckets. Contains fire clay and mullite which (supposedly) enhances thermal properties. Fires grayish and the fired unglazed clay looks like white stoneware at cone ten. This is a good clay for beginners because the grog in the clay helps prevent cracking during drying.  Some people have experienced bloating issues with this clay body.

Ivory (White) Stoneware.
A very smooth, plastic throwing body. This clay doesn’t have grog so it is more prone to cracking during drying, dry slowly to avoid this, not having grog allows you to sponge smooth this clay. 240 is a great clay for those who are nervous about trying porcelain but want a very smooth lighter colored clay. It is the brightest stoneware we have, it is very low in iron. The glazes show bright and clean on this clay.

Sculpture clay.
A highly grogged body, formulated for sculpture. Sand color at C/6.
This clay is a beautiful gray color when wet but don’t let that fool you, the clay fires a light straw tone. This clay is full of sandy gritty grog which can hurt some peoples hands when they throw with it. For this reason we do not recommend it for throwing (although some do). This clay is highly moldable and sticky. It is an excellent sculpture clay, producing works that dry evenly with less cracking and low shrinkage (only 8% vs the usual double digits).

Hazelnut Brown
Lisa Common turned us onto this clay, she uses it a lot in her test tiles. It is maybe one of the most beautiful brown clays available, not to light and not too dark, full of rich deep tones that really bring out the beauty of glazes.

Terra Cotta Red Sculpture clay.
This clay gives the lovely red tones associated with terra cotta but its actually a high fire stoneware. Great for sculpture, very rough for wheel throwing although we have seen it done.

Dark Brown Clay. People love this clay because it is so dark. It is described as giving a reduction look to any cone 6 glaze but its just the visual influence of all of the iron and manganese in the clay body showing through to create major depth and richness in color. The clay is smooth and plastic and good for all techniques. It may take longer to clean up your wheel splash pan with all the iron in this clay. Some have reported issues with warping and bloating.

Speckle clay. This is one of the most popular clay bodies because the speckles in the clay show through glazes and underglazes. Bisque looking unblemished brown? This clay will not reveal its speckled surface until its fired to glaze temperature.
