551 Cone 6 White porcelain. Wins most vitrified award. Super smooth and creamy. Glazes are bright and brilliant on this clay. Great if you are staining clay bodies with mason stains or oxides (Nerikomi/Agateware). Cone 6 Shrinkage 13.0% Absorption 0.3% 630 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. Cone 6 Shrinkage 13.0% Absorption 1.5% 240 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. Cone 6 Shrinkage 13.0% Absorption 1.5% 420 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). Cone 6 Shrinkage 8.0% Absorption 1.5% 259 Lite Brown Clay a beautiful clay that is great for throwing. This clay is a lighter brown color with lots of light specks of grog that show up in the glaze firing. Cone 6 Shrinkage 12.5% Absorption 2.9% 760 Sand speckle clay. A finely grogged speckled clay. This clay is beautiful, it looks like wet beach sand when left unglazed. The speckles do not show through glazes and underglazes applied over this clay body. Cone 6 Shrinkage 13.5% Absorption 3.0% 211 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. Cone 6 Shrinkage 12.5% Absorption 2.0% 108 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. Cone 6 Shrinkage 10.5% Absorption 5.0% 308 Brooklyn red. 308 is a brick red stoneware body with fine sand and fine grog. Very resistant to warping and bloating. Yields a beautiful reddish brick color and can bring depth and richness to the glazes applied to it. Cone 6 Shrinkage 12.5% Absorption 2.0% 266 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. Cone 6 Shrinkage less than 12.5% Absorption less than 1.0% 112 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. C/6 Shrinkage 11.0% Absorption 2.25%
