The manufacturer claims this is a milled and air floated Lincoln fire clay. It is an excellent all purpose clay with high strength and plasticity.

Ground to 200 mesh, this is a refractory plastic smooth tan burning very smooth plastic clay with kaolin-like working properties. Although referred to as a fireclay, it bloats by cone 11. It is yellowish in the raw state.

To formulate a substitute for Newman fireclay we mixed this 50:50 with Carbondale Red and added 15% silica and made a body containing 50% Newman. The results showed that this mix has less color than Newman and is quite a bit more vitreous. Much more silica will be needed to cut the maturity and this will result in loss of color making the addition of iron necessary.

Physical data can be found on the link to the product information web page of the manufacturer.
