This is a smooth plastic very high iron smooth fireclay. As far we know this is the same material as Jasper clay from Gladding McBean, but it is air floated at 200 mesh. It is a possible substitute for Newman red, however it is higher in iron.

This materials fine nature and high iron content make it suitable for terra sigillata.
