Flame is an opaque, glossy, mottled red glaze that breaks dark brown over texture. This glaze needs to be fired to witness cone 6 for color development. If it is under fired it will turn brown.
This glaze comes dry and is made for dipping and pouring for cone 6.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
