Mid Fire Cone 5/6
A Jessica Putnam Phillips glaze.
Cobblestone is a warm toned semi-matte gray that breaks clear to the underlying clay body over textures and edges. This glaze will gloss up depending on firing & thickness of application.
This glaze comes dry and is made for dipping and pouring.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
