Old Brick is a deep, glossy maroon glaze that is reminiscent of toasty reduction high fire red glazes with beautiful effects that can be achieved at low temperatures. This glaze is formulated to allow the clay body to show through where there is texture and looks dramatically different on red ware and white ware.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
