Old Copper is one of Spectrum's Low Stone glazes: low-fire glazes that give the appearance of a stoneware finish.
Unlike other earthenware glazes, Low-Stone glazes can create wonderful and surprising combinations when layered with one another. Require 2-3 coats for opaque coverage.
Low Stone glazes are all lead-free and dinnerware safe. However, they have Health Labels for use.
