Spectrum 1420 Series Ash Glazes

The Cone 4/6 Ash glazes by Spectrum are all lead-free, dinnerware safe, and A/P non-toxic. The ash glazes are not designed to cover entire surfaces, instead they are intended to be used in a single coat on the top or rim of vertical surfaces and allowed to run and intermix with other glazes on the piece and create exciting and fascinating color variations and effects.
