Spectrum Underglazes

Sorry, we no longer carry Spectrum Underglazes

Rich, vibrant underglaze colors that are opaque with 3 coats, semi-opaque with 2 coats and semi-transparent with one coat.  They are compatible with most clear glazes.  They may be applied to greenware or bisque.  Made with frits, not slip, so you don't need an overglaze.  Lead-free, dinnerware safe, and rated AP non-toxic.  When used without a clear glaze cover they have a matte velvet like surface.  However, when used without a clear glaze cover they are not considered dinnerware safe because the rough surface can be difficult to clean and can encourage bacteria growth.  

The color chips show the unglazed color in the upper left half and the lower right is covered with a clear gloss glaze.  The samples were fired at cone 05.  They generally have good color stability up to cone 6.  The red and orange are based on cadmium encapsulated stains.
