Spectrum Ash glazes for cone 6 electric kilns: Ash glazing dates to 1500 BC. The process of using wood ash to glaze
pottery created a multi-tonal effect. Ashes from various fruit trees
would create beautiful colors. Spectrum 1420 Series cone 4-6 glazes replicates the look of these glazes. The colors are translucent, which
allows them to be used together for a unique appearance on every piece.
We recommend trying different techniques with your Spectrum Ash Glazes
until you discover the one that works best for you. One thin coat may
give you the look you desire, though multiple coats offer an entirely
different look. These cone 4-6 glazes also work well when combined with other glazes.
Ash glazes are oxide based. They can be used with cone 03-05 bisque ware. They mature at cone 4-6.
