Can you fire cone 10 glazes to cone 6?

The bottom line is that we cannot just reorganize a cone 10 recipe to melt at cone 6. We must add something new, a flux or fluxes not normally found in cone 10 glazes. They melt very early and vigorously and can impart significant melting effects in small amounts in some circumstances.

How long does a cone 10 firing take?

If well designed, it should be possible to predict the end of a firing accurately. For example, a cone 6-10 electric hobby kiln with elements in good condition should finish within 5-10 minutes of the projected. Industrial kilns, likewise, should finish within minutes of the target.

Can you fire to cone 10 in an electric kiln?

Firing to cone 10 in an electric kiln is difficult for most cone 10 rated kilns especially when on household power. With so many great clay bodies formulated for cone 6, a regular cone 10 electric kiln is a perfectly acceptable kiln for most potters working in stoneware.

How is tenmoku made?

It is made of feldspar, limestone, and iron oxide. The more quickly a piece is cooled, the blacker the glaze will be. Tenmokus are known for their variability. During their heating and cooling, several factors influence the formation of iron crystals within the glaze.
