Instructions


This glaze is great in the wood chamber of a noborigama. Albany Slip Sigillata is an excellent underglaze with Munn's Tenmoku. The glaze has a honey-amber (light reduction) to rich-iron (heavy reduction) appearance.

Glazing Over Terra Sigillatas

After bisque firing, the sigillata surface is less absorbent than the clay. When dipping and pouring glazes I adjust the glaze for the correct thickness on the bisque clay and then brush a light coating of additional glaze over the areas with the sigillatas. This includes when I am using the sigillata as an underglaze and where a glaze and sigillata overlap. Additionally, where there is an overlap, a light burning terra sigillata (Base, Off White, or Warm Earth Tone) will disappear and be absorbed into the glaze, with very little noticeable effect, while the oxide-rich sigillatas can be used as underglazes.
