Ash glaze.

Glazes made with ash have been used for over 3000 years. Most commonly the ash used comes from burnt wood logs, with different tree species offering subtle variations of colours from dark browns and olives through to lighter pale greens.

After being cleaned of harmful chemicals the wood ash is mixed with water and other materials to form a glaze mixture to be applied to pots before firing. This glaze mixture then melts under the heat of the kiln, combining with silica – an oxide found naturally in sand and quartz – in the clay to form a glassy surface on the pot.

Potters who wood-fire can also rely on the source of ash from their wood fuel for a ‘natural ash’ glazing. Ash particles carried around the kiln by the hot air and flames land and melt on the pots, often creating dramatic colour variations on their surfaces depending on their position in the kiln.
