About Ash Glazes
We collect ashes from friends’ fireplaces and, after screening them, spray them directly on some of our pottery before firing. The rivulets are a characteristic of the high surface tension and fluidity of ash glazes.
Before kilns were fired with natural gas, wood was used. Ash from the fire flew throughout the kiln and was deposited on the pottery, where it melted into a natural glaze. Today ash, soda and salt are sometimes used to mimic the ancient woodier process and create a natural glaze.
