Chestnut Ash is so magical to use. Each tree grows for one hundred years, cumulating trace minerals. They help make prisms that reflect the light.
This ash is from Essex. The minerals in the clay have come to the surface, flooding into the glaze and sometimes the iron bleeds into a beauty spot.
The shape for this teabowl is ancient called ch'ien, and is said to be one of the first shapes, when tea was almost a soup drink, drank with salt and onion.
This teabowl is for sale. check my website for details.
