This teabowl is stoneware clay, thrown on the wheel and then carved by hand.
The glaze combination involves using a copper rutile glaze inside the pot, then a glaze high in iron on the outside, with the same copper rutile glaze over the top.
Approximate size: 10 cm (height) x 9 cm (width)
To keep the teabowl in good condition I recommend not using a dishwasher, as the surface is a glass it will tarnish with time, as glasses do.
I will post the pots within 2-3 working days, if for any reason this is not possible, I will let you know.
The pots will be sent second class post which should take approximately 3-5 days.
