Made with stoneware clay and then carved when the pot was "leather hard". The carving allows nice areas for the glaze to pool and crystalize. The glaze is a Kings Creek Pottery original and was actually an accident! Thankfully I kept good records and could find my wonderful "mistake"! The carving technique I learned from the amazing potter, Cynthia Bringle, at the Worcester Center for Crafts a few years ago.
Another option for Mom two mugs and a gourmet pound of coffee:
Also made with stoneware clay, these mugs are imprinted with tibeten wood blocks when they are "leather hard". All Kings Creek Pottery is food safe, microwave, and dishwasher safe too!
Plenty more options at the shop in Gallupville or on the Kings Creek Pottery Etsy shop.
