With thanks to Bath Potters: I’d run out of blue glaze and the clock was ticking on the order – my glaze powder arrived the next day. Excellent service as always, and probably the best stoneware glazes on the planet.
In use, the LH jar contains a little cool water, the RH jar is filled with butter. RH jar upside down in LH jar for cool storage, RH jar as shown for serving. Cool eh?
