Glaze Tests
These are my latest glaze tests
Kate Malone recipe accredited to Emmanuel Cooper (High Alkaline Frit)
Crystals were lucky enough to grow without and special cooling cycle but they were in the bottom of a large kiln so cooled quite slowly

Glaze test
This bowl is my latest test piece hot out of the kiln! (it was actually still tinging when I took these shots!) I lined the inside of the BC (black chunky) Clay with porcelain slip to get a better colour response from the glazes I have been using. This is a crystalline glaze that Kate Malone uses. No crystals have grown but I think the finish is great. Crackles in the glaze, pooling in the middle and I love the way the BC has bleed into the glaze and trickled down the outside. This is the effect I was trying to achieve with manganese on other pieces. I might just put this on a little bit thinner so it's not quite so dark in the middle next time.... more test!
Hooray for BC Clay!!
Hooray for BC Clay!!
Black smooth clay
Latest experiment is black smooth clay with a crystalline laze on the inside. (fired to 1250)The black clay has given the glaze (turquoise on earthenware) a dramatic finish. Really pleased with this piece, one of my 'huggable' pieces!
HOWEVER!!! On writing this blog... I re-fired it to a higher temperature (1280) to see if the glaze would flow a bit more and it BROKE!!! It's now in 4 pieces and no longer a birthday present for my friend!
