Tin-chrome Pink Stoneware Glaze
I actually made this glaze ages ago, but I messed it up at the time. We were really short on tin oxide, but I thought I had got lucky and found some in the cupboard and only realised afterwards that I’d used zinc oxide instead of tin. Zinc and tin have very different effects in a glaze.
In the last photo you can see how it looked when I first made it - clear and slightly green from the chrome. I don’t think a single person ever used it for anything, which is unsurprising because it’s blah.
But, from doing the tests with tin-chrome for earthenware and reading the book that recipe came from about colour in glazes, I learnt how chrome and tin react.
By adding the tin I was supposed to add originally, I was about to completely transform a blah glaze into an awesome one.
I’m glad I tested on a small bowl too, because it looks even better on the bowl than on the test ring. The bowl is my reclaimed mix of PB103 and BRT.
They were fired to 1280°C which is approximately cone 9. I did a post about the firing profile we use for stoneware.

Update: I’ve decided to call this glaze Strawberries and Cream.
