High Fired Tin Glaze

Ever curious what would happen if a tin glaze was fired at stoneware temperature….well John from Thursday morning class tried it and here is the result.  This is tin glaze over cobalt, manganese and copper oxides.  The glaze bubbles, leaving fantastic craters and texture.  Not everyones taste I’m sure but it’s right up my street and great as a decorative finish.  Always worth experimenting!

The tile in the background shows the result after earthenware firing. (smooth surface and stronger oxide colour)
