Good morning, Lili,
Yesterday I ran a series of little test tiles. I had left the bumps from the canvas on the clay for a little texture. I had 5 different glazes and made combinations, over/under etc of all possibilities in addition to plain colors.
Two tiles I dipped, one dipped over another color, the rest was brushed on: 2,3 and 4 layers. (because I had only small amounts of glaze left, anyway) I wanted to see the difference between the two as well.
The white - dipped - was good. nice texture, well-covered.
One of the blues was good, but it should have been satin.
Same blue over white was great: a much lighter, soft blue and satiny.
All the others were glossy (not all should have been) and barely covering the clay.
I fired, in my new caldera-S test kiln, to true ^6.
What can I do to get a more substantial glaze/glazing? I didn't invent any of the recipes but used some from John Hesselberth and some from a friend. I first want to have better results with what I do with the glazing.
Marianne-still bugging you :)
