Ash Glaze

The one on the left is my second attempt at making a glaze from the ash's from the Horse Chestnut trees at Barrington Court.

It's only 33% Ash so does that count as an Ash Glaze?
It gives a nice colour to the bare clay with some light speckeling.
I'm going to try adding some colour as well.

33% is a third - that's quite a lot - that's more than some of the recipes in Rogers' book. I don't see why you couldn't call it an ash glaze.

At breakfast I was amused to read the ingredients of the "Olivio Extra Virgin cholesterol free spread" (margarine) we had been using. This contains a minimum of 21% olive oil, of which 5% is extra virgin. Your 33% ash glaze puts those claims to shame. Yes, you have an ash glaze and that is something of an achievement at your firing temperature. You look like you have got a good glaze fit too. Have you put the glaze over a white slip, and is there some tin oxide in the slip? I imagine that you will have some nice colours using 1- 3% copper carbonate with the glaze due to the alkaline character of the ash. Good luck!

Sounds like an ash glaze to me, Paul. As Peter said, a lot of Phil's ash glaze recipes come in well below 33 percent. And it's your glaze; you can call it anything you want.

ash... I like sprinkling my pots with soda ash. I really like the effect... keep at it with the ash. It's been fun to learn from your work on your blog.

Amy said...

oh, forgot to ask. Did you sprinkle the ash on after you diped the pot in glaze or mix the ash with the glaze?

Looks good Paul. Ready for the next round of tests with the oxides.
