I think that you can get volcanic ash at just about any ceramic supply shop. I have gotten mine most recently from Bailey's.

My wife has been looking for a turquoise like this and such an effect. Nice piece. Where do you procure Volcanic Ash?
-
-
Yes Donna you'er right. I guess that I have tweaked this recipe around a bit and stopped taking it back to 100. The copper and tin are not in percents they are just a number.

Wonderful piece and glazing by the by

Since the glaze does not add up to 100% are you adding in a 106 gram recipe 10.6 tin and 6.36 copper or is the % really just treating the recipe as 100? I know that is an odd question but I am thinking the Bentonite and Magnesium got added after the fact in the recipe so the two colorant/opacifiers are as they are and not %. Curiousity running my mouth here.

Thank you Tony for the recipe. looks like fun. Happy firing.

I don't know where I got this glaze and I don't know how much I have changed it over the years. I am a pretty bad note keeper.
Cone 6 electric
Volcanic ash 82
Whiting 8.3
Lithium carbonate 7.6
Gerstley borate 2.1
Bentonite 1
Magnesium carbonate 5
add
6% Black copper carbonate
10% Tin
This is the blue green glaze over the Tenmoku style glaze which is breaking the surface like an oil spot glaze.

yes, could not agree more, one of the hardest things for me is to know when to stop glazing.

Thanks Carl,
Anyone can over work a pot disguising poor technique, I like to keep it simple. Sometimes the hardest thing to do is let a simple form be what it is.
