but I don't know about how to wash the ash. Do you weigh it out in dry form
first?(I heat with red oak so that is what my ashes will be) and how do you
wash it. Wring it out, dry on a towell...? Any info would be welcome.
Thanks, Barb What size ash? The powder at the back of the stove or larger
chunks nearer the front.

Washing Ashes!
There may be a faster way, but when I was doing ash glazes for my M.A.,
I filled a large plastic barrel with two-thirds ash, then filled it with
water. Let it settle, and repeated this a couple of times. Then I
siphoned off all the water I could, and spread the ash slurry on
shelves, and dried it in the kiln with the pilot on. Then sieved it. Use
the dry and sifted ash by weight in glazes. A big job, but I had ash for
years for glazes. Finally left it behind in New Mexico somewhere, when I
moved to Hawaii.
