Mel,
Ah, simplicity! How wonderful! Volcanic ash can be a great glaze
ingredient.
Those who haven't used it need to recognize what those who have used it
already know -- not all volcanic ashes are alike.
Mel's Volcanic Ash glaze works with lots of colorants because the iron
content of the ash is relatively low.
Mt. St. Helen's ash will produce some different results. It has a
relatively high iron content, so it isn't as nice with coloring oxides. For
those in the U.S., the midwest and New Mexico ash seems to be much lower in
iron.
In hopes that someone new to this material finds this helpful.....
Dave Finkelnburg, still enjoying the rich scent of deep purple
lilacs around the house

I have some Volcanic ash that I got from Piedmont before they sold to
Campbells, so I have no idea where they got it. I've seen the VA/GB glaze;
gonna try it with some of that Murray's Borate and see what I get.
