Sorry, I don't know the issue number of the magazine, but the potter whose
recipes you mention in your post is Lenore VanderKooi from Nashville,
Tennessee. I recall seeing the article recently during one of my lunchtime
perusals of the magazine stacks in my studio. If I come across it tomorrow
I'll try to remember to bring it home and make a copy for you.

Hi folks,
I'm trying to find an article from an issue of Pottery Making Illustrated from 1995-1999 (probably) that had several recipes for ash glazes in it; the ash glaze names on the lone page (p. 21) I have include Green Ash Glaze, Old Gold Ash Glaze, White Ash Glaze, Van Tan Ash Glaze, and Van Blue Ash Glaze; three others are listed there also but are not ash glazes.

I'd like to get a back issue of this if one exists, but first I need to know which one it is! If anyone knows, I'd be grateful if you'd share the info with me--
Thanks!

To the person looking for the PMI article,

I met Lenore when she was in Belgium visiting Patty Wauters a few
years ago. She used to be on clayart. At the time she was making pots
incorporating reed and bamboo elements but I think she eventually
went completely to doing baskets. Sort of a reverse Sandy Miller. ;-)

I did a search of the article index on PMI's site for "ash" and only
came up with these:

Not much help, do you have any other criteria?

You can get some really nice ash glazes just by doing line blends of
earthenware clay and ash. I did this in school and got some really
beautiful glazes. Very simple to mix as well.

Go to a woodstove store or an italian restaurant that has a wood
fired pizza oven or any restaurant that cooks with wood or visit all
your friends with fireplaces before the weather gets too warm.
They'll be glad to give you some. Get a good supply, mix it all
together really well and then treat it like any other materia.

Wash the ash if you want, it makes it more stable, less caustic but
less of a flux. Use rubber gloves and a sieve when you do this.

Otherwise, just dry sieve it through a window screen or a really
coarse sieve to get all the charcoal out and then through a finer
sieve, but not too fine and where a good mask. You don't want to
breath that stuff.

Then, to do a line blend, just set out 11 cups and then put:

10 parts clay/ 0 parts ash in the 1st
9 parts clay/1 part ash in the 2nd
8 parts clay/2 parts ash in the 3rd
7 parts clay/3 parts ash in the 4th
6 parts clay/4 parts ash in the 5th
5 parts clay/5 parts ash in the 6th
4 parts clay/6 parts ash in the 7th
3 parts clay/7 parts ash in the 8th
2 parts clay/ 8 parts ash in the 9th
1 part clay/ 9 parts ash in the 10th
0 parts clay/ 10 parts ash in the 11th

Actually you don't probably don't need to test the last 3 or 4,
they're going to be pretty runny and probably not usable. Make sure
you fire your tests on clay "cookies" in case they run too much.

Have a ball!
