Lee,
Do you have any pictures of this? Sounds like an interesting process. Do you just make a saturated solution and leave the peice in there. Do you need to keep stiring the solution while the peice is submereged? any info would be great.
Thanks
David

If you do a scratch test of the glaze surface, it is the best
way to know the actual thickness of the application. It takes time to
learn. One thing you can do is dip two tiles for every test. Scratch
test them and then save one set unfired to measure future applications
against.

I don't have any photos. I experimented with it before my first
digital camera. It is from an old CM article: April '84 page 38
cone 10 reduction
12 cups soda ash
3 gallons water
Soda porcelain. Let dry for one week. Reduce after 1850*C
I might try some of my shigaraki clay with it in the next
firing. I tried it with stoneware and it come out ugly: sorta burnt
looking.
