Hi, I have just begun a pottery class and am having fun at it. For another class I had to observe a couple pieces at a museum, and in wandering around after having taken note of those pieces I happened across a modern bowl with a blue overglaze onto of a "yohen-type glaze." In looking on the internet, I found photos of virtually the same effect here:

Granted that I know no more about glazes than just the cheap clearglaze we paint onto our high-school pots, I would still like to learnmore about it. A google search thus far has turned up galleries andsome notes about potters, but no definitive step-by-step description ofhow to execute yohen glazes, let alone this particular hematite-likecrystalline yohen glaze. I learned that it involves charcoal or ash:-) But that's about it :-( Can it be done in the electric kilns wehave? If not, can a kiln be affordably built? Well, to be honest withmyself, I'm not likely to get around to building kilns or masteringyohen glazes when I've barely begun in pottery, but I'd still trulylove to learn more if you know of any books or websites or canpersonally tell me moe about it.
thanks! -Bernard Arnest
