It's been a few years since I've had more than 2 glazes. Now I have 6. I've been doing some exhaustive glaze testing for the past few months and have some promising glazes to work with. My next firing is going to be all glazed work, no slips, no salt(well, some residual salt.) If I can keep the top shelf from blistering I'll be good to go. The next firing is coming up real fast...better get some wood chopped.

Are those all Ash Glazes? Do you have any experience single firing ash glazes in oxidation? I'm looking for an oxidation glazing scheme (that I can stand) to hold me over until I can get a wood kiln built, as my cone 10 Ox kiln is all I have access to at the moment.
Chris Early, a former Hewitt apprentice, and acquaintance of Joe Cole, was doing it in Cincinnati with some success but he's since moved on to grad school. Just wondering if you've ever tried it.

well...i've had glazes that have oxidized...never on purpose though. all of these are ash glazes...and i have a shino that i'll glaze about 5 pieces with. i would think any ash glaze with a high amount of iron/colarant would do ok in oxidation. the low iron greens turn a snotty yellow-green in ox. tenmokus can do well in ox. I used to use my 442 with something like 8% bentonite for raw glazing. most glazes high in feldspars and/or clay will do ok for raw glazing. have you seen steven hill's oxidation pots? not that you should glaze like him but his slow cooled oxidation pots are indentical to his redux. pots. interesting stuff. willem gebben in colfax wisconsin does tons of work with ash glazes and single fires all of it(redux.). you could write him for advice.

I've met him. Really cool fella. Like his little place too. I'll have to give him a call.

did you really fire your wood kiln on that tiny bit of wood in the photos? I'm impressed.

brandon phillips said...'s a pretty efficient kiln, and i fire fast. i can sort, cut, chop, and stack enough wood for one firing in about 4-5 hours.
