^02 Vitreous Engobes

I'm not sure I understand the problem. If you don't need the engobe as a base for further glazes, can't you just use ^02 glazes directly on the leather-hard pieces? Or are you looking for a really white base for translucent glazes?

How about the standard ^04 bisque and then glaze to ^02?

No I didn't state my case very clearly. I'm looking for ^02 Vitreous Engobes ( almost self glazing) I started out looking for ^02 glazes but most recipes I found are for ^06 or ^04. I came across Vitreous Engobes in my research but I found mostly ^6 in that category.

I want... A satin opaque surface that can hold water. The Engobe solution is intriguing in that I could do everything at leather hard and once fire (slowly)

I need to buy a test kiln and start testing.

Sounds like you just need a ^02 opaque satin glaze that works for single-fire, regardless of what it's called. Chappell's "The Potter's Complete Book of Clay and Glazes" has a whole chapter on single-fire glazes, including "SFG-5 Transparent Semi-gloss Base Glaze Cone 02" and "SFG-6 Transparent Smooth Matt Base Glaze cone 02". He also gives advice on matching the fit to the body.

I suspect you can take any normal ^04 or cooler gloss glaze and add some of your body clay to bring the maturing temperature up and the gloss down.

Thanks Bob. I got that book on hold at the library. I'd already been to two librarys to browse but the Chappell is in the oversize books and I didn't browse there.

Coming a little late to this and slightly sideways; we have found that Brush-on earthenware glazes will actually raw fire, an interesting and unusual side effect of adding CMC to glazes.

On the 02 subject it is perfectly possible to bisque fire to 02 and glaze at a lower temperature. However if the clay used is low in porosity at that temperature adding some Gum Arabic to the glaze will help it stick to the ware in the unfired state, and once melted it should be fine anyway.

Thanks Steve, I've been out of town and out of my studio. I think I'll try your suggestion of Gum Arabic and glaze on ^02 bisque. I did find some nice ^03 glazes that I want to test but... all in good time. Art Fair season is coming and I have work to do. I should just back off and do the conventional ^04 bisque with ^06 glaze and save my adventures in ^02/03 for post X-mas experimenting.
