I tested a few new Raku glazes today with some good results, some disasters. I'll photo a few disasters later. Like I put a plate in too wet and the entire middle blew out. This tea bowl is a black that I mixed up, only problem is I don't know what I used. I think it was my Soldner base 80/20 Gerstley Borate and Neph sye with black mason stain, but I don't know how much stain and I'm not sure this is correct. I must have written it down somewhere..... heard that one before? Anyway it is wonderful and I love is, so shiny and silky. Definitely a keeper if I figure it out. The little dish below is in the same glaze just reflecting a turquoise pot.
I like making these little dishes for test glazes. I just use a large size cookie cutter and cut out a bunch of them from the scraps left from slabs I use. I stamp them so I can see how the glaze breaks and if the glaze is runny the dish contains it pretty well. I encourage my students to make little dishes to try out the glazes at the Artscenter so they don't waste so much of their clay.
This is a translucent jade green that is also very nice with lots of depth. I do have this recipe but it's upstairs and I am not walking another step right now! If you are interested in the recipe let me know and I'll get it posted later. I'll also try to shoot better pics later. Too tired right now.
Some more raku houses, look at all those pin holes...... lord!
These are interesting tests. I first was testing a gerstley borate black oxide wash on these at ^6, they were pretty rough in texture and not so great, so I put one coat of copper red on them and got these. Except for the one top right. That was a commercial glaze from Laura that I put on too thick and it went yellow so I put the copper red on it and got a beautiful dish. The ones below got two coats, too much and all were fired too low, I think I will re fire these a little hotter, they are worth a save.
So Wes and I are off to the beach tomorrow, leaving poor Gerry here to work over the holiday :(
We will probably just sit around my mom's pool for three days and read. Bliss! I'll be back Tuesday and then off to a workshop with Judith Duff. Cannot wait for that!
