My new copper blue glaze on a Loafers Glory test tile

Since I don't have any studio news at the moment, I thought I'd at least put some ceramic information on the blog once in a while. Here's a Cone 10 reduction copper barium test from my last soda/salt firing. The clay is Loafers Glory, a white, porcelainous type stoneware from Highwater.

I was looking for a buttery surface and this looks very promising. I'll probably use this  on small bud and ikebana vases with a white or shino liner. I got the idea of the copper and rutile percentages from an old Ruth Gowdy McKinley glaze.

Here's the formula is anyone is interested in trying it (of course be mindful that this is not a glaze for pots used for food. Barium carbonate and copper carb are toxic, so make sure you use safe studio practices when mixing, applying, etc.

June's Cone 10, Buttery BaO Copper blue #9785V2

38 Neph Sy
32 Barium Carb
17.3 OM #4 Ball clay
12.7 Silica
Add: 3% Copper carb, 6% rutile  

After lunch I started going through some of my old seeds and got a few cold weather veggies started (Cauliflower, Broccoli Raab, Cabbage, Parsley, etc.). After going through several seeds catalogs, I realize that I probably won't need to buy many more seeds, since I have plenty of just about everything.

I've got leftover turkey meatloaf for dinner, so I might use some of that kitchen time to start another loaf of cinnamon raisin bread to bake overnight if I can figure out that setting on the new bread machine!
