Green T test 2 turns out white

The latest test turned out white, with just the lightest shade of blue under the white. Kind of looks like snow on the ground....but glossy. Very crazed, not so nice really. Anyway have added 3% CuCO3 and have some on a small test bowl. Hopefully this will turn out better.

Green T test 2

The Green T test part two resulted in gaining the following knowledge.....the blue appears where the glaze is thicker. Large areas of blue have formed over the next test tile. Now mixing up a batch without copper to determine if copper is the reason or does a clear glaze form which turns blue when thick......does copper enhance the colour? Also some nice effects with iron splashed into the second glaze.......good bleeding potential.

The wee beauty salt kiln

Things often happen this way....I have been thinking about making a small vapor kiln for some time, and have made make shift ones in the past. Almost single use ones due to unsuitable bricks. But just after joining the Auckland Studio Potters ASP, the first newsletter arrives and the first article is about a newly built small salt kiln that fires in 6 hours and works well. 150 bricks used and a tank of LPG. I now have the plans for this kiln. Just three shelves, but that's enough for my low production and experimental work. Now what's holding me back you ask?
1) I have no bricks.
2) I have no burner except a raku burner which is under powered.
3) No kiln shelves.
4) the cost of fire bricks ranges from $5 each to $10 each.
5) Refractory coatings are another issue.
6) I don' have a large LPG gas tank.

These are the issues I am going to think about this year.
