my latest kiln opening. I used Sapphire Blue and a 'top' dip of Waterfall Brown on everything but the tea pot and the 'scrap' casserole dish. I think I fired too hot and turned the blue to green. :o(

Hi Tom, Nice kiln opening. Your sapphire blue looks a little like Coyote's Pam's Green. I love it. A shame about the casserole. Possible stress crack.  Was the pot a little on the dry side during trimming?

Yea, the S crack was disappointing. I'm sure it was a stress crack. I never thought about it being too dry during trimming. Hmmmm. I usually trim them before they get very hard but with that large diameter, I might have waited longer. Don't remember, though. I guess that would put some stresses in it. I'll press the crap out of the next one and wrap it up so it takes a couple of weeks to stabilize and see how it goes. Oh, well the next one will be better anyway. It always is. :o)

Thanks for the encouragement!

I have to chime in and say that for a failed blue it's a really nice green! I wish my failures turned out that nicely.

Too bad about the cracks in the casserole. I can see the bottom crack coming from a lack of compression, but the side? Does the clay seem thinner there than the rest of the wall? What clay body was it? I'm finding that B-mix is becoming a problem that way.

Yea, the bottom 's' crack is all too familiar. I compressed the heck out of it and even used a 'strong arm' gadget I made to make sure the bottom was even. Used a wet box too. Next time, I'm wrapping it in plastic for a couple of weeks like some do. Everyone has their own 'proven' method of preventing 'S' cracks but I've tried about all of them.

I am using a Standard 140 clay right now.

Thanks for the comments!

Nice load. Are these glaze recipes in the book you mentioned?

[pensandcalls]

Thanks, appreciate it! The blend of blue and green with the brown flowing down does look pretty cool. Don't know why they call it a snot green.

Hey Tom, great kiln opening!!! I know that you were shooting for bluer, but these are still beautiful!!! I love 'em. Now you've learned how to get to this color. Always learning as Simon would say.
