Uro & Celadon not playing nice
Posted: Sun Oct 20, 2013 11:17 am
Hi everyone,
I fired a Uro (clear with ruby red broken up stringers - smooth to the touch) to a Spectrum Celadon - 12x12. I used a slow ramp up 200 dph to 1465 and held 10 min. Of course, there are more rates, but they're up with my kiln in the shed, and I'm here in my chair. The celadon cracked underneath - about 2/3 of the way - but healed. The problem is, you can see the crack because of the clear Uro. My shelf was probably cold - could this have caused that to happen? My question is can I flip and fire, use a more conservative schedule, and hopefully heal the celadon all the way.
I'd really hate to lose this piece - the two colors are really nice together and of course the cost.
Thanks for any and all suggestions.
Patty
