Then you better have a desirable design on mind for a carving for yourself.

WOW! Those are the prettiest colors yet. The reds in your hand are gorgeous. And it was a mere extra 50 degrees more. I think our regular kitchen oven goes to 600.
Was 600 the temperature you used to get these beauties?

Those are fantastic James. I wonder what another 50 degrees would do, LOL. You know how guys always want to push until destruction. Didn't one of the smokers on Waterworld wear those same googles?

out of curiosity, could you have broken that big piece before cooking???
or were you just cooking to see what would happen, then broke it open after??

Really nice coral James. I am not sure how long you cook them for but if it's not hours and hours you could try to cook them in a self cleaning oven. I think the temp gets up to 900 plus degrees, a hell of a lot hotter than the hottest cooking setting anyway:). Beautiful material anyway!

John, i knew the kitchen oven was not quite hot enough.
My friend Stan(Stansknives) cooked some for me. I would say it went to 650 on the coral. The grainy coral got deep color and the glassy coral fractured.
So the 650 was ok for the grainy stuff. 550-600 for the glassy texture. And the books say 550-650 depending on grain size.
This weld rod oven is about perfect. It is rated at only 550, but it is hotter than that.
Well, most of you flint knappers use industrial ovens. I learned from you guys. Knappers are king of cooking rock. Thanks for looking

Kurt- Seeing your workmanship is payment enough. Your carving is certainly another level. Chuck-I was aware there was color advancement in the coral career. Just now getting around to the right oven. Pat-The top temp is a bit nebulous on an electric oven. Do not believe what they say. Best thing to do is stick known rock in there and cook it. Cooking rock is slow heating to your desired top temp, then hold to soak, and then slowly cool. If you do not hit the color changing temp you may get no change at all. Too hot and you will get fractured junk. When cooking under a camp fire a 5 minute gust of wind can fracture the whole batch quickly by raising the temp too quickly. Best to cook in an electric oven Mark-That was me on Waterworld. Thanks for noticing.

Mario-Yes you could have cooked the whole volleyball sized rock. I can easily cook basketball size in that oven.
Here is the problem.
If you cook a big coral head you got to raise the temp very very slowly to bring the heat in gradually or else you will pop it into numerous chunks(called exploding). I had no interest in running the oven like 2 days and have no saw to cut a chunk that big so i broke it into smaller pieces that could certainly be slabbed and cabbed.
The oven is only 1000 watts but is well insulated and efficiently shaped. The kitchen oven i was using is 2000 watts and would not get this hot.
This oven is cheap to operate. I would say the element was on for a total of 6 hours during the 24 hour bake job. And will cook 200 pounds at a time.

Tom-Noviculite is cooked at 800-900F. It is about the hottest i have ever seen a flint type quartz being cooked. Larry-I owe you for the Mcdermitt. Hope i can get to the river to collect more. Will try cooking some of that too. The thermostat is wacked and has a min temp of 330F. So i plug it for 15 minutes per hour for the first 3 hours to dehydrate. The company says the thermostat should hold 130 dergrees. Mine is messed up. But It costs $285 so i will live with it. This thing is 40 years old. And had no scale. So i have been putting the temps w/magic marker around the dial.And the knob came off of an old washing machine.

Wow, sweet stuff! Such dramatic transitions in the colors. I will be excited to see what Kurt will do with this material, he has taken Montana agates to a new and unique level, and I am sure he will make some stunning works! I inherited a kiln, think I might have to cook some rocks this winter.
