the agate? yes I did, I dropped it when cabbing so threw it in the tumbler will all the others this batch.I cook alot of my slabs and cabs. IF I dont like the color when I`m cabbing then I`ll put it in my pile of rock to cook and cook it, doesnt hurt it and turns it something else. Not all rocks will turn color BUT, it will make it easier to cab,promise you that. I cook alot of my jaspers also. Its the iron in the clay that surrounds the coral that dictates the colors it will turn.

Hey Jeff, for those of us that don't live in warm places, you told me about cooking slabs in an electric turkey roaster? Can you run those instructions again? Instead of the bird for thanksgiving, we'll have coral, LOL!!!!

I'm wondering if a crock pot would do the job, would it?

Inspirational. You're making that 2 watt bulb that floats above my head start to glow. Those brighter colors you achieve seem worth the risk and effort. Thanks for the post.

no on the crock pot.... for the turkey roaster you take the pan out and put dry clean sand in it. bury your slabs in it and and put the lid back on, I cover the inside of my lids with foil because it has a few vent hole. The older roasters went to 550 or 600 the newer ones only go to 450 Turn it on and keep it at 200 for a few hours just to get any moisture out. then every hour ramp it up 50 degrees till you max out and you can hold it there for 24hrs, then ramp it back down. Not all rocks will change color but alot of the cherts will, thats why the indians heat treated their rocks to make knapping it easier. It will make your rock,if cooked properly, eaiser. Heres a list I got from a flintknapping site
