Roaster Ovens for rocks

<< < (2/3) > >>

mullet:
 I use a small toaster oven, it get's up to 550dgs.

Sleddman:
Just a couple of more things.  Take some tin foil, aluminum, and cover the sand before you put on the Lid. I use four layers of foul.  This will help slow down the cooling process. If your rock cools down too fast you have a much greater chance of blowing it up or putting some bad cracks into the rock. Let it cool down for two days, or close, before you grab the candy or you will have a desaster.  Knowing what the temp locations are you can put different types of flint, Chert, into the oven at the same time.   Good luck.  PS don't experiment with your best rock,  :-[

DanaM:
Wondering how primitive man got along before roasting ovens ;) ;D

cowboy:
I tried a roaster oven once. Took it up slowly and let cook for two days, can't remember for sure but think it went to 450 or 500. I couldn't tell any difference in the stone afterward :-\. May have been the type of rock I was treating..

Otoe Bow:
Thanks guys.  Paul:  The rock you tried in the toaster/roaster oven, were they like those Texas Diamonds you use :o  .   I'd say nothing short of Dente's Infernal will soften those up.   ;D

Dana, I'd love to build a big old fire to cook my rocks, but the weather conditions and dry grass are somewhat problematic.   8)
