Title: Heat treatment
Post by: Allyn T on April 01, 2021, 09:44:37 am

I was reading D.C. waldorf's book and he has some really high temperatures for rock like burlington. If I use a turkey roaster it won't get that hot(650-675) is it worth trying or do I need to figure something else out?

I heated some with my turkey roaster recently and it improved the rock considerably but I feel like more heat would make it even better.  The raw rock was extremely difficult for me to Knapp and was hell on my tools.

Ok I'll give it a whirl and see what happens. If it doesn't work I might just try the ground fire method

I was going to suggest that too.. just hard to determine the amount of heat generated and time frame.. wind , outside temp . ground moisture  how big a fire you build and how long you keep it cooking in the ground all factor into that.. you will need a couple of days of no rain or you will lose that rock.. I've never cooked it I watched a few videos on it and thats how it was done primitive style... good luck...gut

Heat it a second time in the roaster. I cover my rock in the roaster with beach sand also.

I’ve never tried it, but I seem to remember guys talking about using barbecue grill to.
