heat treating?

[boughnut]

I have alot of flint that needs some heat treatment.  I have no special oven will a fire work with lots of hot coals or my regular oven?  What is the best way to do this with out some type of potery kiln?

It can be done with a fire, but it is very tricky. If it is not done properly you will burst a lot of stone making it useless. An oven will work, but you are heating a lot of extra space. The easiest, & most affordable way I know is with an electric Turkey roaster. Since moving into town that's the method I use. I prefer a fire pit, but its just not doable. The roaster is quick,simple ,& works great. The only downfall I know of is they only go to 450 to 500 degrees.  Tower

WOW!  That coral is almost too pretty to be busted into gravel!

Yes Sir! That's why when you find an artifact down here made from it, (preferdly a Newnan, or Hillsborough) they are worth a few thousand dollars a piece.

Looks like a great Idea I have an old broke down grill I am going to turn into something similar to what you have there.  I tried heat treating in my oven once and when I got to chipping at the stone it was all cracked up and fell into pieces.  Hopefully I can get it right this time.  I have made many obsidian points and some flint from slabs and a few from spalls so this will be a first should I spall the stones out first then heat or leave them hole I have also seen on youtube where guys soak them in water till they are ready to start flaking is this also a good practice to use?  Thanks for the info guys and those are some beautiful stones.  and if it makes a difference in answering my questions I will be heating flint.

I use a slow cooker with the insert taken out.  It's used just like the turkey roaster, but doesn't get as hot.  Still works though.
