Recook?

These pics are of mostly OH flint ridge stuff, but also some Texas stuff bought off of ebay.  You can see what the stone did to my brand new copper boppers.  And now I can't get much of a flake off without shattering the whole stone whether I use the boppers or my hammer stones.  The deer antler won't do anything at all and my copper punch takes flakes that at best travel 1/4" but generally less.  I certainly can't get any flakes to push to the middle of the stones at this point.  I was thinking that maybe the cooking helped soften the outer layers of stone and as I flaked that away the remaining stone has maybe gotten harder...?  Would that fit with others experience?  I held all this stuff in a turkey roaster overnight at about 200 and then over the following day worked it up to 450 and left the stones there overnight.  Unplugged in the morning and allowed to cool.  I only had one nodule of Texas stuff that was fractured beyond use. 

How likely am I too overcook this stuff if I repeated that process?  I thought I might do the turkey roaster like I have been and then take them into a preheated oven in my kitchen and push them up to 500...?  Bad idea?

It doesn't appear to me that you overcooked them yet. I don't have any experience with Ohio stone. I have just a little experience cooking period. If it overcooked it becomes very brittle and just fractures into pieces. I'm thinking you might need more heat but not sure about the moving to preheated oven. I'm pretty sure some guys use charcoal grill to. I e always just done like you did. I usually start more conservative and if it's not enough get more aggressive. Maybe someone else will give you more specific advice. Good Luck from here looks like some nice stone with some fantastic platforms. Maybe a bit on the large side yet for cooking

That looks like some pretty stone! I want some >:D

Sasquatch:
To answer your question.  There is no such thing as Recooking,  If you dont see a change essentially all you did was get heat the stone up.  It has to reach a certain temp before it solidifies more.  Different rock different temps.  So because you have already dried the rock out you can go pretty quickly up to temp without blowing it up.

If you want to use your stove you can, just unplug it carry it outside and away from the house to protect family from toxic gasses, make sure you have replacement glass for when rocks blow up, and don't worry about bringing it back in because there will be nasty smell in the food from then on.  >:D    SOOOOOOO.... DONT USE IT.   
But it is up to you...
