Last year, when I started baking breads and pizzas on the eggs, I used my wife's Pampered Chef pizza stones. I had heard the PC stones were prone to breaking if the temp was too high. So, we were careful to keep them below 450. (And, yes, this was done with my wife's full knowledge and approval!)
I have now purchased BGE pizza stones for both eggs and will no longer use the PC stones in the eggs.
Now, for the question. Both PC stones are black from using them on the eggs. That part we don't care about. But, they have lost their "non-stick" abilities. How can I get this back.
One thought was to do a good high temp burn with the top facing down towards the fire - just like when I have cleaned my platesetters. Hopefully, this will bring it back to it's new condition. But, I am afraid of the direct high temps.
I've got to think someone else has experienced this. Any thoughts would be greatly appeciated.
