While cleaning out my oven I noticed that there were some chips in my pizza stone (the one below is about 1.5" long). I would like to know what the impact is, if any, of worn pizza stone.
- What degree of wear and tear is to be expected, and what is dangerous or otherwise the point at which you just need to get a new one? (I.E. Do I need to replace mine for what appears to be such a minor, superficial problem?)
- Is there anything that can be done to repair cracks, or is it even necessary or advisable?
- What would be the impact of those varying degree of wear and tear, be it uneven heat transference or the likelihood of it cracking in half?
