Hi everyone, I was hoping someone could answer me about the glass on my Avalon Olympic stove. I filled the stove up last night and went to bed and when I woke up I had only coals in the stove like normal. The problem is I also had my glass marked with what looks like an area shaped in an oval in the center of the glass, white in color and finely scratched all over in the oval. This is my third year burning the stove and this has never happened before. I have tried to get the scratches out with ash and glass cleaner to no avail. What can be done or is the glass trashed?
