Your stove just had cheap glass. Pyrex or other glasses will not stand
up in wood stove use. You need to buy custom high temperature panels,
which are expensive but will last forever. Neoceram or Robax are a
couple of brand names. They are marketed as "stove glass", but are
actually transparent ceramics.

It's custom shaped, AFAIK the only source is the manufacturer. And I've
heard from others that a 5 year life span is not unusual in that it becomes
pitted so it's no longer transparent.

what happens is in the first 3 hours any residue that is on the glass not
removed will become etched in the glass.

Look for it in stove shops and hardware stores. NEVER use Windex or regular
glass cleaners!

I"ll have to look for that. The current glass is pretty badly clouded. I
even tried scraping it with a razor blade. Cleaners. Steel wool. Even a shot
of carb cleaner. Nothing made any difference. It's not carbon or creosote
buildup, that stuff came off pretty easily. I talked to the manufacturer,
and they and the wood stove place down the street both say it's not uncommon
for the glass surface to pit over time so that it takes on the appearance of
waxed paper. Wood ash is caustic, and I understand that they can etch the
glass if the glass isn't kept clean.

I'm wondering if something like this can be avoided by just keeping the
glass clean?
