I've broken the ceramic glass on my wood stove, and replacements are expensive and have long lead times. I'd rather not rely on my backup furnace for the majority of the winter.
I have a pile of leftover printed porcelain tiles from a bathroom renovation. I have the tools to cut them and they are large enough to fill the space. They're free and cheap to replace, easy to cut to size, and I don't care about visibility into the stove since it's hidden in a corner anyways.
Porcelain seems to be able to handle the heat just fine. Is there any reason I can't do this as an alternative, or at least in the interim while waiting for new glass?
