I'm rebuilding my batch box and would like to put a window on the top.
I'm contemplating buying a plate of neoceram so I can be sure the glass will be able to withstand the heat.
How does one go about mounting glass to cob and/or brick? I assume you can't simply bury the edges in cob and not expect it to crack. Does anyone have any detailed pics of how they mounted their windows?

I don't think I have any good photos, but actually, I do indeed simply bury the edges in cob. Works just fine.

Are you using neoceram or some other type of glass?

I think so. Schott Robax is the brand.

Like Matt said, just embedded between two layers of cob. No cracks in glass or cob up to his point.

I suspect the cracklessness is because the cob tends to shrink away from its perimeter as it dries. And once dry it does not move much at all with the thermal cycling. I folded a layer of 1/8" ceramic felt around the glass edges in the one that i did. Was just being cautions...
