[TheForge] glass doors

Sun Jun 11 07:18:46 EDT 2006

	Thanks Roger. I know tempered glass is expensive enough (it cost me $350
for three 9 x 32 shelves on a project), and it definitely breaks in all
those little shards.......as in sliding glass doors we've had hit in storms.

Never realized Pyrex was made in sheets........maybe that's what the fellow
that was calling "high heat glass" was refering to?  dunno.

I was talking with one fellow that makes the scandanvian masonry furnaces
that you do fast burns twice a day (morn and eve) then the radiant heat of
the masonry warms the house for the rest of the day.  He said the doors were
about $1500, a guy from Maine builds them and the glass was 1/3 the cost (as
he thought it was ceramic glass) - what that is I'm not sure either, I'm
just starting to research all this stuff. (starting here - then to the glass
supplier that's done my tempered glass for tables and shelf units next).

Ralph

tempered glass meets all codes for firedoors where I live,  it also does not
break in shards, just crumbles like auto glass.  At some point I rely on
reason and common sense,   I do not install mattresses at the bottom of
stairs either.
