Jim: Here's a neat source for restoration-quality glass floors such as we
have been talking about:
Circle Redmont in Melbourne FL 800-358-3888
Re polishing glass: a couple of years ago we installed a 4x8 pane that had a
pass-thru circular cut-out. It got scratched somehow during installation,
and rather than replace it, we polished it out with tin oxide, water, a
power-buffer, about 3 hours and a bit of a mess.
