Is this something that I can buy from my local hardware store (or
possibly ebay)? Would I need to be careful about ventilation, because
of glass particles in the air? I think if my glass supplier says to
bring in the sheets, and they can do it for less than £50, I'm tempted
to go for that approach, because I'm incredibly busy ATM, and would
like the glass ground down ASAP.
