I purchased a piece 2x8 3/8 thick tempered for $200what do you guys think one of these sheets retails for btw
How about a see through DIY tank with one sheet of glass on either side (4'-6' plywood ends and 8'x 4'-6'bottom). Now that would be a l\/lonster tank!i figure i might just use one sheet for a glass front on a plywood tank
Good luck!

The tempering is a hardening process of the two surfaces, leaving the inside regular hardness. The purpose is for the hardened surfaces to propagate cracks so that in the event of an accident, there are not 100 ultra sharp knives flying around. The tempering process is done after the glass is cut to order. The only way to cut it again, is to remove the tempering, which requires a glass furnace. And no, your local glass shop does not have one and they can not cut it for you. If you are in a large city with a good glass market, they may take your pane and give you cut plate glass in return.pics of ur 18k pondIt looks like the fact that tempered glass can not be cut or drilled needs another repeatThe tempering is a hardening process of the two surfaces, leaving the inside regular hardness.
