If you buy the flat glass from an on-line vendor, buy the glass setting tape from that vendor, too.
Thicknesses of glass and tape are sometimes different from different sources.
When you buy flat glass from a local vendor, take your old glass in - not just for the pattern, but also for the glass thickness. If they cannot match the thickness, you might hasve to try different thickness of setting tape (if you choose to use setting tape).
