My wife just bought some new pyrex baking pans , and the one we want to
use is just a hair too long to close the oven door on - this is a small oven
in a camper . My question is can I cut the little bit off so we can use it ,
or will it shatter like tempered glass ? I have both a wet saw for tile and
wet/dry diamond and masonry cutting discs for my angle grinder . I think the
best choice will be the tile saw ... but I've been wrong before .

This guy is cutting Pyrex tubing.
