Any tips, aside from using a wet saw, on how to cut 3/8" plate glass (not tempered obviously).

I've only cut glass up to 1/4" thick. This glass is reclaimed from an older tank that had a crack in it. I'm salvaging the glass to make a custom sump with (ie, it's free glass).

I've tried twice to score/snap it and it just doesn't work. It breaks at random, sometimes following the snap, but always wandering off.

Cutting tool is brand new, and I've cut lots of thinner glass. This stuff has me beat.
