You can make frit from leftover glass pieces in a few different ways.
First, if you have a torch, simply heat your piece of scrap in the flame until it gets red but not drippy. Then drop it into a bowl of water (wearing protective eyewear, of course) and watch as the glass breaks into tiny little pieces.
You could also choose to use a Frit Piston. Place compatible glass scraps into the frit piston, insert the upper plunger into the tube and plunge. The nice thing about the piston is that it allows you to create frit in any size you want.
Another, perhaps less refined, way to create frit is to wrap your glass in a towel, grab a hammer and have at it. (This works especially well if you’ve had a bad week at work!)
You can also try a good old-fashioned mortar and pestle. This works best with small pieces of scrap or large frit that you want to grind down.
