Scratch, tap, and snap

Pictured here: Scoring a hand blown glass plate with a diamond-tipped scoring tool

It can seem like magic to those who've never seen it done before.⁠ Cutting glass with a score line is one of the first things I learned as a glass student...but it remains one of the most essential in the beginning stages of anything I do in my studio.

Before we take our glass to be cut at the waterjet or diamond bandsaw, we must slump all of our hand blown glass plates to ensure that they are completely flat. This allows more precision in our line of contemporary jewelry. And in the slumping process, we need to cut plates in half or quarters like a game of tetris.

This method invlolves a diamond-tipped scribe that allows us to score the glass on one side, which forms a fault line in the plate. Then we just tap the plate on a table edge and the plate separates into two pieces! Check out a video on this process here.
