3 Best Times To Tap When Cutting Stained Glass
Do you ever wonder what that ball on the end of your glass cutter is for?
The ball is used to gently open up a score line from underneath so that you can prise the glass apart. It’s a very helpful technique for certain situations.
Tapping is good for:
- Cutting inside curves
- Any score lines that don’t separate with thumbs or pliers
- Cuts that are narrower at one end

Opening A Score By Tapping – Intermediate
You can see from these videos that the tapping method is extremely useful in certain circumstances.
But what about the times that cutting glass by tapping is not the best choice of technique?
The tapping method is not good for:
- Routine cutting and breaking.
It is far better to use your thumbs or either cut running or grozer/breaker pliers than to resort to tapping all the time.
This is because tapping will create an uneven edge that will then need grozing or grinding.
- Very narrow strips.
It is difficult to use the tapping method when the score is very close to the edge of the glass as you can easily break the strip by a misplaced tap.
You would be better off using the breaking pliers to snap and pull a strip apart.
