Cutting Thin Stained Glass Strips Expertly

One of the more difficult stained glass cutting tasks is cutting small strips without snapping the ends off. Cutting straight lines when they’re very close together can be tricky too if they’re very thin strips. It’s easy to crack the narrow strips of glass and get a poor cut.
This video shows you 3 different methods to help you  improve your stained glass cutting so you can cut these thin strips successfully.

Cutting Methods for Straight Narrow Strips

  • Mark the glass and place a ruler over the cutline.

  • Make sure the cutter head is in contact with the ruler for the whole length of the cut. This will ensure that the line is straight.
  • You can either pull or push the cutter when you’re using a ruler, whatever is best for you. I prefer to pull.

  • Using a pair of grozer breaker pliers, gently put downward pressure on one end of the thin strip. Make sure you keep the flat jaw on the top, lined up with the score.
  • If the glass doesn’t come apart with gentle pressure, try easing it from the other end and move along easing it apart as you go.

  • Start easing it apart at the end rather than the middle. This reduces the chance of a flare and also allows it to run the whole length of the score.

Cutting Pointed Narrow Strips of Stained Glass

  • If the glass goes to a point, start breaking it from the widest part with the grozer breakers.

  • If your piece glass is hard to break apart from just one end, open it at one end by exerting pressure with the breakers until you hear a click.
  • Then repeat this at the other end and it should come off in one thin pointed strip.

Cutting Stained Glass Strips From A Narrow Piece of Glass

  • This is tricky as the narrowness of the glass means that you can’t easily hold it steady. One pair of grozing pliers doesn’t work because you can’t hold it securely enough with your other hand.
  • Use 2 pairs of pliers to hold the glass. Use the grozer breakers to snap and pull the glass apart as normal.

  • If you don’t have 2 pairs of grozer breakers you can use a regular pair of pliers.

You can use this same method for cutting pointed strips from a narrow piece of glass.

Just gently ease it apart as you did with the straight strips. You don’t have to rush, you have to feel the glass as it’s ready to break and there should be no problem.

These are my recommended Grozer breaker pliers  (affiliate) They are available on Amazon through this link.

More Cutting Pointed Strips Methods

Here are some more suggestions for cutting stained glass that goes to a narrow point. They’re kindly offered by my online students. Try them all and see which works best for you 🙂

  • The ‘Towel Method’. After you have scored your piece, lay the piece scored side down on a folded tea towel. Fold the towel in fours, then using the metal end of your pencil cutter, gently tap along the score line starting at one end and going to the other end. Works for me every time.

  • When I have sharp points I cut the pointed ends just a fraction of an inch away from where the finished piece of glass needs to be. That way I have a little space for those times when the point may not break correctly. And to give myself a little wiggle room I cut a little wider on both sides of the point and grind the excess off.

  • Start from the point first when opening out the score.
    Rich Alfieri
  • Cut the glass about an inch away then score it closer then score the actual piece. Use the Siberschnitt breakers, turn the rubber piece to the direction of the score line and gently push on it so you hear the glass crack in the middle and on both ends.
