Glass circles can be cut easily with basic stained glass equipment. It's true that you can buy expensive circle cutters to help you - and they do work - but this page will show you how you can cut perfect circles with just a cutter and a pair of grozer/breaker pliers. Not even a grinder.
Before you start with this circles tutorial, you will need to be confident making a cut line with your cutter. If you haven't done this before, then this page will take you carefully through the process.
Take the fear out of circle cutting with Milly's 6 minute tutorial
Making first circles cut
Using thumbs to open score
Separating the scoreline with thumbs
Repeat 1-3 on the other side of the circle. These alternative methods are good if your thumbs aren't very strong.
Using grozer to press on cutline
The handle of the breaker/grozer pliers can be used to press open the scoreline
The plier jaws can be used for separating the glass:
Use breaker/grozers for easing artglass apart
Now for the trickier bit - the two sides. You don't need to turn the artglass over and press the scoreline open for this stage.
Using grozing pliers for smaller bits
The breaker/grozing pliers leave little 'nubs' of glass which have to be removed. This is done in two ways, and you will probably need to use both.
Removing tiny shards
If the tiny shards are big enough for you can get a hold of with the grozing pliers, you can snap them off, as in 5 above.
If they're stubborn, more rounded nubs that are making the edge uneven, you need to to 'groze' them away.
Grozing circles edges
And there you have it, a perfect circle. And all without using an expensive circle cutter :)
