You've seen greenhouse glass cut on the telly a million times. After all glass is glass, whether it's in the roof of a glasshouse or the window of a house.
The villain puts a suction cup on a window. You can hear the scratching noise made by the cutting tool as he - it's rarely a woman - drags it around full circle. And then, hey presto - the perfectly cut round piece of glass magically pops out.
Except that it doesn't work like that. If you tried to pull the glass out the way they do on TV or in your favourite action movie, you'd not only break the centre piece, but you'd break everything else as well.
Why is that?
In this brief post, you're going to find out why; but to do that, you'll need to know how to cut greenhouse glass in the first place.
Safety
Before you get started, make sure that you are wearing gloves that are designed for handling glass. Not only is greenhouse glass extremely sharp, it's also slippery. You don't want to drop it.
