I decided to make the rear window cracked. I’ve already showed you how to make an ordinary broken glass. Now we’ll talk about the tempered glass, that doesn’t really create a spider web effect. It rather cracks into thousands little crystals that stay together if you don’t touch them.
The method is old and well-known, but I’ll remind you:
You need:
-a powder called ice sparkles or similar, I used a product by AK interactive.
-translucent PVA glue
Just put a sheet of plastic foil on your desk. Spread the glue into a thin layer. Then sprinkle it with the ice powder. After you let it dry for a while you end up with a firm, semi-transparent surface. Cut it to the size of your windshield and that’s it. You can also remove some of the glass or make some holes. I found out the best way to do it is not to cut the glass, but rather rip it with hobby knife.
