You Can't Break A Window Without Making Some Glass
Wasn't really sure how to tag this one as far as site categories go. Ended up going in to inspiration.
It is a short flick by J. P. Morgan explaining on how to make Breakaway Glass. Breakaway glass is the glass used when you see things break in a movie, like a person going through a show window or that oh-so-common whine bottle on the head shot.
Turns out it takes very little to produce breakaway glass. The film and recipe after the jump.
Recipe
- 2 cups of Distilled water.
- 1 cup of light corn syrup.
- 3 1/2 cups of Sugar.
- 1/4 teaspoon of cream of tarter.
- Add all ingredients into the metal cooking pot.
- Bring mixture to boil stirring it constantly.
- Let it continue boiling on high until it reaches 300 degrees.
- This will take about 45 minutes.
- Spray the cookie sheet with the spray cooking oil.
- Pour the mixture onto the cookie sheet and let cool for at least 1 hour.
- Your glass is finished. Because of the spray oil it will fall right out of the cookie sheet

Breakaway glass
Working with practical effects over the past thirty years it is amazing that people think is a safe option to real glass. Nothing more can be wrong, though this is breakaway glass, it is still glass. Splinters in eyes and other soft tissues can happen with this stuff, like wise in casting if it is not spun correctly large lumps in bottles/vases can form injuring your actor.
The making of the stuff is quite serious, burns/scalds from the mixture is a lot more nasty than with water, this stuff sticks worse than napalm and causes as much damage.
Take care when using this, on set the stunt co ordinator and SFX director are stringent on the use and handling on this material. Even grown men become little children with this stuff around.
Having had umpteen bottles smashed over your head any fragments in your hair is a nightmare, think what would happen in a hot shower a sticky mess. Having jumped through a resin window for a student production and landing on a crash mat and having cuts turns you off this.
Great post, but be responsible

300 degrees kelvin?
A good style also is to mention what kind of degrees the degrees are. Kelvin? Celsius? Or ever the dreaded mesozoic non-standard farenheit of the SI-haters :).
300 degrees Fahrenheit
It is 300 degrees Fahrenheit. We love being non-standard over here...
