Below is the method used to make sugar glass, which is used a lot in the special effects industry to imitate real glass as it is more easily broken and isn't as dangerous.
3 cups of sugar one cup of white Karo syrup (refined molasses)
2 cups of water 1/4 (quarter) teaspoon of cream of tartar.
Mix well and heat to 300 degrees Fahrenheit. Pour into a well greased, slightly chilled mould. The finished product will become sticky to touch unless it is kept cool.
Only has a limited time of use before it starts warping.
