Candy Glass Windows

To make candy glass, heat three and a half cups of sugar, two cups of water, one cup corn syrup, and one quarter teaspoon cream of tartar in a heavy pot until it boils. As it reaches the boiling point, most of the water will disappear, creating a very dense syrup. Continue boiling the syrup until it has reached 300 degrees Fahrenheit (148 degrees Celsius) and then pour it into a mold. Be aware that candy glass is brittle, so it is not a good idea to make a single sheet and try to cut it.
