Sugar glass (also calledcandy glass,edible glass, andbreakaway glass) is a brittle transparent form ofsugar that looks likeglass.[1] It can be formed into a sheet that looks likeflat glass or an object, such as a bottle or drinking glass.
Sugar glass is made by dissolving sugar in water and heating it to at least the "hard crack" stage (approx. 150 °C or 300 °F) in thecandy making process.Glucose orcorn syrup is used to prevent the sugar from recrystallizing and becoming opaque, by disrupting the orderly arrangement of the molecules.Cream of tartar is also used for this purpose, converting the sugar intoglucose andfructose.[2]
Because sugar glass ishygroscopic, it must be used soon after preparation, or it will soften and lose its brittle quality.
Sugar glass has been used to simulateglass in movies, photographs, plays[3] andprofessional wrestling.[4]
Sugar glass is also used to makesugar sculptures or other forms of edible art.[5]
