I have a bottle of confectionary glaze that I bought about 2 years ago to shine up a wooden floor for my cake scene.  I didn't like the smell and was concerned until I read a post on here that says it supposed to smell like that.  I really liked how it made the floor shine!!  I never used it again but now I have a need to use it.  Does anyone know if it goes bad?  I don't see an expiration date on the bottle and I hate to buy a new one that I may not use again for...
