Recently I tried a recipe for "fake glass." The recipe was like most I have seen. Anyway, the finished product had all the characteristics of glass except it was yellowish in color. Has anyone else had this problem? Did I do something wrong? How can I fix it? Thanks for any responses.Helix777

What I am about to say is just something that popped into my head, so it probably has nothing to do w/ the color change. The only thing I can think of is if you cooked it too long and it got burnt, or if you put too much corn syrup in (if that was part of your recipe). Corn syrup is the only yellowish thing you put in the stuff, so if it's not that, I don't know what to tell you.

I made some "glass" and had the same problem. i think its that you need white corn syrup. i know it exists but havent tried it. my question is how do you get rid of bubbles? i had little bubbles in mine when i made it.

Just reposting. Also, I would like to add that I used fairly clear corn syrup, so that isn't the problem.

Well not too sure of corn syrup but I think that will always turn yellowish. And I am not sure of KARO brand syrup and what it essentially is (may also BE corn syrup) but it is water clear in the bottle. Corn syrup already has a slight yellowish cast I think. As for "turning" color if you cook it too long it will usually go brown from carmelization (thus that amber color). But the yellow may just be because of what you begin with, having a slight yellowish cast.Getting air bubbles out is fairly easy. Once the glass is poured (if in sheets) and cooled to a solid once again, you can take a small propane torch (standard plumbers tool and reasonably cheap at hardware stores or Wally World) and remelt the glass in the spots where the bubbles are and it will smooth out. Just be careful because you can burn it that way too. Also if you are careful to not stir too much air into it when you are mixing it in the pan, then your bubble problem is greatly reduced. When pouring it up, try to do it from one side and not all over. Pour it into your mold and then tilt the mold so it covers evenly all over but still do it from one corner, end, side whatever. This stuff is effective to use but because of lots of these kinds of problems it can be difficult to work with. Not hard to make - just a pain to get right all the time. GOOD LUCK!! FXMan

I would like to know if anyone knows how to create other things then sheets of glass. Like a beer bottle for instance. and for this would I simply add food colouring or would I intentionally burn the glass until it turns brown.

Westward,Well other "things" will require a mold of some sort. For the purpose of the "candy" glass, since it is so hot, silicone molds might work. Two part molds are usually used that are made of aluminum or some other metal. Even those that are used to pour up the resin that is used for fake glass require metal molds. But as I said, silicone molds backed with plaster or plaster bandages for rigidity should work. You simply have to know how to cast two part molds that can be separated when the "glass" has cooled. With the two part mold process you can just about mold anything - that is anything that can logically be removed from the mold when cast. Good luck!! FXMan
