So I am trying to make an edible fish bowl that my rice krispy and fondant fish will sit upon. My first trial attempt at sugar glass worked fairly well at first. I used the sugar, cream of tartar, and light veg. oil recipe, and it worked well. I burnt the sugar a little so the blusih bowl became green, something I will have to watch for my next attempt. And I had the bowl out on the counter to see how long it would last in Florida humidity inside my apartment, and itslumped in about an hour.
The problem is the bowl will be on display inside of a building for 45 minutes, and then will be placed outside to be judged by the public. Does anyone have any hints or tips that could help me make sure that my bowl dosen't end up looking like an ashtray made in a kindergarten pottery class?
Also what would be the harm of filling the bowl with cooled blue gelatin to look like water? Would that increase the rate of water absorption, or would it mitigate it since it would be pulling it from the jello more than the air?
