Hello, new to the forums, and BP's in general. (Just got mine on Sunday!)

Anyway, I'll try to ask my question without rambling too much. I just spent a good amount of money, and with my PT job, it left me pretty much broke, I have everything I need, such as heating and junk, but right now I'm just using a small cardboard box and a cleaned out plastic popcorn jar as hides, and want to make my own.

My question is, since we don't have any type of glass or existing hide, is it at all possible to make the mold on a bowl, but take it off before I stick it in the oven? I did read in a previous post that it would be hard to make your own mold from scratch, but I was wondering if it would work to make the mold from a bowl, then take it off, so as not to melt/crack anything we have?

Sorry for the long and possibly confusing question, but thanks in advance!
