The myth of using vermiculite and crockpot or fiber blanket is fairly prevalent here. It is not something that is widely done in ANY other glass community though. You cant rely on it as a method. You may get away with it at times and then at others you will get bitten by it. Full annealing in a kiln is a necessity. Do whatever you have to do to get a kiln up and running. What background do I have to allow me to say this? I have 13+ years of soft glass hot shop experience and 8 years torchworking boro.
