Thanks to the group for all their valuable input.
However, I don't recall any discussion about controlling the defrost cycle. Are there any special considerations? Off hand, I can think of the possibility of mold growth if an object is kept double wrapped in polyethylene after defrosting, despite being wrapped in tissue paper. Am I overly paranoid? Just how long should a controlled defrost take? Must the object be removed immediately? If not, how long can it go heat sealed in bags? It's not like anoxic treatment where a piece can just be kept inside its polypropylene bag forever. Any input?
