I'd have to go with Steve's conclusion that if moisture got a foothold anywhere in the surface, the freezing would cause it expand and break the disc or wax cylinder. Especially if the records were never touched. Unfortunately, I don't believe dessicant would have helped in a severly cold atmosphere as the moisture has to be part of a warm atmospheric environment to work.

As long as critters are kept out of them and they remain dry, they never audibly degrade !! At least that's my experience. Of course, cold shellac or wax is extremely prone to breakage due to brittleness !! Double that for wax amberol cylinders !! The dessicant would be a good idea for wax cylinders. But then I wouldn't store wax cylinders or shellac anywhere where I myself could not live !!

I suspect that it will be important to know two things: what sort of material (cylinders, 78s, lacquers, LPs, ??); what sort of storage environment.
