I'm curious as to whether or not glassine envelopes are considered safe for storage (either long or short term) or stamps, or anything for that matter. A quick search found a short page with good info on glassine, stating that it can be made for archival purposes, but does this mean all glassine is archival? Or, if not, how do you tell the difference?
