The latest batch of glue granules I got seems to grow mold faster and in bigger variety than any I've had before. I can't let it go 48 hours between reheating without getting a carpet of aspergillus and penicillium.
So this got me wondering whether it would cause any bad issues if I were to make up canning jars with reasonable amounts of glue in them to quickly melt and use and then autoclave them in a pressure canner to sterilize the glue and jar.
Will heating the glue to 240-250 F for ~20 minutes degrade it in any significant way? Knowing what I know about collagen I wouldn't think it would be a problem, but does anyone have hands-on experience? I'd worry about making joints that appeared fine initially and then failed down the road. I've tried boiling and that doesn't seem to create any apparent loss of strength, but it's also not fully effective at sterilization.
I'm mostly gluing leather to wood in organ work, not a high strength requiring application.
