cracking crab carapaces
Cracks caused by changes in humidity

Excluding air and water from pyritic specimens. Silica gel acts as a dessicant.
Preventing pyrite decay with silica gel


pyrite alteration leading to disintegration
Crumbling though chemical changes


silverfish demolish many old labels
Attack by silverfish


Total collapse of the specimen following internal decay.
Disintegration of specimen


The number is just fine..but where is the specimen?
In this case, the number has lasted longer than the specimen!
