For tortoiseshell, avoid any type of freezing as this will trigger
layer delamination and cracking  I would suggest the use of anoxia
ensuring that the nitrogen is moistened to about 55-60% RH.

Dried areas of shell are successfully treated in the Antique Trade
using a vegetable oil--non-aromatic almond oil, although some may
blench at using a vegetable oil for treating an animal product.  If
this is deemed to be unsuitable then there are other products
available from taxidermy companies, e.g. Snowdonia Taxidermy.
