Because of their delicacy, some of the beads have lost parts of the carvings. My question is as follows: Since bone tends to dry out and this drying out would make these beads more fragile, is there something (oil, wax, etc.?) that I can apply to the beads that will protect them from further dessication and preserve them?
I wonder if PEG (poly ethylene glycol) which is used to preserve
wood might do the trick? With wood, you soak the newly cut wood in it
and it replaces the water in all the fibres with a soft plastic which
stops the wood from ‘drying out’ and distorting. Other than that,
maybe a wipe over with white beeswax would be appropriate.
