[Nhcoll-l] Skulls and cleaning

[Sergio Montagud]

Hi Paul,

Dermestids is a good idea, but now we have no space and conditions to rear them. I dream to have sometime a Dermestid camera, but the things here aren´t in this way now.

Thank you!

Sergio

Dermestids? They work well with fish skeletons. Set them up in a lidded plastic box somewhere sheltered outside and let them at it.

External.

Hi Sergio,

I used to use sodium carbonate (10%) in hot water, which worked quite well with a bit of scraping; try not to boil as that 'fixes' the flesh.  There are   other fleshing crystal products around but no-one will reveal their composition!  They are gradually deliquescent if that might give someone a clue as to their identity - they work even better.

With all good wishes, Simon
