Reply #2 Urgent:dried out specimens
|From:||Gayle Callis <firstname.lastname@example.org> (by way of histonet)|
Interesting, there must be some variations to Ruffers, my recipe came from
a archeologist/pathologist, and he didn't use formalin. His recipe came
from Armand, 1914 - 1915. I guess variations do exist.
5 parts water
3 parts absolute ethanol
2 parts 5% sodium carbonate
Treat 24 - 48 hours, then go to absolute alcohol.
We watched a piece of mummy lung reconstitute during the workshop, amazing
to see it regain normal size as it rehydrated.
Formalin makes sense though
