Dear Alexandru,
Regarding the use of acetone, I would also suggest to have a look at
this research:
Experimental taphonomy in museums: Preparation protocols for skeletons
and fossil vertebrates under the scanning electron microscopy, by
Yolanda Fernández-Jalvo & Maria Dolores Marín Monfort. Geobios, Volume
41, numéro 1, pages 157-181 (janvier 2008).
Best,
Mariana

> There would be another question regarding defattening using acetone. The problem comes from the fact that acetone may be difficult to find in a pure chemical formula due to the regulation concernig dangerous and hazardous substances. As I asked my colleagues in chemistry department, it is possible to get some (limited quantity- 1-2 liters maybe), and they will give me 99.9 %purity acetone. I imagine this is not the concentration most of you use...so here is my question..what's the ideal concentration for acetone solution? what's the procedure for re-using (cleansing) the solution after one series of defattening?
