[Nhcoll-l] fatty dolphin

[Marta Pérez Azcárate]

Dear Sergio,
I strongly recommend that you contact the right professionals. In this
case, they would be conservators (not taxidermists). In this way you will
ensure that the works follow the correct criteria and standards, like:
- Respect for the aesthetic, historic and scientific significance and the
physical integrity of the specimen.
- The use of only products, materials and procedures, which will not harm
the cultural heritage, the environment or people.
- The action itself and the materials used should not interfere with any
future examination, treatment or analysis.
- They should also be compatible with the materials of the cultural
heritage and be as easily and completely reversible as possible.
Best regards,

Marta Pérez Azcárate

> The specimen is a very old one, because it appears in a 1850 catalogue. I
> don't know if in those days taxidermists use paints.

> William Sheperd: we can try to obtain an spectrometer to know what kind of
> product is the "grease". It's a good idea. I don't think that the grease or
> fat is due to changes in the temperature or similar. Specimen was stored in
> same conditions last years, and people who knows it since 50 years, they
> always remember it as "greasy".

> Steve Halford: A local taxidermist wants to apply Borax to remove the
> grease, but I don't want to apply anything before a good data collection.
> As you say, solvents are unsuccesfull.
>
> Julian Carter: Yes, we can try to clean the basis. As I commented before,
> basis could be valuable due to it's age. Wood restoration could be

> Giulia and Marta, I send you a mail with the data you asked for.
