[Nhcoll-l] Guata / Watte for curation subjects

[Mariana Di Giacomo]

Hi Sergio,

"Guata" is batting, so hopefully it is polyester batting, although you
should ask just to be safe. For short term transport it is ok but make sure
that if they're using this material for permanent storage, that it is
placed correctly because eggs are so light that they can spring if the
batting is compressed. Another thing to keep in mind is if you have broken
eggs, because the batting can get caught in the cracks, so whoever is
manipulating these, should be very careful. In short, it is an acceptable
material with certain caveats that you should examine for your specific
case.

Let me know if you have any other questions, estoy a las órdenes.
Best,
Mariana
