[Nhcoll-l] Guata / Watte for curation subjects

Wed Oct 6 12:48:18 EDT 2021

Thank you very much, Mariana and Paul for your answer. The link of Byne’s disease is very interesting.

And yes, we will be careful with the batting and the eggs. I presume this methodology is better than to keep them as they are, in a wooden tray with cotton!

Thanks again!

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

Hi Sergio,

“Watte” is the Japanese word for cotton wool, so I think it’s an international term. If they are using polyester batting (sold for stuffing pillows, toys etc.) then there’s no problem. Short-term use of cotton wool is also OK, but it is not suitable for long-term storage in closed environments as it is cellulose and can thus (theoretically at least) cause “Byne’s Disease” in calcium compounds.

External.
Hi everyone, 

Yesterday, a company that helps us to transport specimens for a coming exposition, come to the museum to prepare all the material. I help them in the process and when we want to arrange a large box of bird eggs, I see they wanted to use a thing close to the cotton to ensure the samples. They told me that that material was "Guata" (I think watte in English), and I can use it extremely well to ensure individual each egg on his box. My question is if anybody has used this material in his museum work and if somebody knows negative effects for the specimens, such as acid components in the fiber that can damage thespecimens or something like that.
Thanks for help!
