Thank you Tania!

Unfortunately, the bag is not numbered, and I have not as yet connected it to 
any provenience information.    I think it may have been a protective cover for 
another object (the bag is oddly shaped, and appears to have been custom made 
to hold something like a pipe). If so, the object most likely was catalogued, 
and the bag set aside.

Subject: Re: [PestList] Frass and damage on horn button

You don't often get email from tcol...@nhm.org. Learn why this is 
important<http://aka.ms/LearnAboutSenderIdentification>
Hi Nancy,
Do you know approximately how old the button is?  Casein, a milk protein, was 
used to make buttons in the early 20th century.  I am guessing that casein 
might be vulnerable to dermestid attack as well as horn.

Hello--  we're cleaning and processing some collections that have already been 
through a freeze cycle.    One item (a fabric bag with a button closure) has 
buttons that are seriously damaged, and residual frass.   I've tentatively 
identified this as a horn button, and my guess is that this is damage from 
dermestid larvae.  Wondering if anyone might be able to confirm that, or 
suggest another culprit?

(note-- the fabric is not damaged)

Thanks very much!
