[Nhcoll-l] Request for plant exudates: modern materials, copal, or amber

[Jorge A. Santiago-Blay]

Hello:



Plant exudates are generally sticky organic materials that many plants
produce (http://essential.metapress.com/content/1110865105v7q345/). With
time, they tend to become solid. One kind of plant exudate is resin;
fossilized resin is known as amber (
http://essential.metapress.com/content/x117340n1t081165/).



Does your collection hold any one or more of these types of materials?
Typical departments where these materials are held include, but are not
limited to, are: botany, anthropology, and mineral sciences. If “yes”,
could you contact me (blayjorge at gmail.com) or Dr. Joseph B. Lambert (
jlambert at northwestern.com)? We use small samples (100 milligrams,
approximately the volume of a new eraser on top of a pencil) of plant
exudates, copal (partially fossilized resins), and amber with excellent
geographical (and in the case of copal and amber) geological provenance.
Some of these materials are used in archaeological contexts (
http://essential.metapress.com/content/339j6785701j146h/), thus samples of
such materials would also be appreciated.



Gratefully,
