[Nhcoll-l] Numbers on specimens

Tue Aug 30 01:53:31 EDT 2022

... just to add to Ronald:

there was the very informative presentation of Jacki Whisenant in Edinburgh at the SPNHC Conference on the different qualities of pens (Osteoscribing: writing on bones); definitely worth watching the Zoom recording!

With best wishes

Currently I work primarily with fossil specimens. I would second what Carrie Eaton had said.

I prefer to write directly on the specimen (fossils and minerals) when possible. Ideally there is some matrix that will provide a suitable (unobtrusive) spot.
Use archival products.

Penmanship sample—I will give students and volunteers a blank label and ask them to write down their contact information

Here are the tools that we use

Sakura Pigma® Micron black ink pen
We currently use the Pigma® Micron pens because of the convenience with multiple users. They are available in a range of point size. We have now been using them for more than two decades.

Koh-I-Noor® RAPIDOGRAPH® pens
                        Recommended sizes: 0 and 00
                        Koh-I-Noor® black India ink
This is the best tried and true method. The Koh-I-Noor® ink and pens are the standard. However the pens require a bit of care and maintenance.

for DARK specimens

  1.  We use white acrylic paint to paint a rectangular writing surface
  2.  We use a Sakura white Pentouch® Marker to write directly on the specimen. (The smallest tip size is a bit broad.)

For a clear coat painted over the written number
Paraloid B72 (ethyl methacrylate co-polymer) clear lacquer
(25% solution by weight in acetone)
Note: the clear B72 lacquer may make the Pigma® Micron pen ink run if the ink has not dried completely.

This is a poster that covers the labeling techniques that Carrie mentioned.

We prefer the Paraloid B72 'sandwich' method and have used it on all sorts of surfaces.

Hi Liath,
We apply numbers directly to specimens here – minerals, rocks, fossils alike. Depending on the coloration, surface texture, etc I will use a few different techniques using an archival varnish, titanium white acrylic paint, india ink, and other archival safe products. We use a technique in our prep lab now to keep data with the specimen where preparators will cut out a small piece of Japanese rice paper or archival tissue, write the number on with archival pen, and then adhere this small rectangle of paper to the surface with B72 or B76 (stole this idea from Amy Davidson – thank you!) as a ‘temporary number’ but so far it seems like our temporary prep lab labels have been staying on just as well as the painted/ink ones. My students/volunteers have varying abilities when it comes to writing tiny and/or cleanly so when I find a student who has great tiny writing, they almost always get put on cataloging and numbering for as much as they can stand it. Other curatorial duties (cavity mounts, making boxes, data entry) are then the tasks of my students from whom handwriting is a challenge. It all is helpful!
Cheers,
Carrie

Subject: [Nhcoll-l] Numbers on specimens

As most of you know, specimens often have their old numbers written somewhere directly on the surface of the object. In our collections we do not write numbers on the specimens, primarily because the previous curator didn't want to police the handwriting skills of her volunteers. That makes sense, but I think that we really should have the numbers on there somehow. Some people have suggested printing out the numbers and using some type of glue to adhere the numbers to the specimens. I've seen this done before, but I've also seen many of those labels falling off over time. When I managed mollusk collections, writing directly on the shell surface was usually easy to do, but for my current collections that consist primarily of fossils, rocks and minerals, writing on the surface can be tricky. For those of you who do apply numbers to specimens, what are your thoughts on the subject?
Thanks ---Liath
