Two-dimensional artifacts should be marked lightly with a 2H pencil in the
lower, right hand corner, of the back side, when possible. Three-dimensional
objects are marked in unobtrusive areas (where they would not be noticed when
on exhibit). Similar types of artifacts should be marked in consistent
locations when possible.
Using a very small brush, apply a coat of B-72 (large enough to write the
number on) and let it dry for at least two hours (otherwise the pen will tear
it, defeating the protective purpose). Write the number as small as possible,
legible to the naked eye. A stationary magnifying glass lamp is helpful. Dry
for two hours, then apply a second coat of B-72 to prevent the number from
rubbing off.
Just to add a bit of further clarification, DO NOT apply B-72 or clear nail
polish to two-dimensional (paper) artifacts before numbering them in pencil!
The idea behind using these products on three-dimensional artifacts is that it
provides a barrier between ink and historic material so the number can be
removed, if need be. This is also the logic behind using a soft pencil to mark
paper artifacts; it can be erased without leaving much of a mark. B-72 or nail
polish will soak into historic paper, leaving a permanent stain.
Otherwise, a very thorough walk-through of how to number artifacts. Thanks,
John!
