Staff officer buttons are two piece with a rim that held the dome
and back plate together. They were more ornamental and therefore more fragile
under battlefield conditions. The standard enlisted men's uniform buttons usually
held together much better in combat situations because of their flatter
profile.
The artifact sustained damage from both the battle and from the corrosive effects of metal being buried for a long period of time.
The same button probably would not have been identifiable if it had
been left in the ground for much longer
The uniform button has now been cleaned and stabilized.
However more work still needs to be done. With proper care, it and the other artifacts represented in this exhibit,
will tell their stories for centuries to come.
Note: If any of the
readers, have any old metallic items, please understand that the idea is
to stabilize the artifact, not to "shine it up". You never want
to destroy the patina, just remove the corrosive salts.
If the artifact is not too delicate it can be
boiled in distilled water in successive treatments until all of the
corrosive salts have been removed. I've done this as many as ten times or
more, discarding the distilled water along with the leached salts each time. The
artifact is then cleaned and sealed with a special micro-crystalline wax that most
museums and conservators use for this purpose.
