While I do the minor cleaning and repairs needed for the artifacts in the museum’s collection, there are jobs which are beyond my abilities. A professional conservator is required in these cases.
I would first like to clarify that there is
a difference between conservation and restoration. The goal of restoration is usually to bring
an object back to its original appearance.
The goal of conservation is bring the artifact back to a stable
condition. Though improving the
appearance of the artifact can be one of the objectives, it is not the main
one. In some cases, conservation of an
artifact can result in leaving evidence of wear, or other “imperfections”. Preserving the artifact and its history is
the main goal here, not appearance. Additionally, unlike
restoration, any conservation work done is reversible.
We are very fortunate at the NMCWM to have a volunteer who is a retired conservator and who can occasionally donate his time and talents in working on some of our artifacts. He was recently able to stablize a surgeon's leather field case for us. It was affected with red rot, and was displaying the characteristic powdery-red surface and weakened areas.
The case not only looks much better, but it is now stronger and less brittle. Though the red rot did do some damage, the case has now been stabilized. |
Another artifact which had professional conservation work done on it is the commission pictured
below. The document was in fair
condition when it was acquired. It was
somewhat yellowed and faded and had some surface dirt, and it had been stored folded
for many years. The document was weak
along all the fold lines, and one segment was completely detached.
This detail photo shows damage along fold lines. This is a good reason to store paper items flat and unfolded! |
The commission
was sent to Cleveland Conservation of Art on Paper. The conservator reported the treatment as
follows: The surface of the paper was
cleaned in the non-image areas, using grated polyvinyl eraser crumbs. The paper was immersed in deionized water
conditioned to a pH of 8.0. As a result,
the paper became lighter in color and the acidic content was lowered. The back of the paper was sprayed with a very
light alkaline reserve spray of magnesium oxide. This will help to keep the acidic content of
the paper lower. The tears were mended
and the weak folds were reinforced with kizukishi conservation paper and zin
shofu wheat starch adhesive. And
finally, the document was placed in a stable, archival quality paper folder,
which will allow the gradual migration of acids out of the document and into
the folder paper while it is in storage.
As you can see in this photo, the document is now in much better condition than when we received it, and is much better preserved for the future. |
It is amazing
what can be done for these artifacts! It is fascinating to me, and I
have to admit that if I had to pick another career, I’d definitely look
into the conservation field.
