One of the things I found fascinating at McMath is the slide cabinet. There are several hundred original glass slides (emulsion on glass). From what I can tell, order these are from the late 30’s and early 40’s.
The problem is that they were mounted using paper tape and over the years, cure humidity and heat fluctuation has destroyed many of them. I’m going through them to find those that are in the best condition, order and stripping off the disintegrating tape, resealing them with metal tape, cleaning them, and eventually photo archiving them.
This is a tedious labor of love at this point, which I look forward to working on at every chance I get. I am discovering some amazing slides. The projector for them is upstairs and I think we’ll have a blast seeing them displayed.
Current count of repaired and preserved slides: 20
