My friend has a relative in Italy with a box of 40 yr old glass slides. Anyone heard of this and have any information?

I bought a box of 25 of the aluminum ones in the 60s. They worked well in a Carousel projector.

What you show are called super slides. Super slides are used to hold 120 size film (120 size film) and are quite out of the ordinary. The gray framed mounts look like Gepe mounts, these are some of the best quality slides. The white side goes into a projector facing the light source, while the gray side faces the direction of the projection lens of the projector. With the Hasselblad camera there were magazines that framed this sort of film giving more than the usual 12 exposure length of 120 size film, this magazine was designated S-16 for the large mounts that allowed 16 frames to be made on a roll of 120 film.

I had a 2.25 square format camera in the mid 60's. Glass slide mount kits were available to purchase (not cheap). Purchased a special projector for the format. Had to mount each slide and hopefully get a good seal. After many years, most have been ruined by moisture and other things that attacked the "seal". I live in a "dry climate" of Arizona, so the humidity factor should not have been a problem. Most of the slides (memories) are gone . Totally a waste of time and money.

Indeed, there were slides in several formats. I can remember slides being made from 120(620), 127, 828 and 4x5in film. The latter were always glass. I have a few 4x5 in slides of technical subjects.

My Dad was strictly a medium format guy and used a Ciroflex. After he passed, I inherited several cases of slides just like this. Thankfully, my mother did the difficult task of culling before finally giving them on to me.

Those slides ranged in age from fifty to seventy years. Luckily, I still had a projector to view them as they were intended to be seen. Unfortunately, the colors had started to seriously degrade, so a little at a time, I de-laminated them by removing the metal frame and then carefully separating the glass to liberate the transparencies. What a tedious job that was. It took me several months to scan, crop and color correct the slides, but the effort was worth it. I was able to save many precious memories.

This is the first time that I've encountered anyone who was the least bit curious about these rather unique items.

I used thousands of sprocket hole-registered 2"x2" Wess glass slide mounts during my multi-image slide show production days in the 1980s.

Wess Mounts were a pain in the neck, quite literally, as you had to clean two film surfaces and four glass surfaces before they went into trays for a major corporate presentation! However, they DID keep the film perfectly flat in the projector gate, so you could align multiple projectors on the same screen area and project computer-controlled animation sequences, among other things. We regularly used 6 to 12 projectors to blend multiple images on the same screen area.

Slides stored in glass mounts did not last as long as slides in paper or plastic mounts, primarily due to mold growth here in the humid South. My Kodachrome slides stored in polyethylene/polypropylene sleeves are pristine. Almost all my Ektachromes and Fujichromes are severely faded and color-shifted, due to unstable dye layers.

Yes, super slides for 120 film. I had some way back when, like the late 50s and 60s. And I had a special slide projector for them too.

Time that you enjoyed wasting is not wasted time.
