Lantern slide or 35mm slide transparency?

[Nicola Mayer]

Hello 

I'm seeking some advice around terminology. I've come across a few 35mm colour slide transparencies sandwiched between two pieces of glass and taped - from the 1950s. Has anybody seen anything like this before, and if so - would you call them lantern slides or just slide transparencies (mounted in glass or encapsulated in glass etc)? 

Best wishes

I have a large number of transparencies mounted just like this, inherited from my Grandfather.  I just call them slides.  My Grandfather, S.D.Jouhar, was among the first UK amateurs to use the Kodacolor process – this had been introduced to the American market in 1942 but had not become available in Great Britain until 1958. He would process the film himself, and then cut the roll of developed transparencies into individual pieces and then mount them between glass.

Hi Kelvin - thank you for your reply. I'm glad to hear these aren't anomalies

I also have some slides mounted thus, in my late father’s collection. He worked at Kodak Research labs and will have mounted them himself, perhaps at work for some project. I suspect that he wanted them really flat for projection, and perhaps at the time couldn’t get hold of commercial glass slide mounts at the time. When did GePe and others start selling such things?
