Antique from the1880's - Glass Tank Slide for Magic Lantern Projector -
This was used in scientific demonstrations of chemical reactions during a magic lantern projector presentation. It's a good example of how the lantern was used in educational / institutional settings for learning.
There are two square pieces of glass mounted in this heavy wood framed form (with cavity/tank). The glass squares are separated by a space with a liner of india rubber (looks like a piece of tire). When chemicals are mixed inside, their reaction can be projected on the screen. One example would be water mixed with litmus and then the colors change. Add more, like dilute acid and the color changes again (blue to red) etc. Since it's a top only opening, best suited to projectors with an open type slide stage.You have probably never, ever see one of these on . Rare historical / collectable piece of Magic Lantern History.
