Velox Lantern Slide Film

For use with the Kodiopticon or any other lantern slide projector that
has a water cell cooling device. With these films you can make lantern
slides by contact as easily as you can make Velox prints, the exposure,
development and printing being the same. For making slides by projection
they are as convenient as any plate.

After the slide is made, it is masked with Velox Lantern Slide Mats and
mounted in the Velox Lantern Slide Frame which has standard opening, and
eliminates the binding of the edges.

These slides are absolutely unbreakable.
