Hello, Greg. Special Collections at the University of South Florida has a helpful summary of how these glass lantern slides are made. www.lib.usf.edu/special-collections/about-lantern-slides/ A number of glass lantern slides have been digitized and are available online for the Soil Erosion and Conservation on the Southern Plains Collection. library.okstate.edu/search-and-find/collections/digital-collections/soil-erosion-and-conservation-on-the-southern-plains/

Mine are solely on glass and pretty thick glass. Some are in color. Any idea what age they are?

Hello! Here is a resource from Oregon State University that may help you narrow down what you have or at least point you in a direction for your research. guides.library.oregonstate.edu/earlyphotoformats/home Here is a book I found from our catalogue that also may provide some insight okstate-stillwater.primo.exlibrisgroup.com/permalink/01OKSTATESTILL_OKSTAT/16c9pn6/alma9938952623202681
