Please reply to the list.  We have a group of early 20th century lantern slides, and I have similar concerns.

We have a wonderful collection (approximately 2300) Glass Magic Lantern Slides that were taken by a local resident 'Comrade Smith' in the mid to late 1800's.  There are both black & white and color slides. We are considering a project which would require scanning the slides with a scanner that has the adapter you place on it and the slide is lit from the back. 

My concern is how this will effect the slides.  I have gone through the information we have on the slides and there is no information on the process Smith used.  I know that there is the Albumen process, and others that used silver bromo-chloride or chloro-bromide silver gelatine emulsions.

Does anyone know what effect scanning them could have?  Also, is there any tell-tell signs we can look for that would give us a hint to what process he used?

Any help you give is greatly appreciated.
