Recently, MCCOGS received a collection of about 100 glass plate negatives. Glass plate negatives are photographic images captured on a piece of glass about the size of a postcard--but a lot heavier! The donor tells us the photographs were taken in and around the Chandlersville-Rix Mills area of the county, and that many, if not all, might be associated with the Mautz and allied families. They probably were taken around 1900-1915.

Silver gelatine dry plate negatives came into wide use in the 1880's, and continued so into the 1920's when they were supplanted by photographic film. However, because of the high quality image produced from photographic glass plates, astronomers continued to use them into the 1990's. A few artists still use the technology, but most companies, like Kodak, have ceased production. Digitization has rendered glass plate negative photo processing all but obsolete.
After cleaning and scanning, each glass plate will be encased in its own archival-quality envelope, and placed on edge in an archival-quality box specifically designed to safely store glass plate negatives. Given the number of glass plates in the collection, this entire process will take some time, but eventually these photos will be available for viewing. We'll keep you posted.
