Plate Drying Rack

Description
The wet collodion process largely replaced the daguerreotype process by 1861. A viscous solution produced by dissolving guncotton in ether and alcohol, collodion could be poured onto a glass plate, which was then immersed in silver nitrate to make it light sensitive and inserted into a camera with a cap over the lens to prevent exposure. The photograph had to be taken while the collodion was still wet. The image on the glass plate was a negative, which the photographer could keep or discard by scraping off the collodion. This plate drying rack was used during the wet collodion process.
