Conceptual images of a silver bath tank for collodion wet plates. After iodized collodion is poured on a plate it is sensitized by dipping into a silver bath. The plate will then get light sensitive. The silver bath tank will need to be light-tight, OR made of transparent red material (if one wishes to work with lights on while the plate is being sensitized).

Our plan is to purchase pieces of red Plexiglass (8 mm thick) from a local supplier, then glue them together. This will be a simple tank (with a lid) for plates up to 8×10″ size.

Looks like we little by little are getting the stuff needed for our first collodion pour!
