CLOSED COLLODION Meaning and Definition

1. Closed collodion refers to a process of coating a glass or metal plate with a light-sensitive solution known as collodion, which is a syrupy liquid mixture composed of gun cotton (nitrocellulose) dissolved in alcohol and ether. This process was primarily used for creating negatives in photography during the mid-nineteenth century.

   In the closed collodion process, the plate is first thoroughly cleaned and then coated with collodion, typically tinted with potassium iodide and bromide salts. The plate is then plunged into a silver nitrate solution, which forms light-sensitive silver iodide and silver bromide salts upon reaction with the potassium salts in the collodion layer. The plate must be kept in total darkness throughout this process.

   Once the plate is removed from the silver nitrate bath and loaded into the camera, it must be exposed and developed while still wet. This process requires swift action to prevent the collodion from drying out, as it would render the plate unusable. After exposure, the plate is quickly developed using a solution of iron salts, which produces a negative image with a high level of detail.

   Due to the elaborate process and the need to work with wet plates, closed collodion photography required meticulous preparation and skilled photographers. The resulting negatives created using this technique were widely acclaimed for their sharpness and tonal range, making it a highly popular method during the mid-1800s.

Etymology of CLOSED COLLODION

The term "closed collodion" is not a common term in English. However, "collodion" does have an established etymology.

The word "collodion" comes from the combination of two words: "collodium" and "-ion".

1. "Collodium": This term was coined in the early 19th century by a British chemist named George Fownes. He derived it from the Greek words "kolla" meaning "glue" and "odeion" meaning "theatre". It was initially used to describe a sticky substance used for applying stage makeup.

2. "-ion": The suffix "-ion" is a common noun-forming suffix in English, derived from the Latin suffix "-io(n)". It is used to create nouns that often denote an action, condition, result, or state.
