BLUE COLLODION Meaning and
Definition
-
Blue collodion is a type of photographic emulsion that was commonly used in the early days of photography. It is a mixture of a solvent, such as ether, with gun cotton, which is a highly flammable and explosive material made from cellulose. This mixture is then combined with various sensitizing agents, including salts of iron, to create a light-sensitive substance.
The term "blue collodion" refers to the characteristic blue color that this emulsion turns after exposure to light. This effect is due to the chemical reaction that occurs when the iron salts in the emulsion are oxidized by light. This oxidation causes a change in the dyes that are formed during development, resulting in a blue tone in the final image.
Blue collodion was widely used in the late 19th and early 20th centuries as a popular method for creating cyanotype prints, which are blue-toned images. These prints were often used in scientific and architectural documentation, as well as in artistic and creative photography.
Although blue collodion is no longer commonly used in contemporary photography, it holds historical and cultural significance as one of the early innovations in the development of photographic processes. Its distinctive blue tone remains a recognizable characteristic of the cyanotype technique, and it serves as a reminder of the early days of photography and the evolution of photographic technology.

Etymology of BLUE COLLODION
The term "blue collar" comes from the clothing traditionally worn by working-class laborers, particularly industrial workers. The color blue was often associated with manual labor jobs, such as factory or construction work. The term "collodion" does not have a direct connection to "blue collar". Collodion is a substance used in early photography, a syrupy solution primarily composed of nitrocellulose and ether. It was commonly used in the 19th century as a binding agent for photographic emulsions. The word "collodion" itself has its roots in the Greek word "kolla", meaning glue, and the suffix "-ode", meaning resembling.
It's important to note that "blue collar" and "collodion" do not normally appear together as a single term. It seems to be a combination created for this specific context or purpose and might not have a defined etymology.
