DIY Collodion: A Comprehensive Guide to Homemade Collodion

Ingredients

  • 125 ml of Ether
  • 125 ml of Ethanol
  • 2.5 grams of Cotton (purified)
  • 6 grams of Potassium Iodide
  • 2.5 grams of Iodine crystals
  • 1.5 grams of Cadmium Bromide
  • Distilled Water (as needed)

Steps and instructions

  1. Put on your safety equipment which should include gloves, goggles, and a lab coat.
  2. In a well-ventilated area, dissolve the Cotton in a mixture of Ether and Ethanol. This should be done in a glass container.
  3. Allow the mixture to stand until the Cotton is completely dissolved.
  4. Separately dissolve Potassium Iodide and Iodine crystals in a small amount of distilled water.
  5. Add this to the Cotton, Ether, and Ethanol solution and shake well.
  6. Dissolve the Cadmium Bromide in distilled water and add this to the main solution.
  7. Allow the solution to stand for a few days until the precipitate settles to the bottom.
  8. Finally, decant the solution into a brown glass bottle, avoiding the precipitate at the bottom. The Collodion is ready to use.

Origin stories

Collodion, interestingly enough, is not a food but rather a solution often used in the medical and photographic fields. Its origins can be traced back to the 19th century when it was first used as a surgical dressing. Due to its ability to create a clear film that's both protective and adhesive, it quickly gained popularity in medicine. However, it was the field of photography that truly catapulted Collodion into fame. In the mid-1800s, a photographer named Frederick Scott Archer discovered that Collodion could be used to prepare glass plates for photography, creating images of superior quality compared to existing methods. This process, known as the Wet Collodion Process, revolutionized photography, and despite the rise of modern photographic techniques, it continues to be used by some photographers who appreciate the unique and beautiful images it produces.
