- Description
- Empty cardboard box of Kokak Solio Toning and Fixing Powder cartridges with manufacturer and product details printed throughout the white box in red and black. Toning powders were chemical compounds designed to react with the emulsion layers of positive photographs that altered the tone (or colour) of the image, usually turning a standard black-and-white image into warmer shades of red, brown, and/or purple - sepia is a very common tone. Additionally, toning powders could be combined with a fixing agent that stabilized the emulsion layer to prevent it breaking down or fading, flaking off, or otherwise ruining the image as it set.
