It is specially designed to measure the color of varnishes, thinners and other transparent liquids.
A certain amount of ferric chloride hydrochloric acid solution, potassium dichromate sulfuric acid solution and cobalt chlorite hydrochloric acid solution are taken. The above three solutions are mixed in a certain proportion to obtain 18 different colors and densities. They were then sealed in separate test tubes.
The solutions were evaluated visually against a series of standard color scale solutions of anvils labeled with color scale numbers. The results are shown in 1-18.
