"Overripening leads to fog and loss of speed and contrast. You must stop this ongoing process by using proper stabilizer.

I bet commercial liquid emulsions are all washed, and probably all bromide based."

I was looking at the MSDS of Liquid Light and noticed that besides the bromide and chloride, there was trace amounts of Cadmium salts.

Are the Cadmium salts used for contrast increase, reduction of fog, and would the Cadmum salts act as a stabilizer?

Just one loud remark: I AM NOT ADVOCATING USING CADMIUM SALTS IN SMALL LAB EMULSION PRODUCTION. They are very toxic and bad for the envirnment.
