Cadmium Yellow Attempt #2

Reupload from my Tik-tok
This video also includes an easy hydrogen sulfide generator demo I came up with.
Materials: Cadmium, hydrochloric acid, sodium hydroxide, sulfur/sodium sulfide
Hazards: Cadmium is toxic, carcinogenic, and a reproductive toxin. Strong acids/bases can cause serious burns, and hydrogen sulfide gas is extremely toxic and lethal.
Methods: "The manufacture of mineral and lake pigments, containing directions for the manufacture of all artificial artists' and painters' colours, enamel colours, soot and metallic pigments" 1901

this hue would be usefull for nature colors such as autum leaves or autum underbrush, also could probably mix in some other white insoluable pigment to get a lighter color.

It should also be noted that soluble cadmium salts are very dangerous. They will easily get into your body to do damage and practically never leave.
Many steps here create significant amounts of aerosols and must be done in proper fume hood.

Yeah.. I've been meaning to make a formal broad-spectrum safety video and post it to my front page to address things like that.. I'll probably get around to it soon.

Cad yellow has been around for centuries. How did they make it before modern chemistry techniques ?

[@chemistryreacts]

It can be produced through less spicy precipitation reactions or dug up from the ground in nature.
