Making Cobalt Violet Pigment

[@caffeinette]

Excess ammonia could be coordinating to some of your cobalt ions - maybe that is what's resulting in that difference in color?

Mmmm... Forbidden parma violets!!!

I am making pigments and have seen this done with cobalt chloride, monosodium phosphate, sodium hydroxide and ammonia. Alchemical Art channel

Thanks dude! It's growing slowly but surely. Plan to Redo most of my pigment videos soon so stay tuned!

[@chemistryofquestionablequa6252]

This looks really cool, might make some.

[@integral_chemistry]

Thank you! I actually want to Remake this video because I found that the pigment as I made it here seems indefinitely stable in oil, but lost color in water suspension after about 6 months. I think the heating phase needs to just be longer to allow the pigment to fully stabilize

@@integral_chemistry thanks! If I make it I’ll remember to do that.

Amazing!

[@spiderdude2099]

Cobalt compounds frequently shift between a pink and blue form due to things like temperature, water of crystallization, and other factors, so I’m not at all surprised that this happened
