Love this! I don't think you've contaminated your watercolour malachite. I've seen this happen with other malachite watercolours, like Roman Szmal's too. It's a really interesting reaction! We probably need a trained chemist to help here. I know Katie from Katie's Honey Hues is a chemist...I wonder if she has any idea.

I'm glad to have found your video because none of the malachite pigments I have used are fine enough to make decent oil paint, but you have even used it in rock form and have somehow ground it down into suitable pigment. I have a mortar and pestle for grinding the pigment to a finer level, but the problem is that the pigment stays in a range from very fine to very coarse because of the way the pestle works - it can't make 30g of pigment evenly ground into a small range of particles. I get very gritty oil paint, which by its nature of containing a lot of large particle size pigment grains makes a very matte, very absorbent paint. Do you have any tips how to make better quality malachite oil paint? Thank you - Jason

You need to do the final grind of the pigment with a glass muller and a frosted glass plate (I use a 1/4 inch thick piece of glass and 'frost' the surface with a 400f silicon carbide grit) if you do Instagram, about 7 posts back I have a short video about preparing a glass plate for paint making @kjodigear

Jodi, of course I'm mulling all of my pigments to make oil paint, not just mixing them with oil. I was saying that my malachite pigment as purchased is not very finely ground, so the resulting paint is gritty, thus my attempt to make the pigment finer in the mortar before trying to make more malachite oil paint. I would recommend for your mulling plate not using 400 grade abrasive, but rather about 100-150. Trying to mull with such a smooth plate makes for very tough and tedious work. I find that I need to roughen up the plate after about three small tubes have been produced in order to make mulling progress normally and not take 'forever'.

Hello, I really liked your video and explanation. Did your tests with lindseed oil or poppy oil and malachite significantly shifted in colour after one year? I would like to try this too, but I heard the malachite pigment doesn't go very well with oils, so I'm a bit afraid to waste it. Thank you :)

Yes, the color has definitely changed. It is now a dark green, and I imagine it will continue to change, so I would not waste your pigment in an oil paint! I will do an updated video to show the changes, and will also post some photos on Instagram. @kjodigear

@@KJodiGear Do you think that's just the colour shifting of the oil itself or is the pigment reacting with it maybe? Lindseed oil has some natural yellowing over time, did you have the impression that the tests with malachite darkened more compared to other pigments?

@@vittoriobeghelli3561 definitely not the linseed oil, the other color swatches I made at the same time have not changed. It's the malachite. My malachite sample is likely not pure, so it may be changing faster than a better sample would.

@@KJodiGear Ah yes it's the malachite, maybe the acidity of the oil is the problem. I've seen on Kremer Pigmente that they developed a malachite pigment powder in which every grain is "wrapped" in a film of proteins, they say it prevents the darkening, but I wonder how long the protein could resist to degradation. Have a good day!

I just attended a workshop on making paint pigment from malachite stone.... we ended up with a superfine pigment. the procedure involved many washes in clean water with more crushing and 'mulling' in between. the pigment after the last wash and rub down with the muller was so fine and light as talcum powder.... we added a binder to the final pigment in order to fix the colour and texture.

That's great! Did it make a nice color?
