I use the lake pigment method to make most of my paints, though it’s a little different for blueberries — I soak them in isopropyl instead of water to make dye.
After that I use an acid/base reaction to precipitate the colour out of solution, let it dry, pulverize the resulting hard cake of pigment, and mix with glycerine, honey, gum arabic solution and clove oil to make watercolour paint I dry in pans.
Yes, my muller is a glass butt plug and my pallette is a microwave platter. I’m industrious, not rich.
Wow, so cool! And very inspiring! I like that you are so creative - with your tools and your sources for pigments.
Thank you. Poverty breeds ingenuity!
I just wanted to dye my own wool instead of having to buy all the colours. It was a slippery slope from there to blueberry paint.
