In a recent peer workshop, one of my fellow student-teachers proposed making paints out of sustainable materials.
No stranger to making watercolours and ceramic stains out of natural pigments, I was intrigued by how she would turn these into “acrylics”. I took careful pictures of the recipes (she took from the internet): coffee grounds and cocoa powder for brown; frozen blueberries for purple; raspberries and cayenne pepper for red; turmeric powder for yellow.
She then mixed them with some store-bought, acrylic medium. While I don’t see this as very sustainable, the basic idea is sound. We can easily pull pigments from organic materials.
Usually, alcohol is a better material to pull them out and evaporates. It’s also organic. As for making a gummy, acrylic like consistency, there are natural glues (rubber, milkweed, etc…).
For the ceramic pigments, I use minerals mixed into a good clear glaze base. The reason I’m sharing this is that it yielded some nice pictures.
I’m considering doing an in-depth seriess of making colours, but that will have to go to the end of my current To Do list.
