I have been working with natural pigments again recently, all the more encouraged by being able to buy an all natural acrylic medium to bind the pigments ready for use.
The pigment below was made by gathering a little of the rubble used in our un-made road to fill the potholes. I was interested in how it crushed easily as the cars ran over it. I must discover what mineral it actually is!
After crushing it in a pestle and mortar and putting through a very fine sieve I was able to combine it with the medium and produce a very usable colour.
Here are two pieces of work I’ve made using found and ground natural pigments.
Ochres and oxides, lichen and the pigment above.
