I’m thinking about how to develop from the sketches I’ve done on a couple of field trips with colleagues in the FIRE Lab team and, as the research project is about ecosystems and environment, I thought I’d try as much as possible to use natural earths, plants and minerals in my artworks, so I’m putting together a geographic palette. I’ve made a pretty good start already, with graphite, lapis lazuli, ochre, charcoal, Bideford Black, some red sandstone and my own home-made walnut ink.
Over the next few days I’ll be researching and writing about them so watch this space …. 🙂

I’ll be interested to read more in your upcoming posts.
Thanks Sharon. I’ll have to get grinding with my pestle and mortar
This is definitely a ‘thing’. Several artists I know are working with natural pigments in their art. In textiles ‘natural’ dyeing has been the go for quite some time.
I’ve bought some seeds to grow my own on my allotment too
