I've recently started contributing innovative biomaterial recipes to an open source material library; materiom.org.
I have been aiming to source ingredients that are ethical, sustainable, and certified organic. Some of the notable contributions are natural dyes from fruits and teas, and a guar gum bioplastic.
There is something about the experience of creating a material from scratch, and then utilizing the material in an artwork that is satisfying to me right now... I hope the work inspires!
