I am investigating the use of verdigris on paper. Ancient manuscripts used verdigris for colouring illuminations. These papers are stained with tea first, and then with verdigris. I know that verdigris will continue to degrade the paper (as with rust). We will see. I have coated these with wax which may inhibit degradation.
My other investigation this week was the effect of coloured wax on paint colour cards. Lots of potential there for combinations of colour. The cards are from Reverse Garbage in Marrickville.

thanks Anthea, I’ll bear that in mind!
If you do, please make sure to wear gloves and wash your hands well after use. I understand it can be pretty bad for you. There is information on Mr Google about how to grow it and collect it.
very interesting to see the verdigris stained paper Anthea. I didn’t realise it could be used that way. I recently painted at a site where there is lots of verdigris (from copper mines). Next time I may collect some to try out. 🙂
