Yesterday I boiled up some gum tree bark, hoping I might get some orangey colour - thinking about the terrible fires in Australia.
The pure colour is a sort of orangey/golden colour and when I added aluminium and copper it went a wonderful dark olive green.
I have some wool tops sitting in the pure colour to see what will happen. I don't want to boil them and shock them so they felt and matt before I use them. I will check them tomorrow.
