i have been playing with pigments from the chinese art supply shop. this was labeled azurite. they have changed their packaging now to little zip-lock bags in little boxes but they had one packet left that was the 'old packaging'. they apologised!
they also had some Gamboge shoved in a bottom drawer - yellow resin from a tree that gets collected in the hollow of a bamboo cane. once it congeals and dries they break open the bamboo and sell the gamboge in that stick shape; mustard coloured and shiny.
