Yellow ochre, FeO(OH)·nH 2O, is a hydrated iron hydroxide (limonite) also called gold ochre.
From wikipedia: In Ancient Egypt, yellow was associated with gold, which was considered to be eternal and indestructible. The skin and bones of the gods were believed to be made of gold. The Egyptians used yellow ochre extensively in tomb painting, though occasionally they used orpiment, which made a brilliant colour, but was highly toxic, since it was made with arsenic. In tomb paintings, men were always shown with brown faces, women with yellow ochre or gold faces.

Because it matters.” Which seems like such an odd disjointed slogan. I wonder how long overpaid advertising people took to come up with that one… “you do what you can”. I would actually be curious to know how they came up with that slogan. What the thought process (or multiple thought fragmented processes) was. Anyway it should be a good campaign nontheless and I looked at what people/companies were doing and found this quiz by UCL which is along the similar sort of lines to what I was thinking about including in my performance. What I like about this one is the information provided in the ‘correct answer’.
I also loved this tweet by @OrkneyLibrary :
#RecycleWeek so we’re taking back all the books that people have read, putting them onto shelves for people to look through, then giving them out again to all the people who haven’t read them yet. Seems to be working well. ;) #Libraries“
