[3] [4] Inside the nodule, flint is usually dark grey or black, green, white, or brown in colour, and has a glassy or waxy appearance. A thin, oxidised layer on the outside of the nodules is usually different in colour, typically white and rough in ...

Some hoes were up to 60 centimetres (24 in) in length. [4] The other main use for the chert was large ceremonial bifaces, spatulate celts and stone ...
