Dear All,
I have been reading 'Archaeology: Theories, Methods and Practice' (Renfrew
/Bahn). The box on page 325 shows crystal structures under a light
microscope. The text mentions polishing the metal then etching it with a
chemical. Unfortunately, it does not state which chemicals are used. Can
anyone tell me which chemicals are required? I would also be grateful for
some tips on how to do the etching.
Many thanks.
Ian Medhurst
