I was looking around at soap making supplies with a view to make a shave soap when in the colouring sections I stumbled upon Chromium oxide powder.
Would this be the same sort of stuff I would want for my strops or is it likely to be of a different grade? If usable, would it need mixing with anything?
Strange i was looking for a source for it last week and couldn't find one in the UK, and I manage to stumble upon it by accident this week.
