In 1871 Grt grt Grandad was an 'indigo bleu grinder' and in 1881 he was a 'colour grinder'. Any idea what he did, and why?

Hi Phyl,

A colour grinder is a machine consisting of 3 rollers which are in contact with each other and they are used for reducing the particle size of colour pigments especially in the paint industry. The reduction of particle size can and does result in different shades of colour. Hope this helps.
