schema:abstract "104 - Purple EnamelFor example, start with 6 lbs of enamel base material, as described above [chapter 93]. With this, thoroughly mix the previously described powder, that is to say 3 oz of prepared Piedmont manganese, and 6 oz of thrice cooked copper made with flakes of the kettle-smiths, as was shown [chapter 28].Unite these powders, and mix them well with the above said base material, which goes into the furnace, in a crucible glazed as usual. Leave it to clarify well, then throw it into water and return it to the same crucible. Leave it to cook and to clarify. See if the colour is to your discretion. You can concentrate, or dilute the colour, as required. Remove it as usual, form it into cakes for use by the goldsmiths. It will be a beautiful enamel." ;
