Note 18 — Chapter II · ON FILIGREE WORK.

Fine granules of gold are made by cutting gold wire into short lengths, mixing the cut pieces with charcoal, placing the mixture in a crucible and then heating the whole up to the melting point of the metal. Afterwards the charcoal is washed away, and the gold granules (which have been fused into a round form) sorted according to size by sifting.
