"The invetriatura now having been thus applied and the pieces allowed to dry are now ready to receive the painting. This is executed with coarser and finer brushes or penelli, made of goats' and asses' hair, and the finest of the whiskers of rats or mice; the ordinary wares being held in the left hand or on the left knee and the finer in wooden cases, lined with tow, to prevent rubbing. A different brush must be used for each colour. The painters generally sit round a circular table suspended from the ceiling so that it may turn round, and upon this the different pigments are placed."
