Note 35 — PART VI. (continued 2)
Charles Lock Eastlake translation
Borghini, in describing the method of making a gold-size (the same as Cennini's), speaks of boiling the "buccie de' colori" in oil; this only means the skin or pellicle of the colour itself—in fact, he proceeds to say that they dissolve in boiling. Vasari, in describing the same process, uses the expression "colori seccaticci."
