CHAP. 17.—LEUCOPHORON.
Half a pound of Pontic sinopis, ten pounds of bright sil,[1]
and two pounds of Greek melinum,[2] well mixed and triturated
together for twelve successive days, produce "leucophoron,"[3]
a cement used for applying gold-leaf to wood.
1. See B. xxxiii. cc. 56, 57.
2. A white earth from the Isle of Melos. See Chapter 19.
3. See B. xxxiii. c. 20. "One may readily conceive that this must have
been a ferruginous ochre, or kind of bole, which is still used as a ground,
poliment, assiette."—Beckman, Hist. Inv. Vol. II. p. 294. Bohn's Edition.
