Note 785 — ARTIFICIAL PEARLS.
William Johnston translation
A complete account of the art of making glass pearls is contained in a book, which I have however not seen, entitled, L’Art d’imiter les perles fines, par M. Varenne de Beost. An extract from it may be found in Dictionnaire des Arts et Métiers, par M. Joubert, iii. p. 370. See also the articles perle and able in the Encyclopédie, i. p. 29; xii. p. 382.
