Notes:
"3rd draft, D.C. Watts"--Cover.
Translation of the transcription of a Venetian batch book ca. 1560.
For 2010 pre-publication edition, see bib 119595. See bib 126786 for 2011 published edition.
"The original text, written in the form of an instruction manual for an apprentice, provides detailed instructions on the purification of the chemical ingredients used, the exact amounts required for a particular recipe, the type of pot to use and state of the furnace. It covers plain glass and cristallo, coloured glasses, enamels and the manufacture of mosaics, particularly those involving gold and silver foil inclusions. Comparison with other recipe books explodes the myths that Venetian cristallo and the base glass used for colours was always a pure soda glass and that cristallo was invented by Angelo Barovier"--P. [4] of cover.
Includes bibliographical references (p. 89-92).
Includes handwritten corrections.
