to Florence in 1611, publishing L'Arte Vetraria the following year. In 1612, Neri published a seven volume treatise, L' Arte Vetraria, that was a significant step toward systematizing the preparation of glass. The title of the book translates to English as The Art of Glass. The first volume describes the materials, mixing, and melting of the ingredients to produce crystals and colorless glass. Subsequent volumes describe colored glasses, leaded glass, artificial gemstones, enamels, and glass paints. The treatise includes many glass formulations that were devised by Neri by improving on formulations that he became aware of through his work in the Medici court, through his interactions with Ximenez, and likely other sources. The contents of L'Arte Vetraria volume-by-volume are: Basic glass colors and preparation Chalcedony glass Advanced colors Lead glass and colors Artificial gemstones Vitreous enamel Paints and transparent red glass L'Arte Vetraria went through three editions up until 1817. By 1752, it had been translated into Dutch, French, and English. While Neri's contemporary Galileo Galilei made note of L'Arte Vetraria, more widespread recognition of the treatise came later. In 1662, British physician and scientist Christopher Merret published an English translation of L'Arte Vetraria, which included extensive annotations by Merret. Subsequent translations were usually based on Merret's version of Neri's treatise. By 1900, there were an estimated two dozen translations based on Merret's version or on Neri's original version. The L'Arte Vetraria was a standard reference book among glassmakers up until approximately 1900 and served to much enhance the ability of glassmakers to improve upon prior glassmaking processes.
