He then became a member of the household of Alamanno Bertolini where he met the chemist Sir Emmanuel Ximenes, who introduced Neri to the fundamentals of glassmaking.

[1] Bertolini was a member of the Medici royal family, and his household in Florence was known as Casino di San Marco.

Much of his time in Antwerp was spent with chemist Sir Emmanuel Ximenes from whom Neri learned much of the basic chemistry of glassmaking.

Following the publication of Il Tesoro del Mondo, Neri began his travels to Antwerp and Pisa, during which time he interacted more frequently with Ximenes.

[3]: 32 In 1612, Neri published a seven-volume treatise, L' Arte Vetraria, that was a significant step toward systematizing the preparation of glass.

The first volume describes the materials, mixing, and melting of the ingredients to produce crystals and colorless glass.

[4] While Neri's contemporary Galileo Galilei made note of L'Arte Vetraria, more widespread recognition of the treatise came later.
