Neri traveled to Antwerp in early 1604 to visit his friend Emmanuel Ximenes (Pronounced Se-men-ez), where he stayed for seven years. Ximenes was an international trader (known then as a 'banker') from one of the wealthiest families in Flanders. At the time, Antwerp stood at the center of the bloody Dutch war for independence from Habsburg Spain. The population of the city was a shadow of its former self, after being sacked and burned by Spanish troops a couple of decades earlier in what has become known as "the Spanish Fury." A Dutch blockade of Antwerp's seaports had strangled commerce, but for the ultra-wealthy, life went on.

The most fashionable street in Antwerp was the Meir. This was the address of Ximene's palace, as well as of his brother in law, Baron Simon Rodrigues d'Evora, who happened to be the most prestigious diamond dealer and jeweler in the region; he was known locally as "the little king." Gridolfi and Vincx had one, and later a second retail space for their glassware here. The factory and furnaces were located a few blocks away, near the fortress wall that ringed the city. Records indicate it was in a district called the Hopland, near -- or possibly also in -- a huge structure called the "Blauwe Toren" [Blue Tower] which had at various times functioned as an armory. In this period, a below street level canal led from the basement of the tower directly to the Meir, in later years it was filled in. Just on the other side of the city wall was a mote with access to the network of waterways which connected towns and villages throughout the region; this too was eventually turned into usable real estate when the wall was demolished in the nineteenth century. This situation of the glass production makes perfect sense. They needed to bring in heavy materials, ship delicate product and occupy a space which was not in danger of burning down the city should disaster strike.

What we know of Neri's experiences in glassmaking come mostly from his book. His activities in Florence included making aquamarine colored glass for beadmaking and chalcedony glass with its multicolored swirls. In Pisa, he made emerald green, pimpernel green and celestial blue glass, he experimented with enamels, constructed a frit kiln and made glass using fern plants. From his early glassmaking activity in Florence, Neri seems to build momentum in Pisa. In these two locations he spends at most four years, in Antwerp he spend seven years, and there is no indication that he is slowing down, in fact quite the opposite. There he made artificial gems, a "beautiful aquamarine so nice and marvelous, that you will be astonished." He tinted rock crystal "the colors of balas, ruby, topaz, opal and girasol." He "built a furnace that held twenty glass-pots of various colors" He made ultramarine, the deep blue pigment valued by painters more highly than gold. Finally in 1609, in Antwerp, at Gridolfi's shop he made "the most beautiful chalcedony that I have ever made in my life" and presented two vessels of this glass to the prince of Orange.
