The Foundry at Domus Orsoni

+ Read Article

While in Italy checking out the latest in tiles at Cersaie in Bologna, we took a day to train over to Venice and roam the waterways and were given the opportunity to visit the only foundry in the city: Domus Orsoni. Here's what we saw at the 122-year-old establishment and hub of mosaic magic.

  The foundry at Domus Orsoni was opened in 1888 by Angelo Orsoni, and his great-grandson, Lucio, has carried on the family tradition and is now the honorary president. Here, he stands in front of a 24k gold leaf mosaic, and explains how his family foundry has made glass for the Sagrada Familia in Barcelona, and the Roman Pool at Hearst Castle in San Simeon.

  Smalti is a specialized glass used in many mosaics, made from a mixture of sand, soda, stabilizing compounds and mineral oxides, which add color. Here is a multi-hued pile of crucibles, or pots, where the ingredients are melted together to produce “pizzas”, or slabs.

  There are 2800 colors in the Orsoni color library—100 of them are standard, and the rest made exclusively for clients and specific projects—and the smalti lines the shelves and fills the bags from floor to ceiling.

  When these large, "pizza" slabs are cut into smaller smalti tesserae, it's actually the interior edge—not the large surface—that becomes the exposed element. Generally, artists and designers to receive smalti in its smaller form. For large decorative surfaces, these smalti piastrina—which have a smooth exterior surface—are used.

  Bags and bags of brightly-colored smalti fill up the floor space of the color library. Once they’re in this form, they’re ready to be shipped directly to artists, designers who either use those pieces intact, or in many instances cut them to size with a hammer and hardie.

  After a gold leaf layer is laid on the conveyor, this man drops a dollop of molten glass atop. Together, they are flattened out into a round slab called 'piastre di oro da spelare,' or "plates of gold with edges.'

  A woman scores each fired slab, then taps off the rounded edges with a steel chisel called a martellina. The grooved grid of 16 3/4-inch-squares is then sent to be cut.

  Antonella Gallenda has been working with Lucio since she was 16 years old. She teaches mosaic classes at the foundry (three, five, and ten day courses accredited with IIDA, ASID, and IDEC) and works on commissions using tiles made at Orsoni.

  Opulence: This has it. Above the ground floor gallery and offices, Domus Orsoni is a full-service bed and breakfast. Each of the five bedrooms and bathrooms are decorated in Orsoni mosaics by Italian architects and artists, natch. Here’s a view of the floor to ceiling gold tiles that lined one of the bathrooms.

  In Italia, the horned cows say ‘MU!’ This strange—and strangely enthusiastic—beast was my favorite bit of street art in Venice, caught along one of the many (many many many) canals.
