LADDER Oval Bowl by TIOZZO SERGIO
Black and white, opposites that attract and melt into each other: this is the essence captured by this wonderful like of Murano glass products, featuring black glass with central filigree embellishment. The filigree, with its parallel lines that weave through the composition, seems to be holding it together, creating a game of light and shadow with incredible contrast. This series of products is born to amaze and draw attention in any room of your home. Modern taste and essential design make it a refined, unique product for any setting. This series includes three plates in different sizes and a tray, all entirely handmade.
VETRERIA TIOZZO SERGIO
The Company, founded by Sergio Tiozzo, has been handed over to his son Claudio.
Claudio Tiozzo started working in the family workshop from a very young age, where he learned all the secrets of the Murrina technique. According to Murano tradition, he apprenticed for a while in the biggest furnaces of the island: Barovier & Toso, Venini and Aureliano Toso.
Starting in 1989, he has been directing the family furnace. The primary objective of his company is to create fine quality objects using one of the most ancient glass-making processes: the "murrina".
This kind of manufacture requires a very delicate and meticulous process that only expert hands can perform correctly. Beside this traditional production, Claudio Tiozzo is fond of experimenting with glass in its infinite forms: the results of this additional collection are spectacular, one example among all are his chandeliers made of "cotisso" glass.
"MURRINO" GLASS or HOT-WORKED MOSAIC
The hot-worked glass mosaic is based upon glass canes; they are produced in very few furnaces, due to the complexity of its manufacturing.
The master picks up a cylindrical mass of molten glass (the "paston") with the cane-making rod, and joins it to a smaller blob (the "conzaura") attached to a short rod. He then hands over one of the rods to his assistant, then they slowly walk away from each other lengthening the glass rope.
As the glass quickly cools, they carefully set down the hardened cane onto rough wooden boards on the floor. The evenness of the cane depends exclusively on the superior craftsmanship of the master. A special type of cane is called "millefiori"; it is a hollow or solid cane composed of concentric multicoloured layers which, in cross-section, form a typical star- or flower-shaped pattern.
These canes are produced by filling open moulds in succession, creating each pattern by layers of different-coloured glass. The finished cane is used by cutting into small segments and arranged onto a horizontal metallic plate, coated with purified lagoon-marsh mud -- this is the only substance able to isolate melting glass from metal. The arrangement is melted inside an oven and picked up for further processing, usually blowing and shaping with tongs. It is this initial procedure that determines the pattern and size of the object, whether one uses solid canes, geometric plates, filigree or aventurine, and creates an infinite variety of unique products.
Filigree is a type of glass featuring thin, opaque, white "lattimo" glass threads: depending on the position of these filaments, the patterns take on different names. The three classic filigree patterns are: "a retortoli", when the threads are twisted together almost to mimic fabric (also called "zanfirico"); "a reticello", when the filaments are criss-crossed forming a small web, usually with bubble inclusions; and the "mezza filigrana", where the threads are arranged diagonally.
To create a twisted filigree, the master glassmaker sets up thin clear rods with spiralling white or coloured threads running through them, placing the segments of the rods side by side to form a rectangle. This arrangement is then melted in the oven to form a rectangle, which is then rolled into a cylinder and sealed at both ends. At this point the master can blow the artefact and shape the final product.
The half filigree is obtained by the same initial procedure, except the threads within the clear rods run linearly rather than in a spiral. Once the cylinder is ready, the master twists it to impart a diagonal direction to the parallel strands. If two half-filigreed objects are blown one inside the other, with strands running in opposite directions, the effect is that of a fine web, the "reticello". Since the surfaces of the two blown objects are still wavy at the time of bonding, each crossing of the mesh traps a tiny bubble, adding to the decorative effect.
