Technique Aventurina
The aventurine is a glassmaking technique from Murano developed on the island of Murano in the 17th century. It was first mentioned in a document dating back to 1614 as 'a kind of stone with golden stars inside', at which point it was already mesmerizing people with its unusual and attractive appearance. The technique gets its name from the fact that its discovery happened by chance due to a fortunate coincidence, when it is said that a glass artisan accidentally dropped some metal shavings into the glass mixture. Italians say it happened 'all'avventura', which in Italian means 'by chance'.
The first documented recipe for the technique dates back to 1644, when the Murano master glassmaker Giovanni Darduin described how to create aventurine glass. The recipe involves adding various metallic oxides such as copper and iron to the hot glass mixture, which will cause small particles of the metals to crystallize as the glass mixture cools.
Complicating the process, for such crystallization to occur, the furnace had to be completely turned off, and the metallic particles would slowly separate from the glass base over a few days during the natural cooling of the glass. This was a very difficult process from a logistical perspective, as every time a glass furnace was turned off, it caused work to stop, and reigniting it was quite a large process, as it took time to heat it fully to the desired temperature.
As the industrial revolution reached Murano in the 19th century, the process had a remake. Large volumes of fine aventurine paste were produced that were then skillfully stretched into glass rods, which were then remelted for jewelry making under a small flame, or for glass blowing. This aventurine paste received worldwide acclaim and revived the fame of the Murano glass workshops due to its use in Salviati mosaics and in other pieces of rare magnificence, such as vases, glasses, cups, and bowls produced in the Salviati workshop.
Technique Gold Leaf Inclusion (Inclusione di Foglia d'Oro)
Before casing the glass layers, the molten gather is rolled over a sheet of 24-karat gold leaf (foglia d'oro), which shatters into fine metallic flecks that remain suspended within the glass.
Technique Hand-modeled.
Without the use of rigid molds, the master glassmaker manipulates the thick, incandescent glass mass using pincers (pincette) and hot stretching/bending movements, creating dynamic organic lobes, folds, and waves.
Attributed to Barovier Toso
The company is one of the oldest family businesses in the world, founded in 1295 as Barovier. "The name Barovier derives from the term berroviere (highwayman/policman, which indicates the armigero (person entitled to bear arms) guarding the captain of the people. It is probable that some Barovier, originally from Treviso, settled in Murano around 1291, when a law of the Republic imposed the concentration on the island of all glass furnaces." Jacobello was the first member of the Barovier family to work glass at this time. It is thought that the company originated in Treviso[citation needed]. The Toso family had been established in Murano since around 1350. In the 1400s Angelo Barovier created glass objects which are currently preserved in various museums. Angelo is recognized as significant for uniting the knowledge which had been developed and handed down by family Barovier. He was not only considered and artist but a scientist.
The company became Ferro Toso Vetrerie Artistiche Riunite S.A in 1936 when Vetreria Artistica Barovier merged with Ferro Toso, specializing in crystalline glass, mother-of-pearl glass, and gold-free cornelian red glass.. In 1942, the company was renamed Barovier & Toso.
In 1919–1920, 30 year old designer Ercole Barovier began a 50-year career as the artistic director of Barovier & Toso.[9] "After studying medicine and working as a radio operator during World War One he joined the family firm in 1920 when he and his brother Nicolo took over the management from their father Benvenuto. From 1927 Ercole was the main designer and from 1934, when Nicolo left the company, (he was) also the sole owner." While Barovier did not have formal training as a glassblower, his artistic designs produced objets d'art that have become the most critically acclaimed in the history of Ercole - Barovier. In 1930 he produced his award-winning “Primavera” series. "The Primavera series ... is distinguished by a milky white 'craquelé' glass with the addition of black or blue pasta vitrea trim ("opaque colored glass whose consistency is made to appear like ceramic") and decoration. There was a very limited production of this series due to the fact that it was a result of a glass mixture obtained accidentally so it could never be replicated." One example of this series, a Primavera Pigeon, was sold at auction for GBP 275,000 (approximately $360,000 USD, not inclusive of the buyer’s premium) on October 16, 2019.
Barovier continued to produce innovative designs of which the “Lenti” vase...
