Venetian glass is a type of glass object made in Venice, Italy, primarily on the island of Murano. It is world-renowned for being colorful, elaborate, and skilfully made.

Many of the important characteristics of these objects had been developed by the 13th century. Toward the end of that century, the center of the Venetian glass industry moved to Murano.

Byzantine craftsmen played an important role in the development of Venetian glass, an art form for which the city is well-known. When Constantinople was sacked by the Fourth Crusade in 1204, some fleeing artisans came to Venice. This happened again when the Ottomans took Constantinople in 1453, supplying Venice with still more glassworkers. By the 16th century, Venetian artisans had gained even greater control over the color and transparency of their glass, and had mastered a variety of decorative techniques.

Despite efforts to keep Venetian glassmaking techniques within Venice, they became known elsewhere, and Venetian-style glassware was produced in other Italian cities and other countries of Europe.

Some of historical factory of glass in Murano are today the most important brand of glass in the world: Venini, Barovier & toso, Pauly, Seguso.

The oldest factory of glass are Pauly & C. - Compagnia Venezia Murano (it was founded in 1866)

Millefiori is a glasswork technique which produces distinctive decorative patterns on glassware.

The term millefiori is a combination of the Italian words "mille" (thousand) and "fiori" (flowers). A. Pellatt (in his book "Curiosities of Glass Making") was the first to use the term "millefiori", which appeared in the Oxford Dictionary in 1849. The beads were called mosaic beads before that time. While the use of this technique long precedes the term millefiori, it is now frequently associated with Venetian glassware.

More recently, the millefiori technique has been applied to polymer clays and other materials. Because polymer clay is quite pliable and does not need to be heated and reheated in order to fuse it, it is much easier to produce millefiori patterns than with glass.

Glassblowing is a glassforming technique that involves inflating the molten glass into a bubble, or parison, with the aid of the blowpipe, or blow tube. A person who blows glass is called a glassblower, glassmith, or gaffer.
