It is thought that, as early as the year 1204, the immigration of artists from different countries to Italy played a large role in the number of skilled glass blowers. As time went on and glass blowers developed and passed on their knowledge to following generations of artisans, they were able to control the color of the glass with startling precision. Decorative techniques were improved and developed, as well, allowing the glass blowers to manipulate the glass to create the elaborate designs that handmade Venetian glass vases are known for.
Some handmade Venetian glass vases are as colorful as a rainbow, while others are one simple hue. It is the ornate design that typically distinguishes Venetian glass. Vases are crafted in a wide range of designs and shapes from odd-shaped contemporary vases with multicolored calcedonio -- an Italian term for the appearance of agate rock -- jutting out from the surface, to classic, even regal vases with graceful lines and swirling textures.
There are many techniques that Venetian glassblowers employ to create elaborate and varied designs. Sometimes other mediums, such as copper, are introduced into the pliable glass as it is being blown into form. Another method infuses colored threads into the glass. There is yet another technique that causes the glass to appear cracked, although the integrity of the glass is not sacrificed at all. The artisan accomplishes this look by immersing the hot glass into cold water, causing the cracks, but then covering the cracked surface with another, stabilizing layer of glass. There are many more, but considering just these few techniques, it is easy to imagine the limitless possibilities that Venetian glassblowers have at their disposal to create beautiful handmade vases.
Collectors of handmade Venetian glass vases consider their hobby a full-time pursuit, keeping a constant eye out for another find, whether it be in an upscale department or furniture store or a second-hand shop or flea market.
