Making a Round Venetian Bead

The round bead is the first one you learn how to make. And most of our other shapes take off from the humble round bead. So it is the building block and our most popular bead shape. We buy and sell many thousands of round Gold Foil beads each year.

Murano Glass Torch for Making Beads – the Cannello

First you’ll need a torch, the kind we use in Murano is known as a cannello, it burns without oxygen and at a lower temperature (about 200 degrees) which allows our bead makers to add millefiori, exterior gold foil and to work the bead for a longer time than can be done in American torches. On the other hand, the American torches allow the bead maker to work in a pinpoint flame, which is useful in small decorations but require oxygen.

Effetre Glass Canes – Let’s Make Some Beads

It All Begins With the Canes

It all begins with the selection of the glass canes and there plenty from which to choose. We use Effetre, known generally in the industry as Moretti. It is a soft glass with a COE of 104, Soda Ash Glass which contains no lead and is worked at temperatures of about 945 C which is about 1733 F. Our bead makers work with larger diameter canes and we buy the canes 20 kilo at the time. They know to the gram how much glass it takes to make a bead!  So, if we are working on a large order, we want all the beads to be from the same glass batch in the factory in Murano. Because, like carpet and fabric, each batch of glass is slightly different.

Decorations on a Round

 

Tools of Bronze for Round Venetian Bead

Bead Makers – Can you Rub Your Tummy & Pat Your Head?
While we say that the round is the easiest shape to make, it’s still difficult work sitting in front of the heat, attempting to roll the mandrel in one hand while making sure that the cane is in the heat and wrapping around your mandrel. Well it takes some practice, rather like rubbing your tummy and patting your head at the same time.

Shaping the Round

 After you master the round bead you can advance to making many other shapes, it is about learning how much glass you need on the mandrel to make squares, bicones, hearts which we make with tools especially made for forming the shapes.

All these shapes begin as a round

 The bead must be thoroughly heated so the temperature is the same throughout the bead which is part of learning how to recognize this when the entire bead is red hot. In Murano, the maestro speak about “knowing” the glass. It is a feel and knowing the exact shade of red you need to be sure the bead is thoroughly heated. Once you are happy with the shape and any decoration, it still must be flash annealed (again to be sure the temperature is consistent).

Rounds Ready to Cool – Vermiculite

Many of our beads are annealed in an electric “furnace” which lets the beads stay at a consistent temperature and then slowly bring the temperature down to prevent shock and breaking. Some of the smaller beads are annealed in vermiculite as in the picture above (the traditional method, though in early days it was just sand from the lagoon).
And they are made one at the time, and as we like to say “No two ever exactly alike!” the beauty of lampwork.
