working with flame

How does one make a lampworked glass bead?

Take a steel rod of 2 – 3 mm diameter, coated with a clay release agent, and heat up this rod in the flame.  With the other hand, select a glass rod of the color needed, and introduce this slowly to the flame as well.  The end of the glass rod will begin to melt, and form a blob, or “gather.”  Drip this onto the rod, and wrap it around.  Click on the photo for a larger view.

I usually marver the bead now, by rolling it on a flat surface until it takes a cylinder shape, and use this as my canvas to paint with more colors.  I keep adding layers of color, and often finish the bead with some clear glass encasing.

The bead can be rather lumpy at this point, like a raspberry.   I heat it up further until it is entirely molten, and takes on a smooth rounded shape.  You must continually rotate the rod to keep the bead centered.  If you wish the bead to be textured you skip this rounding.  The bead can also be shaped by rolling it on a flat surface, or pressing it into a mold.

Then let it cool down until the normal colors return to the glass, and put it away in a kiln or warming thermal blanket to rest for several hours.  The next day it can be taken off the rod:   after a soak the clay rinses away and it twists free, the bead is complete and the rod can be re-coated with clay for the next dance.

The flame is a Minor lampworking torch with a mixture of propane and oxygen fuel.  Proper ventilation and didymium safety glasses are essential.  Wikipedia has several good entries relating to beadmaking and glass art.

Making beads

People are sometimes puzzled when they see my jewelry.

You made the necklace, and the beads?  The bead stringing they can understand, but they are sometimes shocked to hear that I made the beads themselves and ask how.

It all starts with glass rods and a torch.  Here you see my work area with the many colors of glass rods arrayed on a hotplate.  The red knob at lower left is part of the torch.  At lower right you see the didymium safety glasses.  Click on the photo to see a larger view.

Lampwork is the term used to describe working with molten glass using a small ‘lamp’ or torch.  The beads are made by heating up the glass rods until liquid, and wrapping it around a steel rod coated with a release agent.  After the bead is complete, the rod is removed and that leaves a hole in the bead.
