Glass beads can be made into many different things. Beads can be used for necklaces, lampshades, pretty much anything someone could want, anything one could imagine.
Italian glass blowing techniques such as latticinio and zanfirico are adapted here to make beads. Furnace glass uses large decorated canes built up out of smaller canes, encased in clear glass and then extruded to form the beads with linear and twisting stripe patterns. No air is blown into the glass. These beads require a large scale glass furnace and annealing (glass) kiln for manufacture.
The most sustainable beads are pearl beads. They are much stronger and last much longer than glass beads. This is one of the reasons they cost more than glass beads.

One way to test for glass beads is to check their transparency and surface texture. Glass beads are usually transparent and have a smooth surface. You can also perform a hardness test and a specific gravity test to confirm if the beads are made of glass.
YES! Because when you heat the mixture of water and glass beads up at boiling temperature, the water will evaporate and leave the glass beads behind. =-)
If you tap your glass bead on glass it will make a "sharp" sound. If you tap your bead on glass and it makes a "dull" sound, it is most likely not made of glass.
Crystal beads are made from leaded glass, giving them a higher refractive index and more sparkle than regular glass beads. Glass beads are made from silica, soda, and lime, and are generally less expensive than crystal beads. Crystal beads are often used for high-end jewelry designs due to their superior quality and appearance.
