My Bubbles collection was inspired by the fabulous depth of colour and dimension of these beads.  The technique uses a combination of heat and baking soda to create the bubbles and a heavy encasing traps the bubbles just under the surface.

While these beads are annealed for added durability, they are a little more fragile than beads not created using this technique.  Special care should be taken not to drop them or expose them to boiling water.
