Other lead - free and environmentally friendly crystal beads. Different sizes, designs and shapes. Colored crystal beads are always dyed through. Crystal glass is more environmentally friendly than lead crystal, but instead of lead oxide, barium oxide, zinc oxide or potassium oxide is used in its manufacture. This method gives a very high refractive index to the glass instead of lead, which creates a strong spark when light hits the surface of the moving bead.
Crystal glass is a different glass than pressed glass, so crystal glass is also called crystal.
