Glass Beads
	Glass beads are perfectly spherical in shape with a smooth, shiny surface ; they are also extremely hard and totally non flammable. Their chemical inertness (insolubility in water or oil) guarantees that neither thecomponents to be treated nor the environment of the work station are contaminated.
