Soda Lime Glass: This is the most popular glass sphere used for grinding media. Larger beads are molded. Some brands are produced from virgin glass while others are produced from recycled glass. Air inclusions also vary which can determine the life span of the bead as it determines the strength of the bead. This is an excellent bead for low viscosity material or low heat processes. Chinese glass contains small levels of lead and arsenic. They should not be used.  Density = 2.5 gm/cc.
