HOW LITHIUM BENEFITS PRODUCTION GLASSES.

Lithium is a proven material of valuable use in glass technology. Increasing investigations in the area of 0. 05 to 0. 5 per cent Li//2O in glass have shown that minor Li//2O additions can benefit many of the present production glasses. The advantages in using lithium in minor per cent additions to glass are: increase pull, lower melting temperatures, increased durability, increased fining rates, and ease of use requiring only available mix house equipment. Some glasses may receive the possible additional benefits of: a decrease in liquidus temperature, a decreased volatility from the melt, and an increased surface tension.
