Advanced Chemical Tempering Of Glass

Greater applications than those for the traditional heat process for strengthening glass have led to increased interest in chemical tempering. One company active in the field is Iontech, part of the Finind Group. In this article, the author looks at this glass-strengthening process and at the advanced technology now available. Emphasis is also placed on the possibilities of overcoming the limitations of heat tempering, and on the fact that chemically tempered glass has higher bending and impact resistance.
