CHARLES H. DRUMMOND, III, PhD, recently retired from The Ohio State University as Emeritus Professor in the Materials Science and Engineering Department. Drummond has been the Director of the Annual Conference on Glass Problems since 1974 and is a recipient of the Ohio Governor's Emerging Technology Award and the American Ceramic Society's Cramer Award.

Sets forth innovative, viable solutions to challenging problems in glass manufacturing

Since 1934, the annual Conference on Glass Problems has addressed the challenges facing the glass industry with innovative solutions that have led to new and enhanced glass products and processes. Each year, the proceedings from this conference, which has become the largest industrial glass meeting in the United States, have been published for the benefit of glass, ceramics, and materials scientists and engineers around the world.

This volume features the state-of-the-science collection of papers presented at the 72nd Conference on Glass Problems. During the conference, leading international scientists and engineers met for two days to discuss the latest innovations and solutions for glass manufacturing. Moreover, they forecasted and explored future directions of the glass industry. The proceedings are grouped into five sections:

• Glass melting
• Legislation, safety, and emissions
• Refractories
• Recycling and batch wetting
• Process control

References at the end of each paper enable readers to explore individual topics in greater depth.

The 72nd Conference on Glass Problems is essential reading for all scientists and engineers who need to stay abreast of the latest research in the field. All readers will find valuable information that enables the glass industry to continue to innovate with new and improved glass products and processes to meet the needs of both industrial and general consumers.
