Recognizing the importance of cooperative technology planning, the US glass industry organized a Glass Technology Roadmap Workshop, held 24-25 April 1997 in Alexandria, Va. This collaborative workshop brought together 38 experts from the glass industry, universities and the national laboratories to help identify key targets of opportunity, technology barriers and research priorities in the glass industry, covering all sectors, flat glass, container glass, specialty glass and fibreglass. The Glass Technology Roadmap Workshop provided an opportunity to verify and validate the initial findings of the subcommittees and gain additional input and insight by expanding participation to include a broader cross-section of glass producers, research performers and industry experts.
