Float glass production – The critical role of industrial gases


Although glassmaking dates back to ancient times, in many ways it reflects the same basic processes in today’s industry. In the 21st century however, mass production of float glass to comply with modern building standards and changing legislation has become an art that the ancients could not have imagined.

Playing key roles in this high-tech production of float glass  are nitrogen (N2) and hydrogen (H2), along with an array of specialty gases with high levels of purity and extremely  precise accuracies corresponding exactly to the application.

Within these pure specialty grades, purity can reach up to 99.99999% (7.0), guaranteeing fewer and lower levels of the impurities that cause problems in such an advanced production process, as well as in the associated analytical instrumentation and emissions monitoring.
