REDOX, FINING AND GLASS QUALITY (ADVANCED TRAINING) SPRING
14-17:30 CET, 8-11:30 EST
Redox is a key element of glass production that has consequences all along the production chain. The course starts with a definition of the redox state in the batch, melt, and final glass. Then, it describes how redox influences the melting and fining process, foaming behavior, seeds formation, and color variations. You will be able to diagnose better redox-related issues and find solutions faster.
