REDOX, FINING AND GLASS QUALITY (ADVANCED TRAINING)
Redox is a key element of glass production that has consequences all along the production chain. This course will develop your ability to recognize and resolve redox-related problems more quickly. The redox equilibrium influences each step of the production process. Explore how it affects melting and fining, foaming, seed development, and color changes. Discover how to monitor and influence the redox state in the batch, melt, and finished glass.
Contents
• Introduction and definition of redox:
– Batch redox number
– Relations with oxygen partial pressure and temperature
– Optical measurements on the glass
• Glass color: amber chromophore, reduced green, decoloration
• Radiative heat transfer
• Sulfur solubility in the melt
• Fining principle and mechanisms
• Mechanisms and root causes of foaming
• Cullet and redox control
• Seeds and bubbles: identifying the origin
After the course you will
• Be able to optimize your batch recipe and monitor your raw materials in order to obtain a satisfactory redox
• Know the available technology to track the redox state of the melt in the furnace
• Identify the ideal fining conditions for the manufacture of glass
• Quickly troubleshoot process or quality concerns (e.g. foaming, energy consumption, color, seeds, bubbles) and detect redox issues
