REDOX, FINING AND GLASS QUALITY – ADVANCED TRAINING
8 - 11 June 2026
14:00 - 17:30 CET
Online
Master redox and fining, the key to consistent quality and performance in glass production.
Redox is a critical factor throughout glass production, affecting melting, fining, foaming, seed development, and color. This course will equip you with the skills to quickly identify and resolve redox-related issues, ensuring consistent glass quality, clarity, and color. Learn to monitor and control the redox state at every stage, from batch to finished product.
You should attend if you are interested in:
- Defining and understanding 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
- Identifying the origin of seeds and bubbles
What you take away:
- Know how to optimize your batch recipe and monitor your raw materials 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
Level of seniority
This training is meant for junior professionals to skilled professionals seeking to deepen their knowledge and understand the topic in detail.
Trainers
Corinne Claireaux
Corinne Claireaux studied glass and materials chemistry in Rennes and obtained her PhD from the Sorbonne University in Paris in 2014. She worked as an internal trainer and R&D project leader for Saint-Gobain, improving or developing new glass formulations for different businesses and products (float, glass wool, glass-ceramics). She joined CelSian as a glass scientist and trainer in 2019. 
Cristian Hernández
Cristian Hernández graduated as a Materials Engineer from the University of Antioquia, Colombia. Then he obtained a Master’s degree in Metallurgical and Materials Science at the University of Sao Paulo, Brazil. He worked for 8 years as a Glass Science engineer at OI for different plants in South America, supporting them in color changes, glass quality issues, furnace and batch house ramp-ups, raw materials standardization and implementation of new ones. He joined Celsian as a Project leader acting as a supporter and technical advisor.
