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.


Introduction and definition of redox:

– Batch redox number

– Relations with oxygen partial pressure and temperature

– Optical measurements on the glass

Glass color: transition elements, amber chromophore, reduced green, decoloration

Radiative heat transfer

Sulfur solubility in the melt

Fining principle and mechanisms

Mechanisms and root causes of foaming

Air-fuel versus oxy-fuel furnaces

Cullet and redox control

Seeds and bubbles : identifying the origin

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.
Oscar Verheijen
Oscar Verheijen obtained his PhD from Eindhoven Technical University before joining TNO as a R&D project manager and business development manager of sustainable technologies. He is now R&D and training team leader at CelSian, Board member of the GlassTrend, member of the steering committee of the Dutch Glass Industry (NCNG) and represents the NCNG at European level.
Penny Marson
Penny Marson studied Glass Science and Technology at Sheffield University. She worked in development and process improvement for TV and lighting glass applications at Philips. She joined CelSian in 2012 concentrating on glass melting projects in the lab. As a consultant, researcher and trainer, she loves the challenge to apply experimental work to assist manufacturers in improving their performance while decreasing their environmental footprint.
