GLASS MELTING TECHNOLOGIES – INTRODUCTORY TRAINING
9 - 12 March 2026
14:00 - 18:00 CET
ONLINE
Master the core melting principles that drive quality, efficiency, and furnace longevity.
This course gives you the foundation to make strategic decisions about furnace design, operation, and raw materials. You’ll learn how melting behaves across different furnace types and how to manage energy use, CO₂ emissions, and product quality at once.
Attend if you are interested in:
- Melting Systems
- End-port, cross-fired, oxy-fuel, and electric furnace
- Energy flows and losses in different configurations
- Fining process and its role in glass quality
- Material Interactions
- Glass furnace as a chemical reactor
- Raw materials, carry-over, and recycling
- Condensation, evaporation, and refractory wear Sustainability
- Energy consumption and reduction strategies
- Environmental impact and emission controls
- Introduction to carbon-free melting
What do you take away:
- Know how raw materials affect melting behavior and furnace lifetime
- Understand links between fuel choice, CO₂ emissions, and furnace design
- Identify furnace settings that influence energy use and quality
- Troubleshoot common furnace issues with more confidence
Level of seniority
This training is meant for junior professionals to skilled professionals seeking to deepen their knowledge.
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.
Sjoerd Stelwagen
Sjoerd Stelwagen studied Chemical Engineering at Eindhoven University of Technology. Directly after his study he started as a Technical Specialist at the Furnace department of Ardagh Glass in Dongen, The Netherlands, where he later became Batch and Furnace Manager. He then evolved as EHS manager for the Benelux plants. With more than 16 years of practical glass making experience, he joined Celsian in 2021 to work as a project manager and trainer.
Jeff Watts
Attended Ohio State University, majoring in ceramic engineering. Worked in PPG Industries as a production engineer. At Anchor Hocking, he researched raw materials to improve glass quality and reduce costs. Spent 18 years at O-I, starting as a senior global furnace operations engineer. He was promoted to global furnace operations leader. In this role, he led an international team and oversaw the development and implementation of a global standard for furnace operations. In 2024, he joined CelSian as operations project leader.
