RAW MATERIALS AND MELTING – INTRODUCTORY TRAINING

18 - 21 May 2026
14:00 - 17:30 CET
Online

Unlock improved melting, fewer defects, and lower emissions, starting with your batch.

The batch defines your melt. This course explains how raw material choices impact redox, energy use, foaming, and emissions. You’ll also learn about cullet, segregation, moisture, and how to prepare a stable, optimized mix.

You should attend if you are interested in:

  • Batch Fundamentals
  • Raw material properties and specifications
  • Batch recipe formulation and redox potential
  • Impact of water and fines
  • Melting Behavior
  • Cullet use, segregation, and handling
  • Melting reactions and energy needs
  • Redox, foaming, and emissions

What you take away:

  • Select raw materials that support your melting and quality targets
  • Minimize handling issues like segregation and moisture imbalances
  • Adjust redox and batch composition to improve energy efficiency
  • Evaluate innovations that can reduce emissions or costs

Level of seniority
This course is meant for novice to junior professionals who would like to improve their understanding and apply the knowledge in practical cases.

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.
Katelyn Kirchner
Katelyn Kirchner obtained a Ph.D. in Materials Science and Engineering from the Pennsylvania State University, USA. She holds 2 collegiate-level Teaching Certifications and is a certified online and in-person professor. In addition to her 4 years of experience teaching, Katelyn brings 8 years of experience investigating structure-property-performance relationships in glass. Her expertise centers around glass structure, statistical mechanics of glass forming, and the physics of critical atomic glass behaviors, including glass viscosity, relaxation, crystallization, crack propagation, and heat transfer. Katelyn has worked in industrial and academic research groups in Japan, Germany, and the USA. She now studies glass melting at the manufacturing scale, as a Glass Process Scientist at CelSian.
