GLASS COLORATION AND COLOR TRANSITION (INTRODUCTORY TRAINING)

6 - 9 November 2023
14:00 - 17:30
Eindhoven (NL) and/or Online

In addition to its aesthetic purpose, glass coloration plays an important role. In packaging, color contributes to the protection of food and beverages against UV radiation. The coloration of building and automotive glazing filters IR radiation and reduces the need for air conditioning.

During this course, we will review the physics and chemistry at play in glass coloration, illustrated by industrial examples. Switching from one color to another is a complex transition that must be performed quickly without damaging production, while generating as few losses and defects as possible. Ideal transitions will be presented as well as operational limits and key parameters that must be monitored during color transitions.

Contents:

  • Definition of color, colorimetry, and color spaces
  • Influence of various coloring agents on glass color
  • Principle and limits of glass decoloration
  • Basics of redox, control, and reduced colors
  • Color transition: calculation and limitation
  • Operational parameter changes during the color change
Trainers
Johan Lotter
Johan Lotter obtained a master’s degree in chemical engineering from the University of the Witwatersrand. He worked at PFG building glass as a furnace engineer, technical expert, and manager of the technical department of two plants. He developed a large experience in raw materials, melting and floating process and defect analysis. He is now working as a CFD Engineer and trainer at CelSian.
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.
