GLASS COLORATION AND COLOR TRANSITION (INTRODUCTORY TRAINING)

6 - 9 November 2023
14:00 - 17:30 CET
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
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.
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.
