BUBBLE DIAGNOSIS – INTRODUCTORY TRAINING

14 - 15 April 2026
14:00 - 18:00 CET
ONLINE

From cause to cure, master the science and solutions for bubble control.

Bubbles and seeds are leading causes of production rejections in glass manufacturing. This course addresses the root causes of these defects, covering everything from batch-to-melt conversion to downstream gas sources during forming. It explores the chemical and physical processes that drive bubble formation and provides strategies for effectively managing bubble-related issues, ensuring superior glass quality throughout production.

You should attend if you are interested in:

  • Batch decarbonization, bubble formation, and interaction with the glass melt
  • Bubble ascent and glass flow velocities
  • Gas solubility, chemical fining and refining
  • Physical fining
  • Reboil mechanisms
  • Downstream sources of gases and forming bubbles
  • Practical guidelines in case of bubble upset

What you take away:

  • Have a step-by-step approach to detect and resolve bubble problems
  • Understand the many origins of bubbles
  • Comprehend the numerous chemical and physical phenomena that contribute to bubble removal
  • Understand how experimental and numerical tools can help identify and resolve root causes in the event of a bubble crisis

Level of seniority
This training is meant for batch, furnace and quality team members who must deliver good quality glass, support and make decisions in case of a bubble upset. They will get a better understanding of the phenomenon at stake and sharper troubleshooting abilities.

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.
