Glass Analysis: Chemical and Physical Measurements

Glass is a crucial material in numerous applications. Today there is more glass in use than ever before. Glass is a critical design component encompassing environmental protection, appearance, safety, light transmission, and thermal management. The increasing importance and sophistication of glass means that more advanced analyses are needed to address manufacturing issues.


For over 50 years, the EAG Eindhoven lab has been involved in the entire value chain, from raw starting material to final products. We investigate the composition and quality of raw materials and production glass, give research and development support to glass factories during process optimization, glass tank wear-out studies, glass faults, verification tests and failure analysis investigations. EAG has unmatched expertise in that area.

About the Presenters:

royleclercqRoy le Clercq, Scientist, Material Science
Roy le Clercq studied Chemistry at the laboratory school at Sittard the Netherlands. In 1987 he joined the glass development department of Philips.
He has developed a broad knowledge in glass as a material, processing and characterization of glass. His expertise is broad and encompasses chemical, physical and optical characterization of glass for more than 30 years now.
Since 2018 Roy le Clercq became part of EAG.

jackhoppenbrouwerJack Hoppenbrouwer, Scientist, Material Science
Jack Hoppenbrouwer studied Chemistry at the IHBO in Eindhoven, The Netherlands. In 1989 he joined the Philips Glass Group. After melting small productions of new and special glasses he developed skills in glass fault analysis and glass-refractory interactions. Analytical skills include optical microscopy, Scanning Electron Microscopy (SEM) in combination with microanalysis (EDS, WDS and EBSD) and gas analysis (RGA).

In this webinar we will cover:

  • Chemical composition raw materials and glass
  • Physical characterizing raw materials, grain size and tap density
  • Physical characterizing glass, viscosity, density, thermal expansion, electrical resistance, refractive index and stress
  • Optical measurements on glass
  • Glass defects
  • Analysis of gas inclusions
