ICG International Congresses On Glass

Every three years the ICG has a Congress, giving glass scientists and technologists a valuable opportunity to meet and disseminate information on glass science and technology. ICG Congresses typically attract 700 - 1000 attendees and up to 900 papers and posters. Special features include:

  1. Invited lectures reviewing major achievements in both the traditional fields of glass science and technology and in new glass applications: optics, photonics, elctronics, nanotechnology, coating technology, biotechnology, and composites
  2. Sessions organised by Technical Committees to review their work.

The XXVI CONGRESS (2022) will be in Berlin, Germany. A list of previous Congress venues is given below.

ICG Annual Conferences and other events in the Glass Field

In the years between its Congresses ICG organises an Annual Conference. Sadly the ongoing pandemic in 2020 has caused the cancellation of the conference planned this year in Krakow. The next in 2021 will take place in South Korea. Although shorter than the Congresses, several Technical Committees will organise sessions based on their key activities and many papers will be presented.

Other organisations also run Glass Conferences. To add an event to our list or edit an existing link please contact: j.m.parker@sheffield.ac.uk. Also do ask to add an electronic poster or a press release after the event on the 'Other News' section of this site.


One consequence of COVID-19 is that many people are turning to Webinars as a means of communicating. More information is available at the sites below:

1) DGG events

2) Glass International Programme

3) American Ceramic Society. Events included in conference list below.

4) British Glass Webinars on Net Zero production.
