In light of recent events related to COVID-19, the 81st Conference on Glass Problems will be held as a virtual event rather than a live event, October 26–30, 2020.

We will be offering a robust content rich program, symposium, and short courses that we are sure you will find valuable. Conference presentations will be recorded and available as downloads for conference attendees until November 13. In addition, conference attendees will be sent a link where they can download technical manuscripts of the main conference proceedings.
