Considering recent events related to COVID-19, the 81st Conference on Glass Problems will be held as a Virtual Conference rather than a live event, October 26–30, 2020. The Virtual Conference on Glass Problem continues to offer 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.
