Glass Performance Days (GPD)
in Tampere, Finland June 13 -15, I will propose that fabricators use
window cleaning scrapers to test their own tempered glass for
fabricating defects that cause scratching.
GPD Finland is the world's largest international technical conference.
This will be my 3rd GPD presentation on this topic.

Why GPD Finland?
In house monitoring has been part of my dialog with fabricators dating back at least to 2005. The scraper test and inspection with a microscope is a way to get factory workers involved in quality control. It could be a management tool or the topic of a QA meeting. The key is to get them talking, and keep reminding fabricators that quality makes sense for them, too.
Part of my mission is to show that we understand - defects on the roller side are causing a tempered glass scratch crisis, not scrapers.
Also, window cleaners have discovered something the glass industry has known since 1993 - time-delayed tempered glass scratch growth - where scratches get more visible when you wait a few hours. (I first learned about it at GPD.) We now have doubts about guidelines warning cleaners to inspect for visible scratch, without warning about visible growth.
Here is the abstract for my
presentation, titled "Quality test for tempered glass roller side";
