🚨 Alert alert🚨
I just learned that somebody dropped out of what is going to be an amazing week at The Studio/ Corning Museum of Glass in early June.
I think they just waived the application process in an attempt to fill!

True story.
Thanks for considering!

Date: May 15
Times: 10am – 2pm PDT. (break(s) included)
Participants:10 max per session

I'm asked far too often how thick a dropout blank needs to be to be dropped "x" inches. The answer is a bit more complex than just a measurement but it's also much more interesting. Join Nathan for two online sessions and learn everything he currently knows about creating amazing kiln-glass Dropout Vessels. In the end you'll be able to tackle any mold with any blank at any height. You may never want a mold with a bottom again!

Please note: OnGrade Studio has been producing and using Flatop Dropout Rings for many years now (even before they were available to the public). It's almost all we know. This was never meant as a sales pitch but Flatop Rings will be relied upon during demonstrations and discussions.
