Upon purchasing an OnGrade Adventure you will reserve a custom/private workshop at OnGrade Studio in Portland, Oregon, USA. You will then begin a conversation with Nathan to determine exactly what The Adventure will involve. Any workshop or combination of workshops is on the table. Focus on one topic or mix-n-match curriculum (to a point)**. No matter what, an entertaining, top notch education in a professional glass studio is in your future.

If you have a glassy friend, most Adventures can be expanded to include another person. Both visitors must purchase a spot.

I can usually slide The Adventure a day or two in either direction if including a weekend is important to you.

Tuition includes access to professional tools and all necessary materials* for most classes.

Currently scheduling for December 2024 AND BEYOND. No refunds. Only a sincere promise to reschedule at a time that works for both parties if a cancellation is necessary.

*However: Certain topics may require an extra studio fee if, for example, we decide to pull murrine on all 5 days. Any adjustments will be fair and discussed ahead of time.

**Most topics can be combined while preserving educational integrity. There is probably a combination or two that won't work well together. Please note that I will never teach how to reproduce some else's work or present another artist/instructor's workshop**
