Getting Started
A guide to GlassPosi
GlassPosi is a place to share the wonder within craft — where makers and observers alike can stay, holding their questions. It's built in Japan, and made readable in your language.
First step
Not sure where to begin? Start here.
The firing-schedule generator builds a safe firing schedule from just the glass and thickness you choose — likely a world first. It’s free to use while you’re signed in.

Learn, make, talk, gather.
Learn
Recorded lectures, the glossary, and the glass catalog — take the techniques and words of glass one at a time. Come away holding a question, more than an answer.
Make
Deepen your practice with the firing-schedule generator and making hints, and keep it all in your studio journal — dates, the glass you used, firing curves, photos in progress and finished. Even what didn't go well is an asset here.
Talk
Bring a making struggle to “Rei listens” and be accompanied. Share what you're thinking and trying in Rei's notes and the monthly meetings.
Gather
Meet members in “People by the water,” and see work born here in the shared photos. One person's making becomes everyone's hint.
