Getting Started
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.
GlassPosi has three levels of access. Here is what each one opens.
Visitor (no account)
Look around freely.
Free member (just sign up)
Everything above, plus:
Paid member
Write, talk, and see everything.
Posting (comments, questions, maker notes) is for paid members. Juku members, ambassadors and marketers get the same access, fee-exempt.
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. Building and saving a schedule is a paid member feature; free members can open the page and look around.

Take a guided tour
Four ways to spend time by the water. Press “Take the tour”and we’ll walk your my-page with you, introducing each feature in a speech bubble — then straight on to the next.
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.
Take the “Learn” tourMake
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.
Take the “Make” tourTalk
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.
Take the “Talk” tourGather
Meet members in “People by the water,” and see work born here in the shared photos. One person's making becomes everyone's hint.
Take the “Gather” tourThe tours run on your my-page (for members; sign-in required). You can also open each feature’s own guide from its page.
