Glass shaping by gathering molten glass from a furnace on the end of a hollow steel pipe and blowing through the pipe to inflate the gather, while turning, shaping, and reheating the glass at a glory hole. The technique that has produced wine glasses, vases, decanters, perfume bottles, and the canonical free-blown glass forms of Venice and Bohemia for nearly two thousand years. Hot, fast, communal — most off-hand glass is made in two-to-four-person teams.
Workflow: (1) gather molten glass (typically soda-lime, working temperature 1100–1200 °C) from furnace on blowpipe; (2) marver (roll on graphite / steel marver to shape and cool); (3) blow controlled bubble; (4) shape with jacks, paddle, blocks; (5) reheat at glory hole every 30–60 s of work; (6) transfer to punty (solid rod) for opening top; (7) shape rim with jacks; (8) crack off, anneal at 480–520 °C overnight to relieve stresses. Cycle time per piece 5–60 minutes depending on complexity.
The bubble is one breath given to the glass. The glass repays the breath by holding the shape it was given before the breath cooled. In the moment between gather and finish nothing about the form is permanent — and then it is, suddenly and irreversibly, the thing it will always be.

Materials and processes for people who design and make things.
A local-first library of materials, processes, and applications, equal weight, citable everywhere. Part of the renato.design ecosystem — sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Form and matter, inseparable.
Half of teaching materials is teaching how the material is made into the thing. The standard subscription library was always light on that half. The wedge here isn't better samples or a prettier interface — it's treating Process as a peer entity, not a footnote.
