🧪 Glass Art Simulation

Interactive molten-glass gob on a spinning blowpipe: heat it to drop its viscosity (a real Vogel-Fulcher-Tammann curve), inflate it with blow pressure, and spin the pipe to fight gravity sag with centrifugal force, exactly as a glassblower does.

This simulator models a real gob of molten glass on the end of a blowpipe as a deformable mass-spring shell whose stiffness, damping and permanent-flow rate are all driven live by a genuine Vogel-Fulcher-Tammann viscosity curve. Heat the glass and it droops and flows like a real hot gather; cool it and it locks into whatever shape it currently holds. Blow pressure inflates the shell outward through every triangle's own surface normal, exactly like breath through a pipe, while spinning the pipe applies a real centrifugal pseudo-force (F = mω²r) that fights gravity's pull and keeps the piece symmetric instead of drooping to one side — the same reason a glassblower never stops turning the pipe.

⚙ Under the hood

This simulation demonstrates the physics of glass forming techniques. It explores concepts like thermal expansion, viscosity, and surface tension as they relate to shaping molten glass into various forms.
