Vitressa, the Arrested Glassblower Mug
A glass is a liquid whose relaxation became too slow to follow on experimental timescales: kinetically arrested, not in equilibrium.
The joke: Physicists know glass is out of equilibrium; do NOT use the cathedral-window myth. The slogan on the mug reads NOT FINISHED. JUST A GLASS.
