pot melt
Japanese: ポットメルト
A technique in which colored glass is stacked in a fireproof pot with a hole in the bottom, allowed to flow down, and mixed on a shelf to produce free-form glass slabs. / Note: The process relies on the fluid’s self-forming properties. The principles of fluid dynamics are evident.

"Pot melt" is a technique in which colored glass is stacked in a refractory pot with a hole in the bottom, melted at a temperature of around 810–820°C, and allowed to flow down to create freely shaped sheets with blended colors on a shelf.
The flow rate depends on the fourth power of the pore diameter (Hagen-Poiseuille law), and the movement of the flowing fluid itself creates the pattern.
