Behind the finished vase are the spinning tools used to shape the metal. Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. [1] Spinning can be performed by hand or by a CNC lathe.
For example, for the standard ferromagnetic Potts model in , a phase transition exists for all real values , [7] with the critical point at = (+). The phase transition is continuous (second order) for 1 ≤ q ≤ 4 {\displaystyle 1\leq q\leq 4} [ 8 ] and discontinuous (first order) for q > 4 {\displaystyle q>4} .
Melt spinning is a metal forming technique that is typically used to form thin ribbons of metal or alloys with a particular atomic structure. [ 1 ] Some important commercial applications of melt-spun metals include high-efficiency transformers ( Amorphous metal transformer ), sensory devices, telecommunications equipment, and power electronics.

Joseph Bendik first noted the interesting motion of the spinning disk while working at Hughes Aircraft (Carlsbad Research Center) after spinning a heavy polishing chuck on his desk at lunch one day. The apparatus is a dramatic visualization of energy exchanges in three different, tightly coupled processes.
