Prince Rupert
Prince Rupert's drops (also known as Dutch or Batavian tears) are toughened glass beads created by dripping molten glass into cold water, which causes it to solidify into a tadpole-shaped droplet with a long, thin tail. These droplets are characterized internally by very high residual stresses, which give rise to counter … 더 보기 Prince Rupert's drops are produced by dropping molten glass drops into cold water. The water rapidly cools and solidifies the glass from the outside inward. This thermal quenching may be described by means … 더 보기 The process for the production of toughened glass by quenching was probably inspired by the study of the drops, as it was patented in England by Parisian Francois Barthelemy Alfred Royer de la Bastie, in 1874, just one year after V.
