2. Strength of glass - Wikipedia

   en.wikipedia.org/wiki/Strength_of_glass

   Glass fibers have a much higher tensile strength than regular glass (200-500 times stronger than regular glass). [7] This is due to the reduction of flaws in glass fibers [8] and the small cross sectional area of glass fibers, constraining maximum defect size. [2]

   Bulletproof glass of a jeweler's window after a burglary attempt. The Mona Lisa behind bulletproof glass at the Louvre Museum. Bulletproof glass, ballistic glass, transparent armor, or bullet-resistant glass is a strong and optically transparent material that is particularly resistant to penetration by projectiles, although, like any other material, it is not completely impenetrable.

   The result is a material that is both stronger and more insulating than glass, with better biodegradability than plastic. "We were very surprised by how transparent it could go," said Liangbing Hu ...

6. Cast acrylic - Wikipedia

   en.wikipedia.org/wiki/Cast_acrylic

   Cast acrylic has a better ability to be reworked hot and it is known for its superior surface finish and optical properties. Also cast acrylic is more scratch resistant than extruded acrylic. Cast acrylic is also preferred over extruded in applications that require machinings, such as turning on Engine Lathe or milling/drilling.

7. Tempered glass - Wikipedia

   en.wikipedia.org/wiki/Tempered_glass

   Tempered glass is sometimes known as Bastie glass after de la Bastie. In 1877 the German Friedrich Siemens developed a different process, sometimes called compressed glass or Siemens glass, producing a tempered glass stronger than the Bastie process by pressing the glass in cool molds. [17]
