Where when and by whom was unbreakable glass invented?

There is no such thing as 'unbreakable' glass, however, bulletproof glass is actually just normal glass, but, it has a thin plastic sheet, because, glass on its own is strong enough to stop glass, it'll just shatter, The plastic sheet stops it from shattering.

Can a spear go through bulletproof glass?

A spear is unlikely to penetrate bulletproof glass, which is designed to withstand high-velocity impacts from bullets. The thickness and material composition of bulletproof glass provide significant resistance to penetration. While a spear can deliver considerable force, it typically lacks the concentrated energy that a bullet generates upon impact. Therefore, the effectiveness of a spear against bulletproof glass would be minimal.

Who invented bulletproof plexiglass?

Bulletproof plexiglass was invented by a chemical engineer named Wilhelm Rohm in the early 20th century. Rohm developed the material as a transparent plastic alternative to glass with enhanced durability and impact resistance, making it suitable for ballistic protection.


What was needed to make bulletproof glass?

Alternating layers of glass and plastic resin. Truly bulletproof glass must be at least 4 to 6 inches thick! I've seen samples of such glass from WW2 bombers in museums. Modern bulletproof "glass" probably uses plexiglass plastic instead of real glass though. Note: a thick enough piece of ordinary glass is bulletproof by itself. Telescope mirrors (several feet thick) have been shot and although damaged the bullet did not pass through and after removing the bullet, drilling out the hole, and painting the inside of the hole black the telescope was returned to operation with no detectable loss of function.
