No, they aren't. But some old tubs were made of cast iron which is quite strong as it is.
The Scientific name for Bullet Proof Glass is Bullet Resistant Glass. It is referred to as Bullet Resistant Glass in the Industry as there is no such glass that can stop every bullet. A series of bullets that hit within a small area of the Bullet Resistant Glass will eventually project right through the glass.
Composites means which is made of composition of two constituents where as synthetics is the combination of two or more parts, composites having constituents of different physical and chemical properties, where as in case of synthetics it can have same chemical or physical properties,in case of composites the ratio of material is maintained but it can not be in case of synthetics...e.g of synthetics is plastic, or composites is concrete
Pyrex is the trade name of a Corning low thermal expansion glass. All Pyrex is glass, not all glass is Pyrex.
Some composites might contain metal (e.g. steel wires like used in tires), but no composites are not metals. A few typical composites are:fiberglass & epoxy resincarbon fiber & epoxy resincarbon-carbon (a very high temperature composite made by baking carbon fiber & epoxy resin until the epoxy resin carbonizes)etc.
face soap is for face and bath soap is for bath
Kevlar fabric
Bullet proof vests are made from many layers of woven,laminated fibers ,metal and ceramic plates.
Kevlar is one of the best and well known bullet proof materials. it was originally made to be a material to make a tire but when they made it it was stronger than they thought it would be.

Bullet Proof Glass (usually 2-4 inches), Hard Metals (usually1-3 inch) And Other Bullet Proof Materials.
Silicone carbide ceramics, and laminates.
no acshally it is bullet pruff vests used to be made of whale shark skin

A series of bullets that hit within a small area of the Bullet Resistant Glass will eventually project right through the glass.
Bulletproof or "bullet resistant" vests are usually made from Kevlar. However they may also be made from Lexan or carbon fiber composites. It is also filled with three or four layers of those material.
ruber and kelver the same material used for bullet-proof vests
Composites are made from two constituent materials. The two materials have different chemical and physical characteristics from one another, and the composites they form have different characteristics from both of them.
Police vests are made to be bullet-proof. In the event of a shootout with a possible suspect or criminal, this could save a police officer's life. Police bullet-proof vests are made up of several layers of laminated fibers. Metal and ceramic plates can also be embedded in the vest, offering further protection.
