Windscreens in small motorized vehicles are commonly made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small airplanes and helicopters. The light weight of polycarbonate as opposed to glass has led to development of electronic display screens that replace glass with polycarbonate, for use in mobile and portable devices.
In 1892, Rudolf Von Wagner distinguished soda, potash, double (soda and potash), and fixing (i.e., stabilizing) as types of water glass.

Some glasses such as volcanic glass are naturally occurring, and obsidian has been used to make arrowheads and knives since the Stone Age.
Glass filler materials come in a few diverse forms: glass beads, short glass fibers, and long glass fibers. in plastics by tonnage. [ 6 ] Glass fibers are used to increase the mechanical properties of the thermoplastic or thermoset such as flexural modulus and tensile strength, There is normally not an economic benefit for adding glass as a ...
There are many forming techniques to make ceramics, but one example is slip casting. This is where slip or, liquid clay, is poured into a plaster mould. The water in the slip is drawn out into the walls of the plaster mould, leaving an inside layer of solid clay, which hardens quickly. When dry, the solid clay can then also be removed.

Sand casting involves the use of hot molten glass poured directly into a preformed mould. [5] It is a process similar to casting metal into a mould. The sand mould is typically prepared by using a mixture of clean sand and a small proportion of the water-absorbing clay bentonite. Bentonite acts as a binding material.
