All About Glass

The process of making float glass is so amazing that it's almost akin to magic. Raw materials are inserted from one end and from the other end, specifically cut plates of glass start to emerge at a whopping rate of six thousand tons per week. The final product is destined to be used in variousGet price

How to Make Glass (with Pictures)

An alternative is broken glass in place of sand if it is available. Some glass will begin to get soft at around 1100-1200 degrees and go liquid at around 1400. But to make glass from sand requires a much higher heat for a longer period of time along with other materials besides sand.Get price

Answers for Sheet glass manufacture: the float

Glass, which has been made since the time of the Mesopotamians and Egyptians, is little more than a mixture of sand, soda ash and lime. When heated to about 1500 degrees Celsius (C) this becomes a molten mass that hardens when slowly cooled. The first successful method for making clear, flat glass involved spinning.Get price

The making of glass fiber

The glass fiber process. Textile-grade glass fibers are made from silica (SiO 2) sand, which melts at 1720C/3128F.SiO 2 is also the basic element in quartz, a naturally occurring rock. Quartz, however, is crystalline (rigid, highly ordered atomic structure) and is 99% or more SiO 2.If SiO 2 is heated above 1200C/2192F then cooled ambiently, it crystallizes and becomes quartz.Get price
