Description
Float Glass is a
sheet of glass made by floating molten glass on a bed of molten
metal, typically tin, although lead and various low melting point
alloys were used in the past. This method gives the sheet uniform
thickness and very flat surfaces.
The ingredients
for making it are typically about *3 percent silica (essentially
sand), soda ash (about *3 percent) and limestone (around nine
percent). Soda ash is produced worldwide in huge amounts, and
limestone and silica are abundant quarry products. These elements
are weighed and mixed into batches, together with recycled glass,
known as “cullet,” which accounts for anywhere from *5 to *0
percent of the mixture. The ingredients are melted together at high
temperature, which uses a significant amount of fossil fuel energy.
The cullet content reduces the amount of energy needed, thus
qualifying as a green measure.
