raw materials blended and conveyed into the melting furnace to produce glass in the float glass process
Supplementary notes
*Zero to three percent.
**One to three percent.
Soda ash is added to glass to facilitate easier melting.
Limestone is added to glass to increase durability.
Dolomite is added to glass to improve the working and weathering properties.
There are a handful of raw materials that are used to produce glass made in the float process. Silica sand (SiO2) accounts for the majority of float glass' raw material inputs, with a ** percent share. Soda (Na2O) is the second-largest raw material input of float glass, at approximately ** percent.
