# Cold process to make glass

Since glass is a mix of silicates of sodium and calcium produced by heating or fusing together $$\ce{Na2O}$$ (Lewis base) with sand or $$\ce{SiO2}$$ (Lewis acid). Since $$\ce{Na2O/NaOH(aq)}$$ is a strong base and is used to create water glass(es)$$(\ce{Na2SiO3},$$ $$\ce{Na_xSiO_y}$$ etc.).

Is there some procedure in place to create glass by mixing (a base rich) water glass at room temperature with calculated amounts of $$\ce{CaO}$$ in mould to prepare float glass of definite shape without heating or mild heating?

• Bulk materials are not always easily created from the components. For example, is it easy to create bulk iron from iron filings with heating?
