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?
