The invention provides a process for preparing a porous glass, comprising mixing borosilicate glass powder with calcium carbonate particles to form a mixture, sintering the mixture at a temperature in the range from 750 to 850° C. to obtain a sintered body, cooling the sintered body and leaching calcium carbonate from the cooled sintered body with the aid of an acid. The invention also provides a process for the preparation of one or more alkaline earth metal silicates by reacting a vitreous material and an alkaline earth carbonate, optionally in the presence of a transition metal or post-transition metal oxide, at a temperature lower than 1200° C., to form a composite consisting of one or more alkaline earth metal silicates and a residual glass, and optionally recovering the one or more silicates.
