A method for manufacturing glass includes the melting of a mixture of raw materials constituting a melting bath including a source of silicon, a source of sodium, a source of boron and at least one source of calcium selected from a mixed oxide of calcium and at least one element selected from Si, Mg, Al, in particular a calcium silicate and/or a calcium aluminium silicate, and/or at least one source of magnesium selected from a mixed oxide of magnesium and at least one element selected from Si, Ca, in particular a magnesium silicate and optionally a source of aluminium selected from a mixed oxide of aluminium and at least one element selected from the group consisting of Si, Ca, Na, K, wherein the sources of calcium and/or of magnesium and/or of aluminium are natural mineral materials, that is to say are obtained from a natural geological medium and are unprocessed.
