The invention provides a making method of laminated tempered glass, and belongs to the field of the making of toughened glass. The making method comprises the following specific steps of firstly, preparation of materials for the laminated tempered glass: common glass, an electric heating wire, laminated-layer glass cement, a constant-temperature controller and mercury; afterwards, toughening treatment of the common glass: taking a piece of common transparent float glass to carry out toughening in the ways of interval heating and cooling treatment, in a heating process, and when a certain temperature is controlled, flatwise paving the electric heating wire on the surface of molten glass; afterwards, mirror surface treatment of the toughened glass: uniformly coating the surface of the toughened glass with the mercury, so as to prepare the mirror surface of the toughened glass; afterwards, cleaning treatment of the common glass: cleaning the common glass; afterwards, lamination treatment:spreading a lower cement sheet layer on a bottom layer of the well cleaned common glass and meanwhile spreading an upper cement sheet layer on a surface layer of the well treated common glass; afterwards, crushing treatment of the toughening glass and connection of the constant-temperature controller: carrying out solidification treatment of a well pasted glass product, and afterwards, carrying out spontaneous detonation treatment.
