When a dental patient is having one or more of his or her front teeth aesthetically improved, when a dentist cements thereon a porcelain veneer, which becomes a porcelain laminate extending across the front surface of the patient's tooth, the method steps followed and the equipment used have been improved. The improvements center both on obtaining more quickly and more accurately a noble metal foil matrix, which conforms to the front surface of the front tooth die of the patient, and on applying the porcelain ceramic slurry on the conformed noble metal material, to compensate for the shrinking of the porcelain during the firing thereof. The improved equipment is a forming machine which utilizes a constant pressure source of compressed air to move a piston in a cylinder, with the piston moving one metal die to contact another metal die, each die having an aligned rubber insert, and each rubber insert having an alike aligned receiving space. A patient's front tooth die with a pin, having its front face covered by a pre-sized noble metal foil, is placed within a thin plastic cover.
