The Dental cosmos . ING. A PERFECT GOLD COVERING FOR RUBBER APPLIED FOR. In this Gold Lining we claimadvantages over others as fol-lows : The Gold is applied in onepiece to the surface to be cov-ered. No extra care is required inpacking the flask. The Lining is composed otchemically pure Gold with athin covering of pure union between the rubberplate and the Gold Lining ismechanical; the sulphur in therubber when set free by theaction of vulcanizing corrodingthe surface of the silver, towhich the rubber adheres per-fectly. If the rubber plate is coveredon both sides it is tougher whenvulcanized, for the reason that during this process the pressure against themetal gives the plate a surface more dense than it will have if vulcanized incontact with plaster. The sheets are of the thickness of No. 20 foil, and each book containsabout forty-eight (48) square inches,—more than enough to cover six ordinarysize plates on one side, or four plates on both sides. Price per package 38. SOLID STEEL PLIERS AND NIPPERS. Flat. Front.
