    MATERIALS FOR CROWN AND BRIDGE WORKERS' APPLIANCES STEEL The steels which we use in dentists' tools are made from formulas which were carefully preparlto'i provide just the qualities needed for the work. Not a rod of steel is accepted from the makers Itil it is tested and found to meet the requirements. The tempering is skilfully done to give eac'jn. strument the degree of hardness best adapted to its work. CORUNDUM The abrasive power of Corundum was for many years the mainstay of dentists for the trimminfl crowns and roots and other thousand and one uses which is found in practice. The various aj - ances are formed by incorporating Corundum powder with a binder and molding the compound ] 3 the requisite forms, which are then hardened. Corundum Disks, Wheels, and Points should always be used wet, because the materials used 1 binders, while insoluble in water, are susceptible to heat. Running Disks, etc., dry would develop s ficient heat to soften the binder and render the appliance useless. Keeping them wet eliminates t risk. Disks and Points are mounted on mandrels with shellac. OEM The material known as Gem has won a high place because of its great abrasive power and i durability. It cuts fast and clean. The appliances of Gem or hard baked, a process which apparent intensifies the original abrasiveness of the material fitting them for hard, rough work. They ai uniform in texture and continue effective working till worn down to the mandrel. A great advantage of the Gem appliances is that they cut rather better dry than wet. They d not need to be pushed; simply holding them to their work will result more satisfactorily. Gem Points are mounted on mandrels with cement,—not with shellac. DIAMOND Diamond tools are, when rightly made and properly used the perfection of clean, sharp, rapid- cutting devices for dentists' use. The Diamond Drills, Disks, Wheels, and Points which we sell are made in our own factories, and every tool is tested before it is put into our sales stock. They are made right. In use, they must be kept wet, and they must not be pushed. Reversal of either of these rules will ruin any diamond tool ever made. Diamond tools are expensive, and dissatisfaction will surely result from hasty or careless use. On the other hand, as evidence that with the right sort of manipulation, they may be depended upon, we frequently drill several hundred cavities in porcelain teeth with a single Diamond Drill. Trade-Mark VULCARBO Reg. in TJ. S. Pat. Off. Vulcarbo is our trade name for a compound of Soft Rubber loaded with Carborundum and then vul- canized in the forms sold. The mixing is so carefully and thoroughly done that we are assured of a vulcanized product which is homogeneous in texture, free from soft spots. Vulcarbo is stiff without being brittle. It affords the fullest cutting power of the Carborundum with a tough structure which prevents breakage under any fair conditions of use. It is extremely dur- able; wears uniformly down till there is no more usable surface. The molds are made with the utmost nicety. Disks and Points are perfectly circular,—symmetrical in shape. When mounted prop- erly they run true. CARBORUNDUM With the fierce cutting quality of Carborundum most dentists are familiar. In the manufacture of Carborundum Wheels, Disks, and Points, we have simply applied our usual methods; have taken the best quality of the raw product and have made it up in the best manner. Our Wheels, Disks, and Points are properly molded, are uniform in sizes, are dense and strong.
