Company's Source of Asbestos As Keasbey & Mattison Co. controls its source of crude asbestos, owning the Bell Asbestos Mines at Thetford Mines, P. Q,, Canada, perhaps the world's most productive mines of high-grade Chrysotile Asbestos, this company is assured of a constant supply of long-fibred asbestos so necessary in making a thoroughly efficient insulation. K &.M 85 Per Cent Magnesia "Featherweight" Sectional Coverings and Blocks Keasbey & Mattison Co. were the originators of 85 Per Cent Magnesia Covering, so called because it is composed of about 85 per cent basic carbonate of magnesia and 15 per cent-of asbestos fibre. The magnesia is bound together with the long-fibred asbestos, giving it the necessary structural strength. K & M 85 Per Cent Magnesia "Featherweight" is very light in weight, fireproof and extremely durable. It will not injure piping and has a-very high, insulation value. Impartial expert engineering tests showing its superiority will gladly be sent upon request. K & M 85 Per Cent Magnesia "Feather weight" Sectional Coverings are canvasjacketed and 36 in. long per section. They are. made in all standard and double standard thicknesses, 2-in. thickness, and 3-in. broken joint construction, and also in combination with Ambler High Tempera ture Insulation. Ambler High .Temperature Sectional Covering and Blocks -Recommended for temperatures in ex cess of 700 deg. fahr. These coverings are composed chiefly of asbestos fibre, bonded with inorganic binders found by experience to be best fitted for this class of insulation. These coverings have a high insulating value and will withstand temperatures up to 1200 deg. fahr. Furnished in same moulded shapes and thicknesses as 85 Per Cent Magnesia Coverings and Blocks. Ambler Asbestos Cement Composed of asbestos fibre and inert materials having high insulating value, being superior to ordinary asbestos cements and surpassed only by 85 Per Cent Magnesia Cement. r Ambler Asbestos "Velvet" Cement A fire-resisting and waterproof cement which gives a hard, smooth and beautiful., finish to cement and block work, fittings-^ and large or irregular steam surfaces. Furnished in 100-lb. bags. Ambler Asbestos Paper, Textiles, Gaskets and Boards Ambler Asbestos Aircell Coverings-- These are composed of various thicknesses of. asbestos corrugated paper, each ply being about in. thick. These thick- nesses united form a covering which is light, fireproof and very satisfactory for low domestic heating and piping insula tion.
