Whatever you're cooking up, Colorceran® table-tops can take it

Whatever you're cooking up, Colorceran® table-tops can take it! Johns-Manville Colorceran resists attack by most acids, alkalies, solvents and dyes in common (and not so common) use. It's the ideal working surface for industrial, school and hospital laboratories. Colorceran is 100% inorganic—a tough, durable asbestos cement, surfaced with a ceramic-like mineral glaze. A 68 C&EN

unique manufacturing process forms a permanent, interpenetrating bond between the base material and glaze. Result: an attractive, almost impermeable surface that is unusually resistant to corrosion, physical abuse and thermal shock. J-M Colorceran is the only material of this type.

ceran and its advantages in the modern laboratory, write to Johns-Manville, Box 111, 22 East 40th Street, New York, New York 10016. • f^P* Also available in Canada. J l ^ ^ l Cableaddress:Johnmanvil. taw M l
