A glance at the chart will tell you why engineers are specifying chemical equipment made from the new Ceratherms, the amazing dense-bodied, heat-shock resistant chemical stoneware. Here for the first time is a chemical stoneware, rugged and strong, a body that doesn't have to be handled with kid gloves, a body able to withstand abrupt changes in temperature up to as high as 750 degrees F. The new Ceratherms retain all of chemical stoneware's well-known advantages: ease of fabrication, low cost, unrivalled corrosionresistance, freedom from contamination. *With the exception of hot caustics and hydrofluoric acid, these new Ceratherms will handle all acids, alkalies and solvents in any concentration.

U. S. STONEWARE Since 1865 Ceratherm actually shows an increase in mechanical strength (note chart at right) when heated to 400 degrees F. and quenched— more than 100 degrees beyond the point where ordinary bodies begin to lose strength.
