A method for calcining dolomite in which the pressure of carbon dioxide is controlled is described. Less than ½ of one per cent of lime is liberated. Material was calcined in ton lots using external heating. Two types of retort were used: wrought iron and fire clay. Floors were laid from the material so calcined and physical tests made on the calcine to determine its availability as a stucco material. The effect of time, temperature, and pressure of carbon dioxide upon three types of dolomite is brought out. Dolomites are either double salts or solid solutions or mixtures of the two. The effect of lime and silica is pointed out. Dissociation, tensile strength, volume change, time of set, and weather test data are given.
