• "Likewise, the same causes of cooling that operate in the everyday domain will bring objects from pyrometric temperatures down to everyday temperatures; that is precisely what happens in calorimetric pyrometry (or, when we simply leave very hot things out in cold air for a while)."
• "A knowledge of the fundamental principles of pyrometry, or the measurement of temperatures, is quite necessary for one engaged in the heat treatment of steel."
• "This method is still sometimes used, but for uniform results, a platinum ball, which will not scale or change in weight, is necessary, and the cost of this ball, together with the slowness of the method, have rendered the practice obsolete, especially in view of modern developments in accurate pyrometry."
