The solidification point of calcia which has been distributed by the Commission on High‐Temperature and Solid‐State Chemistry of the International Union of Pure and Applied Chemistry was measured by digital pyrometry using an arc imaging furnace. The solidification point was determined to be 2899°C with ±3°C as the standard deviation for this sample. The reliability of this solidification point was determined to be within ±17°C based upon discussions of the measuring system and the material.
