A bstract The construction and operation of a high‐temperature electric load‐test furnace are described. Temperatures to 1900°C. can be obtained with a spiral graphite heating element which has reasonable voltage and current characteristics. Neither a vacuum nor a special atmosphere is used inside the furnaces. Life and operating data are given.
