Tests were made of the electrical resistivity of twelve commercially used special refractory brick at temperatures up to 1300°C. Standard 9‐inch brick were tested using apparatus which is standard equipment and readily obtainable. Temperature lag was eliminated by constant heating over a prolonged period of time at given temperatures. Results obtained indicate a decrease in resistivity with prolonged heating for some classes of refractories. Those refractories composed of minerals of the same petrographic classification appear to undergo the least change.
