Firing Speed and Pyrometric Cones |
Firing Speed and Pyrometric Cones During the last 100 – 200 degrees, the firing rate affects the bending temperature of a pyrometric cone. The faster the rate, the higher the temperature when the cone bends. But the firing speed before the last 100 – 200 degrees has little or no influence on the final temperature of the pyrometric cone. The exception is an extremely fast firing that bloats the cone. I have seen that happen in the Paragon QuikFire, which can reach 1000°F in five minutes. When the cone bloats, it loses its accuracy.
