Q. How do you measure a cone after it has been fired?
A. There are two methods used to "measure" a cone. The first method requires the use of the Orton measuring template. The Orton measuring template is a plastic card used to measure the bending angle of large or self-supporting cones. The card will read bending angles of between 10 and 90 degrees. The fired cone is placed next to the card and the location of the tip of the cone indicates a bending angle. A cone bent to 90 degrees is considered to be properly fired.
The second method used to measure cones is the "clock method". This method requires that the indiviual translate the position of the tip of the cone to a clock face. The one o'clock position is for cones that have not bent at all, the six o'clock position is for a cone whose tip is touching the shelf. A cone in either the 5 or 6 o'clock position is considered properly fired.
