Characteristics :
General Description :
Pyrometric cones are used to determine the combined effect of temperature and time, usually called Heat work in the firing of ceramic wares. The physical and chemical changes in the cones resulting in deformation are similar to those taking place in the ware being fired. This phenomenon is an important factor contributing to the usefulness of pyrometric cones for the following purposes :
The usefulness of pyrometers is limited, in that they do not provide adequate information or evidence of the combined effect of time and temperature such as is obtained from cone readings. The temperature data obtained from pyrometers is used either to note advances in kiln temperatures at the thermocouple location or to note whether a definite temperature is being maintained at a given point.
Preparation :
The use of Cones :
1). Deform at right angles to the axis of the plaque2). Deform along the axis of the plaque3). Deform at an angle (viz. 45°) to the axis of the plaque. If the cones are so set that one may face an another, the higher cone number should fall on the lower number cone.
