While the ultimate analysis, therefore, fails to indicate definitely what compounds are present in the clay, still there are many facts to be gained from it. The ultimate analysis of a clay might be expressed as follows : Silica...

As a matter of fact, however, repeated tests with a thermoelectric pyrometer demonstrate that the cones commonly fuse close to the theoretic temperatures. Manufacturers occasionally claim that the cones are unreliable and not satisfactory, forgetting that their misuse may often be the true reason for irregularities in their behavior. It is unnecessary, perhaps, to state that certain reasonable precautions should be taken in using these test pieces.

It is always well to put two or more cones of different numbers in the kiln, so that warning can be had, not only of the end point of firing, but also of the rapidity with which the temperature is rising. In determining the proper cone to use in burning any kind of ware, several cones are put in the kiln, as for example, numbers .08, 1 and 5. If .08 and 1 are bent lover and 5 is not affected, the temperature of...
Seite 29 - As the temperature rises the cone begins to soften, and when its fusion point is reached it begins to bend over until its tip touches the base. For practical purposes these cones are very successful, though their use has been somewhat unreasonably discouraged by some. They have been much used by foreign manufacturers of clay products, and their use in the United States is increasing.
