Excerpt from Properties of Some European Plastic Fire Clays It gives evidence not only concerning the vitrification tempera ture range (ff the materials but shows also when and to what extent the phenomenon of overburning takes place. By this is meant the formation of vesicular structure due to the evolution of gases. This is evidenced by the fact that during this stage the porosity again increases, since the clay becomes more or less spongelike in character. The usefulness of the clay is seriously lowered even during the incipient formation of this structure, as it is evidence that the clay has softened to a very great extent, and owing to the resumption of the greater porosity becomes more subject to the action of corroding slags or glasses. Fortunately in the presence of fine and coarser grained calcined clay of high refractoriness, grog, the formation of the vesicular structure is opposed by allow ing the gases to escape more readily, by the solution of the fine grained refractory clay with consequent stiffening, and by the mechanical effect of the skeleton of coarser grog particles. This condition is subject to regulation by the sizing of the grog, which makes necessary both the introduction of very fine particles and a series of coarser sizes. The adjustment of the sizes should be such that maximum density is produced in the dried state. It is specially important to keep in mind the function of the fine grog, a fact not as commonly realized as it should be. A plastic clay which shows some formation of vesicular structure need, therefore, not be condemned on this evidence alone. If, however, it persists in bloating when admixed with grog, its use becomes decidedly questionable. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
