Book Description
Excerpt from The Properties of Some Stoneware Clays The work was begun in June, 1917, before the Bureau of Mines ceramic experiment station at Columbus, Ohio, was established, and was later continued at that station. The writer is indebted to A. S. Watts, quarry technologist of the bureau, under whose direction the work was undertaken. The Pennsylvania geological survey assisted in obtaining the clays in cluded from that State. The samples of Ohio clays and the sections of the beds sampled were supplied by Mr. Wilbur Stout, of the Ohio geological survey.

Excerpt from Clays Their Occurrence, Properties, and Uses: With Especial Reference to Those of the United States Since the work is not one treating in detail of the manufacture of clay products, this part of the work has not been enlarged; indeed, it was included originally simply for the purpose of giving a brief idea of the processes Which clays had to pass through in their con version into ceramic products.

Excerpt from Relation of the Composition to the Properties of Clays Mineralogical analyses of a large number of clays have shown that there are three important groups of clay minerals. Clays, therefore, generally are composed of a member or members of the three groups. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The Useful Properties of Clays As soon as a greater number of individuals among our people become interested in the properties and possibilities of our native clay bodies, development is sure to follow. Clay working is neither so difficult nor so expensive but that in some cases objects of art have been molded in the home and burnt in private kilns. On the other hand success is attained only at the price of diligent study and persistent effort. It is with the hope that the dissemination of knowledge concerning the useful properties of clay will lead to a wider popular interest in their study and use, that this article is written. Formation Of Clays. Clay may be defined as an earthy deposit, found on or below the surface, which when finely ground and mixed with water forms a moldable or plastic mass and can be burned to a hard, stonelike substance after drying. The original crust of the earth was of course formed of the rocks which crystallized from a molten magma. These crystalline rocks of igneous origin underwent gradual crumbling and decay caused by the varied actions of the elements. It is probable that only students of rock structure realize how steadily and continually rocks are undergoing secondary changes, and decay. "Enduring as the rocks" is an expression of merely relative truth. When rocks crumble the resulting material may be found either heaped up in place, in which case they are known as residual deposits, or the fine material may have been picked up in suspension by moving waters, sifted out and deposited at some remote place in beds or layers forming sedimentary deposits. These deposits once formed have been, in some cases, acted on by tremendous forces in the course of the great geologic periods. Folded and buried under great crumplings of the earth's crust they have been to varying degrees subjected to heat and pressure and have thus become metamorphosed. Consolidated into sedimentary rocks and shales they become again subject to decay. Changed and disintegrated, now acted on by percolating waters, in which it is known that many of these crystalline minerals are distinctly soluble, or again subjected to acid or alkaline solutions, as the case may be, it is little wonder that every useful earthy deposit found by man on the surface of the earth is to a certain degree unique in its properties, requiring special study and treatment in order to insure the highest degree of success in its working. Clays of nearly the same chemical composition and of similar physical texture, owing to some slight modification will yield entirely dissimilar results in mixing, molding, and firing.

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.

Book Description
Excerpt from The Effect of Heat Upon Clays The Effect of Heat Upon Clays is a subject of vital ln terest to every clayworker. 'tis said there are no two clays alike. Each clay has properties peculiar to itself, hence to insure the best results in product and economy in manufac ture, each clay must be studied carefully and treated in a manner best adapted to develop the highest grade of ware, whether it be brick, tile or pottery, at the lowest cost. With a view of aiding clayworkers to solve some of the many dim cult problems incident to the variation in clays, Prof. A. V. Bleininger some years ago prepared a treatise on this sub ject for the clay-worker, which was published in serial form. The subject is of such prime importance that the matter has been revised by the author and is now pre sented in book form for library and reference purposes.

Book Description
Excerpt from The Natural History of Clay Both as raw materials and in the form of pottery, bricks, tiles, terra-cotta and many other articles of use and ornament, clays are amongst the most important rock products. Yet the origin of the substances we know as 'clay, ' the processes occurring in its formation and the causes of some of the most important of its characteristics are of such a nature that it is remarkable that its use should have become so extended in the arts and sciences, while we know so little of its properties when in a pure state. In the following pages an attempt has been made to state in a simple form an outline of our present knowledge of the subject and to indicate the problems which still lie before us. The experimental solution of these problems is rendered peculiarly difficult by the inertness of the materials at ordinary temperatures and the ease with which the clay molecule appears to break down into its constituent oxides at temperatures approaching red heat or as soon as it begins to react with alkaline or basic materials. Another serious difficulty is the highly complex nature of that property known as 'plasticity' to which many clays owe their chief value.
