312 makes an intaglio modeled tile, the effect of which, when filled with glaze, is that of a photograph on a smooth surface of clay. The different depths of the engraving regulate the degree of shading, and portraits of individuals have been executed with great fidelity. It has been mainly through the intelligent management of Mr. George A. Stanbery, the general superintendent, with the assistance of Mr. Karl Langenbeck, the efficient chemist of the company, that such marked success has been achieved. The



modeling and casting of the dies are the work of Mr. Hermann Mueller, formerly of Coburg, who studied in the Industrial Academy and Preparatory Art School of Nuremberg, and in the Art Academy of Munich. For geometrical designing of encaustic tiles used in flooring and wainscoting the factory employs several competent architects.

The works were projected in 1875 for the manufacture of floor tiles, but in 1880 enameled tiles were added to the products of the factory, and at the present time eleven large kilns are in operation. The city of Zanesville has recently donated a tract of thirty acres to the company, on which an extensive plant is now being erected which will include twenty-eight kilns, to be operated in addition to the present establishment.

The Trent Tile Company, of Trenton. N. J., established about 1883, is now making dull lustered tiles in alto-relievo, which process has been patented. This style of finish forms a striking contrast to the glazed and enameled varieties also made here.
