materials met with such approval by the trade that a larger 
plant and improved facilities for manufacturing were found 
necessary, and in 1907 land was purchased at Sheridan, Pa., 
and a factory built and equipped. About eighteen months 
after completion, this plant, together with a large quantity 
of finished products and raw material, was entirely de- 
stroyed. Undaunted by this misfortune, the owners im- 
mediately set to work and in January, 1909, a new plant, 
considerably enlarged, built in a very substantial manner, 
and completely equipped, resumed operation. The business 
since that time has been incorporated and operated success- 
Fully as The Vitro Manufacturing Company. 
Some of the materials manufactured are prepared en- 
amels for steel, cast iron and copper, coloring oxides, es- 
pecially prepared to give enamels and glass any desired 
color or shade; enamel white and vitrozircon, materials 
developed to replace the expensive oxide of tin in white 
enamels; vitrifiable colors and gold compounds for decorat- 
ing glass, pottery and tiles; ceramic chemicals such as 
chromium oxide, cadmium sulphide and uranium products 
ased as coloring mediums for the glass, enamel, pottery and 
rement industries. 
All raw materials and finished products are manufac- 
tured and controlled by chemical and ceramic methods. In 
addition to a well equipped plant, this company has re- 
cently built and equipped a laboratory for research and 
development of new products, as well as plant control. 
This laboratory is in charge of an expert research chemist 
and the staff includes practical enamelers, engineers and 
ceramists. Vitro products are distributed not only in the 
United States and Canada, but also in South America. 
Europe, Australia and the Orient. 
The main office of the Vitro Manufacturing Company 
is at 928 Fulton Building, Pittsburgh, Pa. It is a Pennsyl- 
vania corporation, with a capital of $250,000. Josef Voll 
kommer is president, J. W. Wenning vice president, Theo- 
lore J. Vollkommer secretary, H. E. Roemhild. treasurer.
