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 destroyed.
Undaunted by this misfortune, the owners immediately
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 enamels
for steel, cast iron and copper, coloring oxides, especially
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 decorating
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 manufactured
and controlled by chemical and ceramic methods. In
addition to a well equipped plant, this company has recently
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 Pennsylvania
corporation, with a capital of $250,000. Josef Voll
kommer is president, J. W. Wenning vice president, Theolore
J. Vollkommer secretary, H. E. Roemhild. treasurer.
