Hemingray moved its factory from Cincinnati to Covington

CINCINNATI GLASS WORKS.

Of the many kinds of glass in common use, there is but one description made in Cincinnati; and the manufacture of this is limited to one factory, that of Gray & Hemingray, of Hammond street.

Flint glass, the best kind used for decanters, tumblers, pitchers, and the finer kinds of bottles, have been manufactured by Messrs. Gray & Hemingray, at their factory in Hammond street, for a period of more than five years. Their operations in the beginning did not much exceed a hundred dollars a week; it has now increased twelve fold.

In the month of April, 1852, they removed their furnaces to Covington, where they are in full operation, on the bank of the Ohio, between Madison and Washington streets.

The manufactory employs forty-five hands in the various branches; turn out between twelve and fourteen; hundred dollars worth of work in the week; and consumes in the operation about three hundred bushels of coal.

There is no cessation of work in a glass-house. Night or day, meal time or sleeping time, the fires never cease to burn, the glass to melt, or the workmen to ply their skill. From the time the furnaces are heated, until some necessity for repairs imperatively demands a pause, the whole machinery, animate as well as inanimate, continues in active motion for years. Some glass works have frequently been in unceasing operation for five years; and there is one house in Pittsburgh whose furnaces have never been been extinguished for eight years and nine months.

The quantity of glass now manufactured in Great Britain does not amount to less than $10,000,000 annually. The number of men employed in the various departments of manufacture exceeds 40,000. The manufacture of glass in the United States is carried on in all the Eastern cities to some extent. Boston, however, manufactures the largest quantity. In the West, Pittsburgh is the great centre of glass manufacture.

The cheapness of coal more than any facilities it enjoys for procuring the ingredients requisite for this purpose, makes Pittsburgh an elligible [sic] eligible point for the manufacture of glass. The lead and pearl ashes used there, are both procured in Ohio; but the low price of coal, the consumption of which is a heavy item of expenditure, gives her an advantage over Cincinnati and other cities, more distant from the coal region. This obstacle to a fair competition, it is to be hoped, will soon be partially removed by the opening of railroads into the heart of the coal country. The larger portion of the glass made in Cincinnati is used by our own wholesale merchants; still some of it is expected to other points, east as well as south.
