As one manufactory dies out only to give place to another, so the present New England Glass Company was formed, and became the purchasers of the Porcelain Works. That company, from 1817, to the present time, have pursued the business with signal success; beginning with the small capital of forty thousand dollars, they have from time to time increased it, until it amounts at the present time to half a million of dollars. They commenced business with a small six-pot furnace, holding seven hundred pounds to each pot; employed, all told, about forty hands, and the yearly product did not exceed forty thousand dollars. They now run five furnaces, averaging ten pots to each, capacity of two thousand pounds to each pot. They employ over five hundred men and boys, and the yearly product is not less than five hundred thousand dollars. In 1820 some of their workmen left them, built a factory in New York City, and conducted their business under the firm of Fisher & Gillerland. In 1823 Gillerland dissolved the connection and built, on his own account, a manufactory in Brooklyn, N.Y., which he conducts at this period with great skill and success, and is considered the best metal mixer in the United States. In 1825 a Flint-Glass Manufactory was established by individual enterprise in Sandwich, Mass. Ground was broke in April, dwellings for the workmen built, and manufactory completed; and on the 4th day of July, 1825, they commenced blowing glass--three months from first breaking ground. In the following year it was purchased of the proprietor, a company formed, and incorporated under the title of Boston and Sandwich Glass Company. Like their predecessors, they commenced in a small way; beginning with an eight-pot furnace, each holding eight hundred pounds. The weekly melts at that period did not exceed seven thousand pounds, and yearly product seventy-five thousand dollars; giving employment to from sixty to seventy hands. From time to time, as their business warranted, they increased their capital until it reached the present sum of four hundred thousand dollars. Their weekly melts have increased from seven thousand pounds to much over one hundred thousand pounds; their hands employed from seventy to over five hundred; their one furnace of eight pots to four furnaces of ten pots; and yearly product from seventy-five thousand dollars to six hundred thousand dollars.
