Between 1868 and 1875, Bradley and Hubbard secured 33 patents relating to the design and mechanics of oil burning lamps (in all, the company would eventually patent a total of 238 designs and mechanical devices). The company was reorganized in 1875 as a joint stock company renamed The Bradley and Hubbard Manufacturing Company. Slag glass, a type of opaque, streaked, antique pressed glass that originated in England in the late 19th century, was used in glassware items such as lampshades, jugs, wine glasses and beakers.
