In 1892, management decided to expand the factory's capacity by adding a second tank. The new tank would add approximately 50 pots of capacity. In early April, construction of the facilities for the new tank began. "Modern and improved methods in all departments of the works" were used, improving the efficiency in manufacturing and shipping. The new buildings were made fire-resistant by using stone, brick, and iron for construction materials. They were also well ventilated, which made the work environment more comfortable for the glass workers. The expansion increased total capacity to about 90 pots. This made the works the second-largest glass factory in the United States. Expenditures necessary to finance the expansion were $100,000 (over $2.5 million in 2012 dollars).
