Hartford City Glass Company was among the top three window glass manufacturers in the United States between 1890 and 1899, and continued to be one of the nation's largest after its acquisition. It was also the country's largest manufacturer of chipped glass; with capacity double that of its nearest competitor. The company's works was the first of eight glass plants that existed in Hartford City, Indiana during the Indiana Gas Boom. It became the city's largest manufacturer and employer, peaking with 600 employees.
Many of the skilled workers employed at the Hartford City Glass Company were from Belgium, at the time the world’s leading manufacturer of window glass. The Belgian workers and their families accounted for over one third of Hartford City's population during the 1890s, and lived on the city's south side. Because of the importance of the French-speaking Belgians, one of the local newspapers featured articles in French.
In 1899, Hartford City Glass was acquired by the American Window Glass Company, which controlled 85 percent of the American window glass manufacturing capacity. During the next decade, the company began replacing its skilled and well–paid Belgian glass blowers with machines and less-skilled machine operators. The company used the Hartford City plant to test and refine the new technology. Most of the Belgian glass workers left town.
During the 1920s, competitors developed new window glass production processes that eclipsed the American Window Glass technology, and the company lost its advantage. By the time the Great Depression struck, the Hartford City plant had closed.
Manufacturers drawn to Indiana 
During the late 1880s, the discovery of natural gas in Eaton, Indiana started an economic boom period in East Central Indiana. Manufacturers were lured to the region to take advantage of the low cost fuel. Blackford County, a small rural county located close to Eaton, had only 181 people working in manufacturing in 1880. By 1901, the county had over 1,100 people employed at manufacturing plants in small communities such as Hartford City, Indiana. Between 1880 and 1900, populations doubled in area counties such as Blackford, Delaware, and Grant. The region became Indiana’s major manufacturing center.
Hartford City 
Like many Indiana communities during the gas boom, Hartford City’s leaders sought to take advantage of their newfound energy resource. The Hartford City Land Company was formed in 1891 as part of the effort to attract manufacturers. The company offered "free sites, free gas, excellent switching facilities, and reasonable cash subsidies" as enticements for manufacturers to locate in the boom town. Manufacturers that used high quantities of energy were especially attracted to no-cost or low-cost natural gas sites, and glassmaking was one of those energy-consuming industries.
Hartford City's success in attracting manufacturers can be indirectly measured by its population growth. The city's population was 2,287 in 1890, but grew to 5,912 by 1900. In 1890, the city convinced glassmaker Richard Heagany to relocate from Kokomo, Indiana. An additional glass maker, Sneath Glass Company, relocated from Tiffin, Ohio, in 1894. During 1901, Indiana state inspectors visited 15 manufacturing facilities in Hartford City. These manufacturers employed 1,077 people, and the American Window Glass plant (the former Hartford City Glass Company) plus the Sneath Glass works accounted for over half of the manufacturing employees. By 1902, Hartford City was the home of 8 glass factories.[Note 1]
Organization and management 
In 1878, Glassmaker Richard Heagany organized a window glass plant in New York and was the factory's superintendent. That plant became the largest window glass plant in the state. In 1886, he moved to Kokomo, Indiana and opened the first window glass plant in the region to use natural gas as a fuel source. Heagany's Kokomo plant lasted three years before it was destroyed by fire. Instead of rebuilding in Kokomo, he moved to Hartford City and organized the Hartford City Glass Company. The company was organized in 1890 with the financial assistance of several capitalists. Production began in early 1891 after the plant was constructed. Heagany was the plant manager until his retirement in 1899.
One of the principal stockholders of the new company was multi-millionaire A. M. Barber. Barber was involved in grain and banking in Akron, Ohio. Another important investor from Akron was Colonel Arthur Latham Conger, who was the company's first president. Conger was a Civil War veteran who invested in companies in Ohio and Indiana (including in Kokomo). He was also elected president of the Hartford City Land Company in 1893. Hartford City's Sydney W. Cantwell was secretary of the Hartford City Glass Company during its early years. He was also president of the state organization of window glass manufacturers. Cantwell was an attorney involved with the Blackford County Bank, Akron Oil Company, and Hartford City Land Company. Another Hartford City investor, Henry "H. B." Smith, was president of Hartford City's Citizen's Bank.
Management change 
Top management changed during 1895 after the company's annual shareholder's meeting. Colonel A. L. Conger, who had been president since the company's beginning, lost his position to another colonel from Akron, George T. Perkins. Conger had fallen into disfavor with many of the local citizens. He immediately expressed his unhappiness with the election by selling his company stock and leaving town. Conger's stock was purchased by Kokomo banker John A. Jay. Officers of Hartford City Glass in 1896 were: George T. Perkins, President; John A. Jay, Vice President; H.B. Smith, Treasurer; Richard Heagany, General Manager; and John Rodgers Johnston, Secretary.
Colonel George Tod Perkins was a Civil War veteran and president of the B. F. Goodrich Company. He was also involved in banking, and had been president of the Bank of Akron. John R. Johnston began working at the Hartford City plant in 1890 as a bookkeeper. He was elected secretary after 4 years. Johnston lived in Hartford City and helped Heagany run the business. Heagany submitted his resignation at the August 1899 board meeting, retiring after 42 years in the glass business. Johnston became plant manager at that time. Johnston resigned a short time later, effective April 1900. He formed Hartford City's Johnston Glass Company in September of the same year.
The Hartford City Glass works was located on Hartford City's south side, and originally occupied 12 acres (4.9 ha). To help meet the housing needs for the new factory's employees, 184 houses were built nearby. During its peak years, the company employed 500 to 600 people. In 1896, 443 workers at the plant lived in Hartford City, especially on the south side. Assuming each local worker had a family of five, over one third of the city's population (2,235 of "an estimated 6,000") was financially dependent upon Hartford City Glass.
The window glass manufacturing process used by Hartford City Glass was known as the Cylinder Method. The process was labor intensive, and required the services of a glass-blower and glass–cutter—who were both highly skilled and well paid. The glass–blower led a small production crew that included skilled and unskilled workers. Their workstation was adjacent to a ceramic pot located inside the furnace. Each pot contained molten glass created by melting a batch of ingredients that included sand, soda, and lime. In the first step of the process, molten glass was extracted from the pot. The glass–blower and his helper used a blowpipe, which was typically 4 feet (1.2 m) to 5 feet (1.5 m) long, to create a bubble of molten glass. The glass–blower manipulated the bubble into a cylinder, and removed it from the pot. (Tanks, which were essentially huge brick pots with multiple workstations, eventually replaced pots.) The cylinders were 12 inches (30.5 cm) to 16 inches (40.6 cm) in diameter, and 4 feet (1.2 m) or 5 feet (1.5 m) long. Next, the glass–cutter cut the cylinder, and the glass was flattened. It was necessary to gradually cool the glass, a process known as annealing, to prevent it from breaking. A lehr was used to anneal the product. A typical 20th century lehr was a large conveyer inside a long oven. The newly–made glass gradually moved from the hot end of the lehr to its opposite end, which was at room temperature. The glass would then be cut into the desired window glass size, placed in a box, and moved to inventory. It is not known if (or when) the lehrs at the Hartford City plant had conveyors.[Note 2]
The Belgians 
During the late 19th century, glass–blowers were difficult to find. Belgium was the largest exporter of window glass to the United States, and plant manager Heagany previously used the skills of glass-blowers from that country in his Kokomo glass works. In Hartford City, Heagany again relied upon Belgian workers for the skilled positions in his glass works.
The city's influx of French-speaking Belgians had an impact on the town. The south side (south of Lick Creek) became known as Belgium Town. Most Belgians were Catholic and they built the city's Catholic church near their homes on the city's south side. The church's Father Dhe was a native of France and was also involved with glass making. During the early 1900s, the local Blackford County Gazette claimed to be the "only newspaper in State that prints French and circulates among the window glass and iron workers, the highest paid skilled mechanics in the world."
The Belgian workforce also had an impact on the city's north side. Hartford City's Presbyterian Church, which is now part of the National Register of Historical Places, was built one block north of the courthouse in 1894—and features large stained glass windows imported from Belgium. For over 50 years, the bigger of two huge windows was considered the largest single-frame window in the state of Indiana. These stained-glass windows, plus at least four smaller ones, were installed by the local (and mostly Catholic) Belgian glass workers.
Construction of Hartford City's new glass works was completed in early January 1891, and production started shortly thereafter. Natural gas was the plant's original fuel source for both the furnace used to make the glass and the lehr used to gradually cool it. With a capacity of 30 pots, the plant was "said to be the largest and best arranged window glass works in the world." The Hartford City plant had more than double the capacity of some of the window glass plants built a few years earlier in Ohio.[Note 3] During the next forty years, the plant was always one of the three largest window glass works in the United States, usually second or third.
Initial production at the Hartford City plant continued until June, when the works was shut down to decrease inventories. Summer shutdowns were normal in the glass industry at that time. The heat from the furnaces combined with summer weather made extremely uncomfortable working conditions, justifying the summer months as the best time to shut down for maintenance (or for manipulation of inventories). In the case of the first year's shutdown for the Hartford City Glass works, production was restarted in October.
The plant's capacity was increased twice in the next two years.[Note 4] In 1892, management decided to expand the factory's capacity by 50 pots. The expansion enlarged capacity to 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). Capacity was increased again in 1893. This time, a tank with the capacity equivalent to 60 pots was added.[Note 5] This expansion cost $150,000 (over $3.8 million in 2012 dollars), and was said to "give employment to 350 men." By September, the plant had a payroll of $45,000 (over $1.1 million in 2012 dollars) per month, and employed 500 glass workers.
Management shut the plant down during July and August 1985 for its summer break. By that time, the glass works was using two tanks, which were equal to 100 pots in capacity. By 1896, the plant employed 550 people, and produced about 2 million square feet of window glass per month. In addition to window glass, the company was the nation’s largest producer of chipped glass, with capacity double that of the second largest manufacturer. Chipped glass was a popular ornamental glass used for interiors of office buildings and with furniture. At that time, the plant was the second-largest window glass producer in the country, although it became the third largest later in the year. Its grounds covered 25 acres (10.1 ha), and had its own railroad spur off of the Pennsylvania Railroad. The grounds contained two melting rooms, two warehouses, a blacksmith shop, and a machine shop. The tank in one of the melting rooms was 18 feet (5.5 m) long, 18 feet (5.5 m) wide, and 6 feet (1.8 m) deep. One tank required 4 flattening ovens and a cutting room.
Plans for the addition of another tank began in late 1896. A third tank would make the Hartford City plant the largest in the country. As part of the conditions for expansion, the plant owners requested housing for its potential new workers. Although the houses were built, the company was not satisfied, as the expansion was never consummated.[Note 6] Without the third tank, the workforce still grew to 600 by 1898.
In 1898, a group of men led by James A. Chambers organized a glass trust called American Window Glass Company. The company was formed from the American Glass Company, but did not incorporate until 1899. The trust planned to acquire 70 glass plants, "some of which it will close to bring the production down to the demand." The prices offered for the glass plants were very generous. Owners of the glass plants could sell their plant for either cash or a combination of cash and stock in the new company. Many owners chose to receive stock.
The trust was incorporated effective August 2, 1899. James A. Chambers continued as president, and Hartford City’s H.B. Smith was one of the directors of the newly incorporated company. Initial acquisitions included over 20 major window glass plants, including Hartford City Glass Company. Most of the original acquisitions were from Indiana and Pennsylvania. Those glass plants were important enough to enable American Window Glass to control 85 percent of the window glass production in the United States.
Many of the Indiana glass works acquired by the trust were from the East Central Indiana Gas Belt. Among those plants were the Hartford City Glass Company; and the nearby Muncie plants of Maring, Hart, and Company and C. H. Over. Other plants were located in Anderson, Dunkirk, and Fairmount, Indiana. The Hartford City Glass Company became known as Plant Number 3 of the American Window Glass Company. J. R. Johnston, already manager for Hartford City Glass Company, was named manager of the American Window Glass version of the same plant in December. A second window glass factory from Hartford City, Jones Glass Company, was also acquired—and became plant No. 32. Eventually, the company acquired 41 glass factories.
American Window Glass 
After the acquisition, the Hartford City Glass works became known as plant number 3 of the American Window Glass Company. The plant employed 450 people in 1901. As natural gas supplies in Indiana became depleted, many manufacturers moved or did not survive. The major plants of the American Window Glass successfully changed energy sources from natural gas to gas made from coal. The company also had a technological advantage. Instead of using a glass–blower, American Window Glass plants extracted molten glass with a machine. The machine, which was not immediately utilized at all American Window Glass plants, was known as the Lubbers blowing machine. Refinements to the machine and glass making process were made at the Hartford City works by plant manager Harry G. Slingluff. Production records for the entire company were set at the Hartford City plant in 1905 and 1907—using the Lubbers machines.
Lubbers machine 
The glass blowing machine used by American Window Glass factories was created by Pittsburgh resident John H. Lubbers, and he continued to contribute improvements to the machine over the next decade. By using the Lubbers machine, human glass blowers were replaced with a machine operator paid 30 percent of the glass blower wage. The machine was also five times more productive than the human blowers. It could make windows four times as large because a larger cylinder was extracted from the tank of molten glass. Thus, the highest–paid skilled workers in the United States were considered obsolete. In the case of Hartford City, machines replaced most of the human glass blowers by 1908.
During the spring of 1900, rumors circulated that American Window Glass planned to move production from smaller plants in nearby Dunkirk and Redkey (factories 17, 30, 34, and 41) to the large southside Hartford City plant. If the Hartford City plant would have its capacity expanded equal to the capacity of the plants to be consolidated, then Hartford City "will become the greatest window glass town in the world." The plant would employ nearly 1000 people, equaling the largest window glass plant in the world in capacity. That plant in combination with Hartford City's two other window glass factories, not even considering the flint glass plants or bottle plants, would make the city's window glass capacity the highest in the world. The rumor had some truth—smaller plants were eventually closed. However, Hartford City's large southside plant was not expanded.
In 1905 American Window Glass sold some of its smaller plants, including Hartford City's plant number 32. Plant number 3 still continued operations. It employed 500 people in 1910. Before the start of World War I, American Window Glass Company was still the dominant window glass manufacturer, accounting for over half of the nation's window glass manufacturing capacity. In 1913, the company continued to close many of its smaller plants, while the large plants were equipped with the glass blowing machines. Plant number 3 was the third largest window glass factory in the United States, and the largest west of Pennsylvania. The Belgian portion of Hartford City's glassmaking workforce was dramatically reduced because of two factors: the glass blowing machine replaced human glass blowers; and Belgians had difficulty returning from summer vacations in their European homeland after the start of World War I.
American Window Glass made record profits in 1920. All of the company's small plants had been sold or closed by that time. The glass-blowing machines were still being used to extract molten glass. The company was described as having "six large and well-equipped plants located near the Pittsburgh district, and one large plant at Hartford City, Ind."
During the beginning of the 20th century, competitors of the American Window Glass trust used a different approach to gain a technological adavantage. The machines used by American Window Glass replaced glass blowers, but still used the same blowing and cutting process used in the 1880s—although the company was constantly working to make the process more efficient. Competitors such as American inventor Irving W. Colburn began working on a machine that produced window glass using a different process. Colburn patented his work during the first decade of the 20th century. Although he filed for bankruptcy in 1912, his patents were purchased by Edward Drummond Libbey and Michael J. Owens—who hired Colburn to continue work on the machine. Owens was the creator of the Owens Bottling Machine that revolutionized the glass bottle industry. Working with Colburn, Owens improved the window glass machine enough that it began being used for production in 1921. By 1926, Libbey-Owens had gained a window glass market share of 29 percent, while American Window Glass's share was 59 percent. During the 1920s, Pittsburgh Plate Glass also developed a new process for making window glass, creating even more competition in the window glass industry.[Note 7]
Because of the improved technology and processes utilized by competitors, many of the American Window Glass patents, and much of its machinery, became obsolete. By the late 1920s, American Window Glass was forced to begin re-equipping its plants with new machinery. The company underwent a financial reorganization in 1929. Dividends on its preferred stock were lowered. Although a few plants were re-equipped, the Hartford City plant was not. Hartford City's natural gas supply was depleted, and the type of sand used to produce glass was in better supply near other American Window Glass plants in Pennsylvania. Thus, American Window Glass Company plant number 3, the former Hartford City Glass Company, was closed in 1929.
Notes and references 
- A 1902 Hartford City directory lists 7 glass factories in Hartford City: American Window Glass Company factory number 3, American Window Glass Company factory number 32, Blackford Glass Company, Clelland Glass Company, Diamond Flint Glass Company, Johnston Glass Company, Hartford City Flint Glass Company, and Sneath Glass Company. An eighth plant, the Sans-Pariel Bottle Company, is listed in a 1901 state inspection report. The count of eight factories excludes predecessor companies. The Hurrle Glass Company factory, also listed in the 1901 report, became the Clelland Glass Company. Hartford City Glass Company and Jones Glass Company, both listed in a state inspection report for 1898, became American Window Glass Company factories 3 and 32, respectively.
- For more detail on 1880s glassmaking, see Appendix A in Jack Paquette's Blowpipes book. Paquette, a former Vice President of Owens-Illinois Glass Company, has written at least 3 glass–related books. Window glassmaking at the Hartford City Glass Company plant is discussed, by a former glassworker who's father worked at the Hartford City plant, in a book produced by the Blackford County Historical Society.
- The first window glass plant built in Fostoria, Ohio, (Mambourg Glass Company built in 1887) had a capacity of 13 pots. In Toledo, Ohio, the Toledo Window Glass Company plant was built with a 10 pot capacity in 1888.
- Capacity "expansion" was difficult to measure precisely, as tanks sometimes replaced pot furnaces instead of solely adding to capacity. A tank is essentially a giant pot, which was made of brick instead of ceramics. The pot-equivalency of a tank varied, depending on the tank size and way the tank was equipped.
- At that time, two types of furnaces were used to create the molten glass. The older type was a pot furnace, where ceramic pots were heated inside the furnace to melt the batch of ingredients needed to make the molten glass. The newer type of furnace used a large brick tank that could be operated continuously or by the batch.
- Testimony before the United States House Committee on Ways and Means in 1913 listed the Hartford City Glass Company as having two tanks in 1898—not three. In 1913, when the plant was owned by American Window Glass Company, it was still described as having two tanks: a large tank "equipped with 10 machines" and a "smaller tank, with a six-machine equipment".
- In Europe, Belgian Emil Fourcault developed his own mechanized method (Fourcault process) to produce window glass. His process was adopted during the 1930s by a group of companies in the United States called Furco Glass. Market share for American Window Glass fell to 20 percent in the United States. The remainder of the market was dominated by three other manufacturers: Libbey-Owens with 30 percent, Pittsburgh Plate Glass with 25 percent, and Furco with 25 percent.
