Unfortunately for Christensen, the M.F. Christensen and Son Company did not remain in business long. While Christensen's invention dramatically sped up and reduced the cost of glass marble production, a shortage of natural gas during the winter of 1916-1917 forced the company to cease operations in December 1917. The firm needed natural gas to heat the glass. The natural gas shortage caused the M.F. Christensen and Son Company to scale back production during the winter of 1916 and 1917, and the firm never regained financial stability.
