Dummer joined his brother George Dummer's Jersey Glass Company on Washington Street between Essex Street and the Morris Canal in Paulus Hook (later became incorporated as Jersey City). He later obtained a patent for the manufacture of pressed glass by a process called "Dummer's scallop or coverplate." By the 1840s, the glass company was known as P.C. Dummer & Company and was selling glassware for home, decorative and commercial use. The company went out of business after the economic downturn following the Civil War.

Grant. He held the position until his death on September 14, 1875, in Jersey City, New Jersey.
