Potts' double-pointed clothes iron became a standard household appliance widely used in the 20th century throughout North America and the European continent. Her patents of various styles of clothes irons were the most popular heavy metal irons ever made. The 1876 Philadelphia Exposition World's Fair displayed Potts's cold-handled sadiron. She lectured all throughout the United States promoting her cold-handled clothing iron mechanism. Her style of clothing irons became so popular that by 1891 special manufacturing machines were made that could mass produce thousands of semicircular wood handles in one day. Her innovative clothes iron was also a favorite item at the 1893 Chicago World's Fair. The Pott's iron mechanism was used worldwide through the 20th century where electricity was not available.
