[30][31], During World War I, Bakelite was used widely, particularly in electrical systems. [5][6] It was the first synthetic thermosetting plastic produced, and Baekeland speculated on "the thousand and one ... articles" it could be used to make.

However, the high temperatures required to create this tends to cause violent foaming of the mixture when done at standard atmospheric pressure, which results in the cooled material being porous and breakable. [10], Baekeland started semi-commercial production of his new material in his home laboratory, marketing it as a material for electrical insulators. Gradually wall sockets were developed to supplement those that screwed into lampholders.[9][10][11]. As electricity became a common method of operating labour-saving appliances, a safe means of connection to the electric system other than using a light socket was needed. Most sockets with this rating are of the "T-slot" type. Recommended for intricate high strength parts. [9] He announced his invention at a meeting of the American Chemical Society on February 5, 1909. The creation of a synthetic plastic was revolutionary for its electrical nonconductivity and heat-resistant properties in electrical insulators, radio and telephone casings and such diverse products as kitchenware, jewelry, pipe stems, children's toys, and firearms. As ways were found to manufacture Bakelite in bright colors, it began to be used for all sorts of decorative objects, especially jewelry.
