ABSTRACT:
A process for heating a hollow hair curler having walls constructed of a plastic material transparent to microwave and impermeable to water vapor and containing a mass of wicking material, such as an open cell form rubber, permeable to microwave energy including (1) dispersing a quantity of water into the wicking material through a filling hole at an end of the curler and (2) subjecting the curler to microwave energy in a conventional microwave oven to heat the water dispersed in the wicking material and thereby heat the curler. The filling hole is left open to provide a vent allowing escape of steam to insure that excessive pressures are not generated within the curler during the heating process.
