ABSTRACT:
A method of making a sponge device is provided. This method includes introducing a curable liquid sponge forming material into a form, placing a handle into the material before it is fully cured, heating the form to cure the material, removing the cured material from the form, and rinsing the cured material. Another aspect of the present invention is the assembly for making this sponge device. This assembly includes a runner for joining a plurality of handles, plates that are spring-biased together to support the handles, a chase formed of heat conductive metal having a shelf where the plates can be set, and a silicone form having a plurality of cavities therein for receiving the sponge forming material.
