Abstract

A cloth heater and method for using the heater are provided. The heater utilizes a horizontally disposed surface, a heated glass panel, and support members. The horizontally disposed surface may comprise the top edge or surface of the heated glass panel, or a surface on a separate rack that is above and vertically inline with the top edge of the heated glass panel. The heated glass panel also has two opposing major surfaces. The support members physically support the heated glass panel and have electrical leads that communicate electrical power to the heated glass panel, thus heating the heated glass panel. When a cloth is placed across the horizontally disposed surface, the horizontally disposed surface supports the cloth, and the cloth makes contact with the two opposing major surfaces of the heated glass panel, thus heating the cloth at both opposing major surfaces.
