  • Patent number: 4901706
    Abstract: An ash mat comprises a laminate preformed to the size and shape of the bottom of a structure in which ashes are generated, such as a fireplace, a wood burning stove or an outdoor bar-b-que appliance. The laminate is made up of two outer layers of aluminum foil and an inner layer of fiberglass matting or spun glass matting adhered to the outer layers. The laminate is provided with handles so that it can be picked up easily, thus facilitating disposal of the mat and its contents. The handles are in the form of holes through the laminate and are preferably reinforced to prevent tearing of the material and to avoid sharp edges which would be hazardous to the user.
