Abstract
A mineral fiber mat is formed from a slurry of a known fiber material and a binder in a vacuum mold. The mold includes a porous screen through which a vacuum is drawn to remove water from the slurry while leaving the mat on top of the screen. A cover is pressed down on the mat under the vacuum. The fiber mat or layer is formed to include a simulated surface, such as tree bark, or a brick wall. To form a hollow log the uncured layer is placed over a core to provide a partial enclosure around the core that is of a sufficient size to permit a gas burner to be placed in the enclosure and hidden from view. Panels that are to be used flat are cured while held flat.
