ABSTRACT:
A process for making a mineral fiber artificial log that can be used in vented and unvented gas fireplaces, fireplace inserts, and free-standing gas fire room heater to simulate the appearance of a real burning log. The process utilizes a screen mold formed from a pattern that can be made to give the desired exterior configuration and size for the formed log. The screen mold is placed in an outer porous jacket and then in a vacuum chamber. A slurry of the formulation containing mineral wool fibers, a suitable high temperature binder, and water is drawn into the mold while contained in the vacuum chamber, so liquid is drawn through the mold and mineral fibers are trapped in the mold. The log is formed to the size and shape of the mold. Once molded, the log is removed from the mold, dried in an oven, treated with a suitable rigidizing exterior coating, and again oven dried. The log is painted suitably, dried again, and packaged for sale.
