Abstract
A novel fireplace element is made by a novel process wherein the fireplace element is first molded from a mixture of refractory and ceramic fibers and removed from the mold in a green state. While the fireplace element can be treated in the green state, it is preferred that the fireplace element is cured to provide a rigid fireplace element of the type used in artificial fireplace log sets. The element if not already processed is provided with a surface of loosened fibers so that the loose fibers will reach an incandescent glow set state and give the appearance of the total element being incandescent well before the surface and/or body of the fireplace element can reach an incandescent temperature.
