  • Patent number: 5271888
    Abstract: The present invention relates to an improved process and partible mold for forming a light-weight synthetic ceramic log for use in natural gas, propane and wood-burning fireplaces and stoves which are both fully-vented and non-vented depending upon the particular design of the heat generating equipment. In the subject process, a flexible porous patterned screen is formed simulating the exterior bark portion of a tree or log having a reverse image. Such screen is designed with both porous and non-porous surface characteristics for mounting as a separate element within the partible mold. The flexible porous patterned screen is mounted within the partible mold having major interior surface areas which are capable of connection to a vacuum source for withdrawing water from a liquid composition containing ceramic fibers to rapidly form the ceramic log within the mold during short periods of vacuum molding.
