Abstract:
The method of molding a three-dimensional synthetic ceramic fiber log having areas of enhanced thermal surface treatment that can be used in gas fired fireplaces, the process comprises the steps ofa. fitting a mold screen within a support mold, said support mold having a base portion and a top portion with a mold cavity therebetween,b. depositing a thermal texturing paste over portions of said mold screen,c. closing said support mold and introducing a ceramic fiber slurry under pressure within said mold cavity,d. coalescing said ceramic fibers on the mold screen and thermal texturing paste portions within said support mold by injection of air pressure,e. express drying said coalesced fibers by forcing excess liquid out of the mold cavity by air pressure,f. capturing and recovering said excess liquid from said mold within a retainment enclosure,g. removing said coalesce fibers in the form of an artificial fireplace log from said mold and drying said ceramic log at an elevated temperature during a second drying step.
