    • The present invention provides molded fireplace articles comprising a plurality of non-white inorganic fibers that are substantially uniformly coated with a colored metal oxide. The present invention further provides a method of manufacturing molded fireplace articles comprising: providing a plurality of non-white inorganic fibers; mixing the fibers with a binder and a liquid to form a slurry; pouring the slurry into a mold having a desired shape; and forming the slurry into a shaped article. A method of preparing non-white inorganic fibers is also provided, the method comprising the steps of: providing a colorant solution formed by dispersing or dissolving a metal compound into a carrier liquid, providing an inorganic fiber, applying the colorant solution to the inorganic fiber to form a colorant coated fiber, and heating the colorant coated fiber to a temperature sufficient to decompose the metal compound to a non-white metal oxide that is substantially uniformly coated on said fibers.
    • 本发明提供了包含多个基本均匀地涂覆着色金属氧化物的非白色无机纤维的模制壁炉制品。 本发明还提供一种制造模制壁炉用品的方法,包括:提供多种非白色无机纤维; 将纤维与粘合剂和液体混合以形成浆料; 将浆料倒入具有所需形状的模具中; 并将浆料形成成型制品。 还提供了制备非白色无机纤维的方法,该方法包括以下步骤:提供通过将金属化合物分散或溶解在载体液中形成的着色剂溶液,提供无机纤维,将着色剂溶液施加到无机纤维 以形成着色剂涂覆的纤维,并且将着色剂涂覆的纤维加热到足以将金属化合物分解成基本上均匀涂覆在所述纤维上的非白色金属氧化物的温度。
