  • Patent number: 9017595
    Abstract: Cellular ceramic materials, for example closed cell glass ceramic materials, for use in construction of buildings comprising a clay material, carbon, and water used to form the cellular ceramic blocks, slabs and beams by expansion of the particles inside the ware. The cellular ceramic materials are produced by first mixing the clay, carbon and about 40% to about 70% water by weight of the clay in the mixture, allowing the mixture to cure, drying the cured mixture, then firing the dried mixture at a temperature and for a period of time sufficient to melt the surface of the mixture. The clay material can be, for example, surface clays, ball clays, kaolin, shale, fly ash and/or bentonite. In another embodiment a mixture of volcanic ash, carbon and water can be formed and layered with the mixture of clay, carbon and water.

  • Patent number: 6309491
    Abstract: A pottery article decorated with a selected rock, such as a lava rock, is prepared by shaping a pottery article, such as a vase, from pottery clay, then partially drying the vase and forming a hole in the side of the vase, large enough to force the rock into so that it will be held in place by the surrounding pottery clay. The edges of the hole are cut to a sharp angle. A multiplicity of smaller holes are formed in the pottery clay in the region around the rock to inhibit the cracking of the pottery from cracking due to shrinkage during subsequent drying and firing. The pottery is then dried at room temperatures for about two weeks. Optionally, the holes may be filled with a moist clay/glaze mixture and dried again. The article is then fired at a cone 08 for about twelve hours and cooled, then glazed by dipping in a glaze bath and firing again at a cone 05 for about six hours.

  • Patent number: 6264881
    Abstract: A process for the production of faujasite X agglomerates containing at least 95% of faujasite LSX, that is to say with an Si/Al ratio equal to 1, constituting the active adsorbent. The agglomerate is formed from zeolite LSX and from a binder which can be converted to zeolite, the conversion of which to active zeolite is obtained by conversion to zeolite in a sodium hydroxide/potassium hydroxide or sodium hydroxide liquor.

  • Patent number: 6216896
    Abstract: A fossil molding fabrication method includes the steps of (1) preparing a fossil skeleton material; (2) mixing the fossil skeleton material with water to form a paste-like fossil skeleton material, then filling the paste-like fossil skeleton material in the cavity of a flexible mold; (3) preparing a base rock material, then mixing the base rock material with water to form a paste-like base rock material, and then covering the paste-like base rock material over the fossil skeleton in the flexible mold; and (4) keeping the paste-like base rock material away from the radiation of the sun and letting it be dried in the air, and then removing the molding thus formed from the mold, so as to obtain a fossil molding. A cover rock may be covered on the base rock over the fossil skeleton.
