    摘要: New methods of forming color-coated gemstones are provided. These methods broadly comprise subjecting a source of metal (e.g., an organometallic compound) to a vapor deposition process so as to form the metal source into a vapor that is subsequently deposited onto the surface of a previously heated gemstone. The vapor is also diffused into the gemstone so as to form a mixed zone of gemstone having the metal source dispersed or intermixed therein. The coated gemstone is then subjected to heat treatment to alter the valence state of the metal in the coating until the desired colored coating is obtained, resulting in coatings having superior adhesion and optical properties.

    摘要: Embodiments provide methods for the protection and consolidation of calcareous materials. An exemplary method includes providing an aqueous solution of a hydroxycarboxylic acid, adjusting the pH of the aqueous solution by adding an alkaline agent, and applying the pH-adjusted aqueous solution to a calcareous mineral to form a conversion layer on the mineral. The calcareous mineral may, for example, be carbonate rock, particularly limestone and marble, or may be part of masonry material, aggregates, or fillers. Adherent conversion layers are readily formed at ambient temperatures and, therefore, methods provided are suitable for field application. Conversion layers so formed are provided as further embodiments.

    摘要: An aqueous ruthenium chloride solution for blackening ceramic surfaces includes ruthenium chloride; water present in an amount effective to provide an aqueous solution of ruthenium chloride; and a buffer which is selected from the group consisting of sodium acetate, sodium propionate, potassium acetate, potassium propionate, and mixtures thereof, and which is present in an amount effective to provide the aqueous solution with a pH of at least 1.5. A method for dyeing a ceramic surface includes applying the aqueous solution of ruthenium chloride to a ceramic surface by at least one of spraying, dipping, painting and printing to provide a treated surface; drying and firing the treated surface at a temperature ranging from about 300 to about 1400.degree. C. for a period of time ranging from one half hour to five hours; and grinding and polishing the treated surface to even out the treated surface.
