  • Publication number: 20210108084
    Abstract: A range of processes is described herein for the preparation of a range of ceramic glazes with traditional firing methods that represents significant efficiency and ecological advancements over existing methods and allows for the replacement of commercial ceramic colorant methods, while retaining the costly equipment and firing methods already used. The process allows for ceramic surface color while breaking standards for minimal amounts of transition metal colorant used. The nanoparticle-based glazes described here add new colors to the known ceramic surface palette and offers greater consumer safety as an alternative to existing coloring processes that use higher concentrations of toxic metal and an increased risk of metal leaching from the final ceramic vessel into its contents (e.g., soil, beverage, food).

  • Patent number: 10913856
    Abstract: A range of processes is described herein for the preparation of a range of gold nanoparticle (Au NP) ceramic glazes with traditional firing methods that represents significant efficiency and ecological advancements over existing methods and allows for the replacement of commercial ceramic colorant methods, while retaining the costly equipment and firing methods already used. The process allows for ceramic surface color while breaking standards for minimal amounts of transition metal colorant used. The nanoparticle-based glazes described here add new colors to the known ceramic surface palette and offers greater consumer safety as an alternative to existing coloring processes that use higher concentrations of toxic metal and an increased risk of metal leaching from the final ceramic vessel into its contents (e.g., soil, beverage, food).

  • Patent number: 5028053
    Abstract: A ball capable of providing an erratic, as well as a normal, bounce comprised of a hollow spherical member and, preferably, twenty-two integral hemispheric projections arranged in a predetermined pattern about the periphery of the spherical-shaped member. The projections are of uniform diameter which is a predetermined relationship to the diameter of the spherical-shaped member to achieve a desirable ergonomic effect. The cumulative volume of the hemispheric projections is substantially equal to one-half the volume of the spherical member and the radius of the spherical member is preferably of the order of 2.8 times the diameter of the projections. The game ball may be provided in the form of a kit including a cord having predetermined colored markers for creating the playing court which has a likeness of an international "PEACE" symbol. The projections may be provided with a similar "PEACE" symbol.
