  • Patent number: 4142383
    Abstract: A method for the production of decorative objects by providing a viscous liquid and a particulate metal and/or mineral through an opening in a hollow transparent glass envelope and then bonding a cap over the opening with a resin impervious to said liquid is described. The refractive index of the viscous liquid and glass are approximately equal visually. The viscous liquid is preferably glycerine admixed with clear miscible solvents which reduce the viscosity depending upon the metal or mineral used. The liquid is provided through the opening in the hollow glass envelope without wetting the sides of the opening in a manner which leaves a gas (air) pocket inside the envelope adjacent the opening and above the liquid and then a cap is bonded over the opening adjacent the gas pocket. The decorative object is preferably in the form of jewelry, such as earrings or pendants.
