  • Patent number: 9434879
    Abstract: Liquid compositions for etching glass are disclosed herein. The liquid composition may include a non-active etching agent precursor that is inactive with respect to chemically etching glass in an amount of at least 2.5% by weight of the total composition, a binder and a liquid vehicle. The precursor may include an alkali metal salt having an activation temperature of at least 400° C. and when heated to above the activation temperature, the precursor yields an active etching agent suitable for chemical etching of glass.
    Type: Grant

  • Patent number: 9340448
    Abstract: A method of producing a substrate having a frosted appearance, an article having a frosted appearance and frost-imparting compositions are disclosed. The method includes applying a frost-imparting composition onto a ceramic substrate and firing the coated substrate above 400° C. to impart the frost appearance. The frost-imparting composition comprises a liquid vehicle, 20% to 90% by weight of glass frit particles and less than 10% by weight of at least one gas-releasing material, inactive below an activation temperature of at least 400° C. The gas releasing material may include carbonate, nitrate, iodate, bromate, chlorate, fluoride, manganate, dimanganate and sulfate compounds. The firing temperature is chosen to be above the activation temperature of the gas-releasing material, above which the gas-releasing material yields gas bubbles and above a temperature that causes the glass frit particles to behave as a viscous liquid.

  • Patent number: 7296884
    Abstract: An inkjet ink capable of undergoing polymerization (curing) after exposure to microwave radiation, and method for printing and fixation the above ink on various substrates by ink jet printer and microwave source is disclosed. Ink compositions suitable for microwave curing are provided. These inks overcome the problems associated with drying of solvent and water based inks, and curing of UV inks. The present invention provides also a method for quick fixation of inks in which the ink vehicle is composed of molecules having appropriate dielectric properties.
