  • Ink jet printer ink for printing on ceramics or glass
    Patent number: 5407474
    Abstract: A pigmented ink usable in an ink jet printer in which the maximum particle size of the pigment is sufficiently small not to block the nozzles or the filters of the printer and the particle size range is sufficiently narrow for the ink to have a low viscosity for the printer to operate. The ink is particularly suited for printing on ceramics or glass.

  • Method of protecting pigments with transparent crystalline zircon
    Patent number: 4482390
    Abstract: Pigments which are unstable at high temperatures are protected by inclusion in zirconium silicate crystals. Improved protected pigments are produced by the step of precipitating the constituents of the protected pigments from aqueous or non-aqueous solution. Especially applicable to pigments for ceramics such as those containing cadmium and pigments for use in plastics where contamination of foodstuffs is to be avoided.
