Abstract
Ceramic colours containing effect pigments and a liquid glass forming component for decoration of metallic, ceramic and glassy articles and a process for the preparation of a ceramic glaze.
Claims22
A process for preparing a glazed article comprising:
- (a) printing or coating a ceramic colour on a ceramic or metallic body,
- (b) drying the ceramic or metallic body obtained in step (a),
- (c) firing the ceramic body obtained in step (b) at a temperature ≥1,000° C. or the metallic body obtained in step (b) at a temperature in the range of 450° C.-950° C.,
- wherein the ceramic colour comprises at least one liquid glass forming component that is a liquid polymer selected from polysilsesquioxanes and at least one effect pigment based on flake-form substrates, and optionally a solvent, optionally a binder, optionally an absorptive ceramic pigment and optionally at least one additive.
