Abstract
A glass or glass ceramic element for household and/or heating appliances is provided. The element includes a transparent glass or glass ceramic substrate and a coating. The substrate has a main surface. The coating is on at least a portion of the main surface. The coating is a glass-based coating that includes a pigment and a filler. The pigment includes an IR-reflecting material and the filler has a specific molar heat capacity of not more than 5 mJ/(mol·K).
Claims21
A glass or glass ceramic element for household and/or heating appliances, comprising:
- a transparent glass or glass ceramic substrate that has a main surface;
- and
- a coating disposed on at least a portion of the main surface,
- wherein the coating is a glass-based coating that comprises a pigment and a filler, wherein the pigment comprises an IR-reflecting material, and wherein the filler has a specific molar heat capacity of not more than 5 mJ/(mol·K).
A paste, comprising:
- a binder precursor phase, the binder precursor phase comprising a material selected from a group consisting of:
- a glassy material, a glass flux, a glass frit forming material;
- a pigment comprising an IR-reflecting material;
- and
- a filler having a specific molar heat capacity of not more than 5 mJ/(mol·K).
A method for producing a glass or glass ceramic element for household and/or heating appliances, comprising:
- providing a transparent glass or glass ceramic substrate that has a deformation temperature;
- providing a paste having a binder precursor phase, a pigment, a filler, and a screen printing medium, the binder precursor phase comprising a material selected from a group consisting of:
- a glassy material, a glass flux, a glass frit forming material, the pigment comprising an IR-reflecting material, and the filler having a specific molar heat capacity of not more than 5 mJ/(mol·K), wherein the paste has a softening point below the deformation temperature;
- screen printing the paste onto on at least a portion of a main surface of the substrate to obtain a wet layer coating on the substrate;
- and
- firing the substrate having the wet layer thereon at a temperature above the softening point and below the deformation temperature to form the coating.
