Abstract
Disclosed are a glass-ceramic having increased clarity of colors by controlling a microstructure and improved cleanability by a polishing process and a cooktop including same. The glass-ceramic according to an embodiment of the present disclosure includes: a glass material; and an uneven layer formed on the glass material, wherein hexahedral crystals may be included as a microstructure.
Claims18
A glass-ceramic comprising:
- a glass material comprising an uneven layer,
- a coating layer disposed on the glass material, wherein the coating layer comprises an upper printed layer, and
- a lower printed layer disposed under the glass material,
- wherein the uneven layer comprises micro-dimples.
1 more element
A cooktop comprising:
- a glass-ceramic;
- wherein the glass ceramic comprises:
- a glass material comprising micro-dimples having at least one of widths in a range from 40 μm to 150 μm or depths in a range from 30 μm to 74 μm, so as to improve cleanability and to prevent the decrease in clarity of color;
- a coating layer disposed on the glass material, wherein the coating layer comprises a display layer, the display layer having transmittance in a range from 85% to 90% for preventing diffused reflection and for having transparency;
- and
- a lower printed layer comprising a heat-resistant shielding layer.
