Abstract (en)

[origin: WO2021121846A1] The invention relates to a method for manufacturing a glass-ceramic article having anti-scratch, anti-grease, anti-soiling and anti-light scattering properties. The glass-ceramic article comprises a surface whose arithmetic surface roughness is between 2 µm and 7 µm, preferably greater than 2 µm and less than 6 µm, preferably between 3 µm and 6 µm, in particular between 3 µm and 5 µm, the roughness being obtained using a chemical surface treatment. The glass-ceramic article is particularly suitable for use as a cooking and/or food preparation surface.
