Abstract
Methods of modifying glass-ceramic articles and glass-ceramic articles formed therefrom. The methods include providing a glass-ceramic article having a non-damaged surface, applying a chemical etching solution to the non-damaged surface, and removing the chemical etching solution. The chemical etching solution modifies the non-damaged surface so that from about 0.01 μm to about 2 μm of a depth of the glass-ceramic article is removed. The chemical etching solution modifies the non-damage surface of the glass-ceramic article to form a roughened surface having a reduced gloss value and a target roughness value.
