Abstract
A textured glass-based article with multiple haze levels is provided. The textured glass-based articles are produced by utilizing a combination of etching and mechanical polishing to produce the multiple haze levels.
Claims30
A method, comprising:
- texturing a surface of a glass-based substrate to produce a textured glass-based substrate having a first thickness t1, a first surface roughness Ra1, and a first haze H1;
- and
- polishing a region of the surface of the textured glass-based substrate to produce a glass-based article with a surface comprising a polished region with a second thickness t2, a second surface roughness Ra2, and a second haze H2,
- wherein Ra1>Ra2, H1>H2, t1>t2, and the glass-based article comprises a region having t1, Ra1, and H1.

1 more element
A method, comprising:
- polishing a region of a surface of a glass-based substrate with a rotary polishing tool to produce a glass-based article with a surface comprising a polished region,
- wherein:
- the pressure applied to the glass-based substrate by the rotary polishing tool is controlled to be in the range greater than or equal to 1 psi to less than or equal to 15 psi,
- the rotary polishing tool comprises an abrasive component embedded in a binder,
- the glass-based substrate has a first thickness t1,
- the polished region of the glass-based article has a second thickness t2,
- the glass-based article comprises a region having a thickness t1, and t1>t2.
