Abstract
A method includes depositing a glass frit on sidewalls of a plurality of cavities of a shaped article formed from a glass material, a glass ceramic material, or a combination thereof. The glass frit is heated to a firing temperature above a glass transition temperature of the glass frit to sinter the glass frit into a glaze disposed on the sidewalls of the plurality of cavities.
Claims20
A method comprising:
- depositing a glass frit on sidewalls of a plurality of cavities of a shaped article comprising a glass material, a glass-ceramic material, or a combination thereof;
- heating the glass frit to a firing temperature above a glass transition temperature of the glass frit and below a strain point of the glass material, the glass-ceramic material, or the combination thereof of the shaped article to sinter the glass frit into a glaze disposed on the sidewalls of the plurality of cavities;
- wherein the glaze disposed on the sidewalls of the plurality of cavities has an Ra surface roughness of at most about 200 nm;
- and
- wherein the depositing the glass frit comprises dispensing the glass frit from a pen dispenser onto the sidewalls at a dispensing speed of at most about 1.8 mm/s.
