Abstract
The present disclosure relates to non-metallic articles that can be burner shields having grease flow control and/or chemical resistance. The present disclosure also relates to glass-ceramic burner shields that can have grease flow control and/or chemical resistance, and preferably both.
Claims29
A burner shield in a cooking apparatus comprising:
- comprising:
- an entirely curved body having a width and a height in a width to height ratio of 0.5 to 4, the entirely curved body comprising a material selected from the group consisting of glass-ceramic, glass, ceramic, quartz-glass, and combinations thereof,
- wherein the body comprises a first segment that is non-planar and has a first curvature, a second segment that is non-planar and has a second curvature, and a third segment that is non-planar and has a third curvature,
- wherein the first segment is between the second segment and the third segment, and
- wherein the second curvature and the third curvature are different than the first curvature.

A burner shield in a cooking apparatus comprising:
- comprising:
- an entirely curved body having a width and a height in a width to height ratio of 0.5 to 4, the entirely curved body comprising a material selected from the group consisting of glass-ceramic, glass, ceramic, quartz-glass, and any combinations thereof, wherein the body comprises:
- a peak that is non-planar and has a first curvature;
- a first side that is non-planar and has a second curvature;
- and
- a second side that is non-planar and has a third curvature;
- wherein the peak is directly connected on one end to the first side and on an opposite end to the second side,
- wherein the second curvature is substantially equal to the third curvature, and
- wherein the first curvature is different than the second and third curvatures.

A burner shield in a cooking apparatus comprising:
- comprising:
- a substantially symmetrical and entirely curved body comprising a material selected from the group consisting of glass-ceramic, glass, ceramic, quartz-glass, and any combinations thereof,
- wherein the curved body comprises a first segment that is non-planar and has a first length having a first opening angle from 10 to less than 180 degrees, a second segment that is non-planar and has a second length having a second opening angle from 5 to 50 degrees, and a third segment that is non-planar and has a third length having a third opening angle from 5 to 50 degrees,
- wherein the first segment is between the second and third segments,
- wherein the first length is different than each of the second length and the third length, and
- wherein the curved body has a convex surface and a concave surface, and wherein the convex surface has an arithmetic mean surface roughness (Ra) of about 0.010 to about 0.250 μm.
