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.
Claims22
An article comprising:
- a 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 with a first curvature, a second segment with a second curvature, and a third segment with 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.
1 more element
An article comprising:
- a 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 curved peak having a first curvature;
- a first curved side having a second curvature;
- and
- a second curved side having a third curvature;
- wherein the curved peak is directly connected on one end to the first curved side and on an opposite end to the second curved 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.
5 more elements
An article comprising:
- a substantially symmetrical 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 first segment having a first length, a second segment having a second length, and a third segment having a third length,
- 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 article has an arithmetic mean surface roughness (Ra) of about 0.010 to about 0.250 μm.
2 more elements
An article comprising a curved body having a convex surface and a concave surface, wherein the convex surface has an arithmetic mean surface roughness (Ra) of about 0.010 to about 0.250 μm.
