A muffle adapted to receive associated material/parts from an associated furnace, the muffle comprising:
- a planar lower surface;
- first and second sidewalls extending upwardly in parallel relation from opposite, first and second edges, respectively, of the lower surface;
- and
- an upper surface extending from upper ends of the first and second sidewalls, wherein the upper surface has at least a portion thereof that is a concave, arch-shape.
A method of forming a muffle comprising:
- providing a lower surface;
- positioning first and second sidewalls along opposite edges of the lower surface that extend upwardly therefrom;
- and
- securing an upper surface to the sidewalls wherein at least a portion of the upper surface has a concave arch-shape.
