Abstract
An oven muffle is provided with a cavity wrapper disposed between and connected to each of a bottom cap and a top cap. A lower rack-support embossment is formed on a peripheral skirt of the bottom cap, and at a position vertically below a seam where the cavity wrapper and the bottom cap are joined. The peripheral skirt can have first and second curved sections with a linear section disposed therebetween, when viewed in cross-section. The lower rack-support embossment has embossed features, each having a respective contour that is or converges to tangent to the linear section of the peripheral skirt.
