ABSTRACT OF THE DISCLOSURE Process for the manufacture of combustible articles by embossing combustible paper and combustible articles thus produced. The invention relates to a process for the manufacture of combustible dish-shaped articles of revolution with circular external outlines from combustible paper containing nitrocellulose by embossing at least one combustible paper disc comprising a central part and a peripheral part consisting of a plurality of portions separated from each other by radial slits the length of which is smaller than the radius of the said disc and the width in which is at least equal to the minimum width required to prevent the overlapping of the said portions when the disc is deformed by embossing. The invention also relates to combustible dish-shaped articles of revolution with circular external outlines, consisting of at least one sheet of combustible paper containing nitrocellulose and in particular those produced by the process according to the invention. These articles have their essential application as components for combustible cases and especially as combustible bottoms or as combustible lids.
