A method for purifying powdered silicon carbide is in the form of a starting material to form a silicon carbide having a purity of at least 99.9%. This method has the following method steps: providing a starting material having a grain size of less than 100 μm and a silicon carbide content with at least 98% purity; and heating the starting material in a vacuum or oxygen-free atmosphere to a temperature above 1700° C. over a period of at least 8 minutes.

A method of manufacturing spectacle arms includes grooving an inner face of a first cover plate to form grooves and providing a gauge with longilineal inserts. Front and rear bridges join front and rear ends of the longilineal inserts and provide front and rear indexing. The gauge is set on the inner face of the first cover plate such that the longilineal inserts are disposed in the grooves and a second cover plate is pressed and bonded on the inner face of the first plate such that the longilineal inserts are inserted between the first and second cover plates. The plates are cut around the longilineal inserts with a cutting tool after the cutting tool is positioned and held in place using corresponding front and rear tool indexing.

The invention relates to a spectacle arm (2) comprising a first frame part (5) and at least one second decorative sleeve part (6) that is rotatably mounted about the frame. The invention is characterized in the said arm includes means for indexing the rotational position of the sleeve defining a plurality of indexing positions corresponding to positions in which the sleeve is in stable equilibrium, said indexing means including at least one resiliently deformable element (80) linked to one of the above-mentioned two parts and a bearing surface supporting the resiliently deformable element, provided on the other of the two parts and having a plurality of indexing areas, such that: at each indexing position, the resiliently deformable element bears against one of the indexing areas in order to immobilize the sleeve or keep same in the corresponding indexing position; and between two indexing positions, as the sleeve is rotated, the resiliently deformable element is resiliently deformed between two indexing areas of the bearing surface in order to allow the sleeve to pass from one indexing position to the other.
