When bead or pave setting dust the mounting and stones with talcum
powder. This will eliminate the glare, providing a better view of
the metal beads and stones. You can make a “dusting bag” by placing
talcum powder in the center of a cloth handkerchief. Use enough
powder to form a ball about the size of a golf ball. Secure the
loose ends with a rubber band. The banded end will serve as a
handle. Tapping the ball of powder once or twice against the
mounting will provide sufficient powder on the mounting.
