Alum is a mineral salt commonly believed to bring protection and luck. To stop gossip take a dime sized amount of alum powder and put it into a muslin bag. Write the interfering person's full name on a piece of paper and place it in the sack with the alum. Just as alum puckers up the mouth, this charm bag will keep the person you have named from gossiping about you or messing in your personal business. A lump of alum, a piece of pyrite, and a pinch of salt peter carried together in a red flannel bag dressed with Hoyt's Cologne makes a great all-mineral mojo bag for luck in gambling. Alum Powder is sold as a curio.
