Drop twelve drops of genuine oil of rhodium on a lump of loaf-sugar ; grind this wel in a glass mortar, and mix it thoroughly with three pounds of orris powder.

Orris is the part of the florentine iris you don′t see — the rhizome.(..)The ancient Egyptians and Greeks learned that the bland-smelling orris root would take on a remarkable fragrance if dried for at least two years.

Next place your hair, the rose quartz, some of the orris root powder, and the candle drippings into the box.
