Is (used for "Scrying" or Fortune-Telling)

"The ancient art of clairvoyance achieved by concentrating upon an object-- usually one with a shiny surface-- until visions appear."

The term scrying comes from the English words descry which means 'to make out dimly' or 'to reveal.'

The services of a scryer typically are sought for predictions of the future, answers to question, solutions to problems and help in finding lost objects or tracking down criminals.

Few witches throughout history have used crystal balls which are very heavy and expensive.

In England, glass-ball fishing floats are commonly used, as are witch balls, colored glass balls intended to be hung in homes to keep out witches....

The favored speculum is the magic Mirror, preferably one with a concave side painted black.

Witches may make magic mirrors themselves, painting and decorating them with magic Sigils during the Waxing of the Moon and consecrating them in rituals like other working tools.

Another scrying tool used by witches is a cauldron painted black on the inside.

The witch fills the cauldron with water and drops in a silver coin to represent the Moon in the night sky. 

As in other magic work, witches scry within a Magick Circle.
