8" Triple Moon Pentagram Copper Bowl
Offering bowls have been used for centuries for spiritual and religious purposes. In modern Paganism, an offering bowl may be used upon one's altar or during ritual, and may be used for many purposes. One purpose could be to "charge" an item or magical component. Some may use their offering bowls as exactly that (an offering to the divine) as a symbolic token of appreciation. Some may use their bowls to hold water for cleansing. Others may use certain vessels to burn incense within.
