When incorporating magical objects into rituals and spell craft, a piece of iron is essential; many altars have at least one piece of iron placed upon them.
A cast iron cauldron is traditional, and a very useful tool for any modern witch, for tasks ranging from burning herbs and incense to magical scrying and divination, to kitchen witchery and cooking magic. Iron is a symbol of strength, protection, and life-giving warmth, as it is seen as a combination of the elements of Earth and Fire.
The metaphysical and paranormal properties of iron are longstanding in history. The scent of human blood is aromatic with the presence of iron, therefore iron itself is said to be a direct link to the life force of mankind.
