The Witches Bell in Magick

The bell stands in the North of the circle and is an Earth symbol.
It is an optional tool and can be made from either crystal or protective brass.
Best for magick is the kind that you strike.
The bell is traditionally rung nine times at the beginning and close of each ritual; the person ringing the bell should stand in the South of the circle, facing North. (Nine is the magical number of completion and perfection.)
It is also rung to invoke the protection of angels or the power of a deity and in ceremonies to welcome departed members to the circle.
You can also sound the bell in each of the four elemental quadrants, before creating the invoking pentagram, to request the presence of each elemental guardian.
It can also be sounded as you pass your chosen symbol around each quadrant of the circle.
However, you should not use the bell to excess – it is better under-utilised
