Blueing Balls (compressed sodium carbonate with anil dye) are used for gambling luck, drawing good spirits, protection and success.
Blueing Balls are used in old-time spiritual work for bringing in positive spirits, cleansing, good luck and success and are safe for laundry and bathing (but are not to be taken internally).
Some ideas for magical uses:
Add a Blueing Ball, a tablespoon of sugar and three Bay Leaves to your bath water for a luck and success bath.
Mix a Blueing Ball, a tablespoon of crushed Alum, and Hyssop to create a cleansing bath.
Dissolve a Blueing Ball in a bowl of water and place on your altar to invite in good spirits and keep negative ones at bay.
Dissolve a Blueing Ball in water and sprinkle or spray around your home to uncross and protect against work against you. (Be aware that there is blue dye in Blueing Balls, so do not spray on light-colored objects.)
Carry a Blueing Ball, 9 Chamomile flowers and a Lucky Hand Root in a red flannel mojo bag for good gambling luck.
For in-depth information on how to use this and other herbs and roots magically, I recommend Hoodoo Herb and Root Magic and Cunningham's Encyclopedia of Magical Herbs, both of which can be found in our Books section.
