Anvil dust is commonly used in Hoodoo for many different purposes - such as feeding your lodestone, making Goofer dust, carrying in a red flannel bag to bring good luck.
No need to continue to feed your lodestone with magnetic sand, feed it the authentic anvil dust created by a blacksmith on his anvil.
This Authentic Dust Was Collected From Our Late Paw Paw's Shed Unfortunately Blacksmiths aren't as commonly found as they were in days past - real, authentic anvil dust has become hard to find and has been unfortunately replaced by magnetic sand.
