1. Choose a candle color to coordinate with the purpose of your spell. (Green for money, for instance).
2. Carve and dress as desired, then burn the candle.
3. Hold a spoon over the candle flame until black soot forms. (This take a while, it’s a time-consuming process requiring patience.) This soot is lampblack.
4. When sufficient lampblack has been produced, carefully tap it off the spoon and into a bowl.
5.Add spring water, drop by drop, to dissolve the soot and then add gum arabica to thicken the ink.
