Skull candles are used when working upon the head of oneself or another. These types of work often deal with the mentality, thought processes, mental health, psychology, and the spirit of a person. They may also be employed for working with the dead and the ancestors. The type of work done with them is often informed by the color of the candle.
White Skulls are used for uncrossing, healing, spiritual focus, seeking mental clarity, and removing mental blockages. Within certain traditions they may also be used as an offering for honoring and calling upon spiritual ancestors and the Mighty Dead.
Red Skulls are used for works of inspiring passion, encouraging love, kindling lust, and for strengthening personal power. Within certain traditions they may also be used as an offering for honoring and calling upon blood ancestors and the Beloved Dead.
Black Skulls are used in works of hexing, crossing, and cursing, as well as for reversing harm. They may be used for causing confusion, strife, mental imbalances, delusions, and illness. Or dressed with reversing oil to turn back work being done against you. Within certain traditions they may also be used as an offering for honoring and calling upon wandering shades and the Blasted Dead.
Green Skulls are used in works of financial importance. They may be used to inspire a pay raise at work, get a loan, find investors, pressure someone to pay a debt, etc.
To use, the candle should be carved with the name and birth date of the individual whom they are meant to represent. The bottom of the candle may also be carved out and items such as hair and personal effects from the individual they are meant to represent may be added, or in other cases certain dusts and graveyard dirt may be added. The candle is then dressed with and appropriate conjure oil while being prayed over and named for the person the work is being for.
