Blessing of Chalk
A blessing of chalk, used to consecrate and prepare chalk for use in rituals and workings. Take chalk in a day and hour of Mercury, preferably when the Moon is waxing and in the sign of Virgo. Sprinkle the chalk with holy water and say the following over it.
O God, heavenly father, eternal spirit, fountain of light, present in all places and father of all things, who fashioned the world in the seven days of creation, bless this creature of chalk that it may be used for the aid, defense, and salvation of the human race. O Lord, through the invocation of Your holy name ELOHIM TZABAOTH, grant this chalk the power and blessing to preserve that which is just and true from losing its justice and truth. Just as you provided safety for your Word eternal, so too may this chalk provide the same for us and in all purposes that it shall serve us. Amen.
This consecration could also equally be used for any writing instrument, like pens, pencils, or charcoals. For the less Abrahamic or Hermetic, an appeal to Mercury, Hermes, Thoth, Odin, or a similar scribe or language god would work as well.
