what do you use salt petre for
Salt Petre (potassium nitrate) (Bulk, 8 oz) Product Description. Throughout recorded history Potassium Nitrate, more commonly known as Salt Petre, has been used for preserving food especially meat products like sausage and salamis. This ingredient must be measured with a gram scale and used with extreme caution.
Magically speaking, Saltpeter has a long, long, long history in hoodoo as an agent of magical protection in spritual baths and floor washes and as a shoe-sprinkle. Also, because it is an ingredient in Gunpowder, it is used in formulae which are hoped to produce quick (explosive) action, such as Block-Buster.
