One of the oldest and most traditional forms of magic involves carefully selecting items that are then placed into some type of container for the purpose of achieving a goal. We know this to be true because archaeologists and anthropologists periodically unearth such items. Nothing about these spells are random. For example, English "witch bottles" are jugs containing different kinds of objects and fluids that are sealed and typically buried to keep witches away. The practice is international and remains a vital part of magic.

Container spells are used for all sorts of purposes and, despite their antiquity, are an increasingly popular style of spellcasting. Ingredients are generally found in the home and are personal to the creator. Containers may be portable, such as mojo hands or charm bags. They may also be stationary, such as honey jar spells, which involve placing items into a jar, covering them with honey, closing the lid, and then burning a candle on top of the jar.

Starr Casas is an acknowledged authority and master on Conjure-style container magic. In Container Conjure, Mama Starr teaches listeners how to load their own containers and maintain control over their spellcasting. Starr's container magic is not limited to jars; she also uses dolls, light bulbs, sachets, fruit, and other organic material as "containers."
