Bain Marie - The Bain Marie is a warm alchemical bath. Chemically, it is a double-boiler in which a container of water is suspended in a simmering cauldron. Psychologically, it is the gentle warmth of emotionally centered meditation used in the Dissolution process. The Bain Marie was named after Maria Prophetissa, a Jewish alchemist who wrote much about the methods and equipment of the Water operations of Dissolution and Distillation.
Balsam - A balsam is a resinous or waxy semi-solid compound that captures the essence of a liquid medicine or perfume. To Paracelsus, the balsam was the "interior salt" that protected the body from decomposition, and earlier alchemists considered the Balsam of the Elements to be the Quintessence, the result of the Conjunction of alchemical principles. Because of it amalgamating ability, mercury was considered the balsam agent of the metals. In the chemical arcana, Liquor Hepatis mixed with fat or wax was known as the Balsam of the Soul.
Basilisk - The Basilisk is a symbolic alchemical creature said to have the head of a bird and the body of a dragon. The wingless serpentine animal was hatched from a hermaphroditic cock's egg and nursed by a serpent. Psychologically, the Basilisk represents the melding of our higher and lower natures in Conjunction, a process that must be continued in the next three operations of alchemy for this "Child of the Philosophers" to become the Living Stone of the fully integrated Self. Biologically, the Basilisk represents the mammalian embryology, the genetic replaying of the stages of evolution within the egg or womb. The Basilisk also has chemical connotations, which probably have to do with a metallurgical process involving cinnabar.
