More About Mary the Jewess

Mary the Jewess and her alchemical contributions are documented by Zosimos of Panopolis in his text Peri kaminon kai organon (On Furnaces and Apparatuses), which may be itself based on a text by Mary. He also quotes her extensively in The Coloring of Precious Stones.

According to Zosimus and later renderings of Maria's writings, alchemy was like sexual reproduction, with different metals being male and female. She described the oxidation of metals, and saw in that process the possibility of transforming base metals into gold. The saying credited to Mary the Jewess, "Join the male and the female, and you will find what is sought," was used by Carl Jung.

Inventions

The name of Mary the Jewess survives in two terms used in chemistry. The water-bath, a term used for both a process and a device, is also called in Romance languages the bain marie or baño maria.

The term is still used in cooking today. The bain marie uses heat from water in a surrounding vessel to keep a consistent temperature, something like a double boiler.

"Mary's black" is also named for Mary the Jewess.  Mary's black is a black sulfide coating on metal which is produced using the process of kerotakis.

Mary the Jewess also invented and described the alchemical apparatus and process called the kerotakis and another apparatus called the tribokos. (See Patai, below, for drawings.)

Later Writings About Mary the Jewess

Variations on the story of Mary are told in sources after Zosimus. The church father Epiphanius, bishop of Salamis, mentions two writings by Mary the Jewiss, Great Questions and Small Questions, where he credits her with a vision of Jesus. Mary's story is also retold in Arabic writings where she is supposedly both a contemporary of Jesus (having carried the infant Jesus) and Ostanes, a Persian brother-in-law of Xerxes, who lived about 500 BCE.
