Bain-marie

A 5-qt. enamel pail or bain-marie jar is fitted with two mechanical stirrers (Note 1) placed off center, a thermometer for reading low temperatures, and a dropping funnel, the lower end of which is placed just over the vortex created by one of the stirrer blades, so that each drop of added liquid is immediately mixed with and diluted by the chilled reaction mixture. 

A variety of enameled-steel pots known as bain-marie is available from the American Specialty Company, Rochester, New York.

My father s alchemical notebook did not go beyond this stage. He had prepared the bain-marie and cucurbit but gone no further. His notes stopped on March 28, 1726, and I knew why. In recent years, his fingers had grown so stiff that I had to perform the delicate operation of sealing the neck of the cucurbit to the still head for him. It had been my job to mix the paste, handle the glass, and suspend it over the bain-marie his, to record the operation. He had stopped work because he simply hadn t the heart or the physical skills to go on without me. 

I studied him his somber black coat, the tilt of his head, the concentration in his eyes. Meanwhile, the water in the bain-marie hissed, another carriage set off outside, and faintly, from a distant corner, I thought I heard my father s cough. Now I knew why I had been led through the labyrinth of the miscarried embryo, the bleak homecoming, the dead babies, the furnace shed—it was all to show me this. 

ALL THIS TIME, through the crimson party and beyond, the distillation had continued the water in the bain-marie simmered and a cloud of condensation gathered on the still head, trickled down the delivery spout, and dripped into the receiver. When there had been a period of four hours or more and no moisture was collected, we poured the cloudy distillate from the receiver back into the flask containing the crusty alchemical residue, and began again. 

I felt the blows the length of my spine and rushed to the laboratory to check that nothing had been damaged. The water in the bain-marie was lapping the sides and the cellar door burst open. It s begun, moaned Gill. 

Resorcinol paste is compact and dilEcult to apply. It is easily softened by putting it in a bain-marie at 45° for around 10 minutes. If that is not possible, small blocks of paste should be applied to the patient s skin. Heat from the skin will slowly melt the paste and make it easier to spread, although the resorcinol may penetrate too deeply where contact time has been longer.

The heat from the athanor was communicated as needed to the balneum marts (balneum marie or bain marie—hot-water bath) accessory on the right and also to the sand bath accessory on the left in Figure 116a.

The athanor itself was commonly used for operations involving a sealed vessel or philosopher s egg.
