Making gems. Part one: fish black

 

We’re back! Just for a one-off mini-series, though. Probably.

We have come to the final experiment of this series!

Out of all the recipes we chose, this one probably had us scratching our heads the most: The Rasaprakāśasudhākara’s second recipe for making silver. It features uncertain, and exotic materials, and an unusual method.

Argentifaction – Making silver

When Andrew and I selected recipes for this series of experiments, we favoured recipes that appeared simple. Method 14 for making silver made the cut because it was short and featured only a few ingredients: copper, brass, bronze, arsenic sulfide, and silver. Nothing too fancy.

We have arrived at the eighth, and for us, final procedure! This step is called the stimulating or kindling (dīpana) of mercury. And here is what the text (Rasahṛdayatantra, chapter 2, verse 11) tells us about this step:

In the sixth procedure, the mercury was supposed to regain its power, which had been suppressed through the earlier cleansing procedures.

Nine months into this experiment, we have arrived at the fifth procedure: pātana. This procedure is meant to rid the mercury once and for all of any residual amounts of tin and lead, which are understood as contaminants that render mercury poisonous. The procedure involves preparing a copper-mercury mixture.
