Alchemy was a series of practices that combined philosophical, magical, and chemical experimentation. One goal of European alchemists was to create what was known as the Philosopher’s Stone, a substance that when heated and combined with a non precious metal like copper or iron (known as the “base”) would turn into gold.
[1] [2] For many centuries, it was the most sought-after goal in alchemy. The philosopher's stone was the central symbol of the mystical terminology of alchemy, symbolizing perfection at its finest, divine illumination, and heavenly bliss. Efforts to discover the philosopher's stone were known as the Magnum Opus ("Great Work"). [3]
K 2 CO 3; Pearlash – formed by baking potash in a kiln. Milk of sulfur (lac sulphuris) – formed by adding an acid to thion hudor (lime sulfur). Natron/soda ash/soda – sodium carbonate. Na 2 CO 3; Nitrum flammans – ammonium nitrate. Sugar of lead – lead(II) acetate, formed by dissolving lead oxide in vinegar.
It is described as lead(II,IV) oxide, or structurally 2PbO·PbO 2, and is the best-known mixed valence lead compound. Lead dioxide is a strong oxidizing agent, capable of oxidizing hydrochloric acid to chlorine gas. [77] This is because the expected PbCl 4 that would be produced is unstable and spontaneously decomposes to PbCl 2 and Cl 2. [78]
In alchemy, fixation is a process by which a previously volatile substance is "transformed" into a form (often solid) that is not affected by fire.It separates the substance or object and puts it back in the same or different shape at a subatomic level.

Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69 g/cm 3 when liquid to 14.184 g/cm 3 when solid. The coefficient of volume expansion is 181.59 × 10 −6 at 0 °C, 181.71 × 10 −6 at 20 °C and 182.50 × 10 −6 at 100 °C (per °C). Solid mercury is malleable and ductile, and can be cut with a knife ...
