The word "calx" is often pronounced as "kælks" with the "s" at the end being silent. This spelling is derived from its Latin root, "calx," which means "limestone" or "chalk." The IPA phonetic transcription for "calx" would be /kælks/, indicating the voiced alveolar stop, /k/, followed by the unvoiced alveolar fricative, /s/. While the spelling of "calx" may seem unusual, it serves as a reminder of the word's ancient origins and its use in chemistry and metallurgy.
Calx is a noun that originated from Latin and has multiple meanings depending on the context. In its scientific usage, calx refers to the solid residue obtained when a metallic or non-metallic substance is strongly heated in the presence of air or oxygen. It is commonly known as the oxide or residue left after the process of calcination. Examples of calx include lime, which is produced from heating limestone, or magnesia, obtained from heating magnesium compounds. Calx can also refer to the powdered form of these residues or any similar powder obtained from other processes.
In a historical context, calx refers to a substance used in alchemy that is obtained by calcination. Alchemists believed that calx was the pure form of a metallic substance, which could be further manipulated to change its properties and turn it into gold.
Additionally, in a more general sense, calx can be used to describe any solid residue or deposit that is formed as the result of a heating or calcination process. This usage is not limited to scientific or alchemical contexts but can also extend to everyday situations, such as describing the burnt remains of a fire as calx.
Overall, calx typically refers to the solid residue or powder left behind after a substance is heated, either in a scientific, alchemical, or general sense.
1. Lime, calcium oxide, an alkaline earth occurring in grayish-white masses (quicklime) which on exposure to the air become converted into a white powder of calcium hydrate and calcium carbonate (air-slaked lime); the addition of water to calcium oxide produces calcium hydrate or slaked lime. 2. the heel.

The word "calx" is derived from the Latin term "calx", which means "lime" or "heel". It is also related to the Proto-Indo-European root "*kel-", meaning "to strike" or "to crush". In Ancient Rome, "calx" specifically referred to lime, which was obtained by heating limestone and used in construction and various industrial processes. Over time, the term "calx" came to be used more broadly to refer to any kind of powdery residue left after heating or calcination.
