Tincal, also known as sodium borate or borax is a porous mineral consisting of soft colorless crystals that dissolve easily in water. Among its many possible applications, it’s used in powder form during the process of melting metal or diluted, as a flux, during welding, acting as a supporting element of this process: it slows the oxidation of the metal and helps the solder to run along the joint of the two parts that you want to connect.

Being a word that sounds familiar to most jewelers, it also works here as an invitation to the rest of the public to come to know and interact with this fascinating universe.
