How to Handle Potassium Hydroxide - Soap Queen
Adding an acid (vinegar) to a base (lye) creates a chemical reaction that releases heat which burns. Additionally, just the act of putting vinegar on a lye burn hurts. For this reason, both the Material Safety Data Sheet and the Agency for Toxic Substances & Disease Registry recommend rinsing lye burns with water for 15 minutes.

What role does cryolite play in Hall Heroult process ? - …
Although a molten aluminium salt could be used instead, aluminium oxide has a melting point of over 2,000 C (3,600 F) so electrolyzing it is impractical. In the Hall–Héroult process alumina, Al2O3, is dissolved in molten cryolite, Na3AlF6, to lower its melting point for easier electrolysis,it also increases conductivity of the solution.
