Lithium Chloride: Lithium Carbonate Dissolved in Hydrochloric Acid, Crystallised above 15 °C (Thorpe 1912)

Lithium carbonate fizzes away in hydrochloric acid, leaving lithium chloride in solution. Crystallised warm, it comes out dry. Result: anhydrous lithium chloride, octahedral crystals that soak up water from the air. Source: Thorpe, Dictionary of Applied Chemistry vol. 3 (1912), p. 339. Not given: amounts and how it is evaporated. Picture drawn by Youblob.
