Smelters weren’t fond of the ores either. The miners thought the cruel kobold had changed the silver into worthless rocks. Cobalt comes from the German word ‘kobold’ – small mountain elves or goblins. She used several other names – magnesia, wismuth or the secretive ‘minera’ – even though German miners had earlier coined the word cobalt to describe the ores she studied. Wallich never used the word cobalt in her books. In spite of her detailed research Wallich, like the other chymists, was unable to create the philosophers’ stone. Wallich became a much sought-after chymist following the publication of her books. When heated and cooled, the compounds have colours ranging from rose, violet blue, sky blue and grass green. She is credited with discovering and reporting many thermochromic effects of cobalt compounds. Wallich’s books describe numerous chemical reactions in detail. Wallich’s goal was to produce the philosophers’ stone – a substance that could turn base metals such as lead and tin into silver and gold. Dorothea Juliana Wallich was interested in chymistry (a term that covers both alchemy and chemistry). Thirty years prior to Georg Brandt’s published account of separating cobalt from bismuth, a young German woman had already published three books about her research using ores that contained cobalt.
