[26] The subsequent yr, he noted this was erroneous and which the ore contained primarily gold and an unidentified steel similar to antimony. Immediately after a radical investigation that lasted three years and included in excess of fifty assessments, Müller get more info decided the particular gravity from the mineral and observed that when heated, the new metallic offers off a white smoke that has a radish-like odor; that it imparts a pink shade to sulfuric acid; Which when this Resolution is diluted with drinking water, it's got a black precipitate. However, he was not able to determine this metallic and gave it the names aurum paradoxum (paradoxical gold) and metallum problematicum (problem steel), as it did not exhibit the properties predicted for antimony.[27][28][29]
