But Ren\u00e9 Ha\u00fcy deducted that this was due to them both containing the same as yet unknown element and approached a specialist in chemical analysis Nicolas Louis Vauquelin. At the time it was common practise to taste substances as part of the analysis and Vauquelin tasted the substance which was sweet, and unknown to him toxic, so Vauquelin named the substance &#8216;glyceynum&#8217; from the Greek word \u2018glykis\u2019 meaning sweet.<\/span><\/p>\n<p class=\"MsoNormal\" style=\"text-align: justify;\"><span style=\"font-family: 'Verdana','sans-serif';\">Beryllium was isolated separately by French chemist Antoine Alexandre Bussy and German physician and chemist Friederich W\u00d6hler in 1828. They both reacted beryllium chloride and potassium in a platinum crucible and yielded beryllium and potassium chloride. Friederich W\u00f6hler renamed the element &#8216;beryllos&#8217; from the mineral beryl however Bussy preferred the name &#8216;glucinium&#8217; and it wasn&#8217;t until 1957 that it was officially called beryllium. <\/span><span style=\"font-family: 'Verdana','sans-serif';\">\u00a0<\/span><\/p>\n<\/blockquote>\n<h2 class=\"MsoNormal\" style=\"text-align: justify;\"><span style=\"font-family: 'Verdana','sans-serif';\"><a id=\"SourcesofBeryllium\" name=\"SourcesofBeryllium\"><\/a>Sources<\/span><\/h2>\n<blockquote>\n<p class=\"MsoNormal\" style=\"text-align: justify;\"><span style=\"font-family: 'Verdana','sans-serif';\">Beryllium occurs naturally and can be found in bertrandite and Beryl ore.
