Berzelius i Gahn analitzaren la pirita i detectaren que el precipitat vermell produïa una olor de rave picant quan es cremava. Aquesta olor no era característica de l'arsènic, però es coneixia una olor comparable dels composts de <a href="/wiki/Tel%C2%B7luri" title="Tel·luri">tel·luri</a>. Berzelius escriví una carta a <a href="/w/index.php?title=Alexander_John_Gaspard_Marcet&action=edit&redlink=1" class="new" title="Alexander John Gaspard Marcet (encara no existeix)">Alexander John Gaspard Marcet</a> (1770-1822), un metge nascut a Ginebra i convertit en ciutadà britànic el 1800, on deia que es tractava d'un compost de tel·luri. No obstant això, l'absència de composts de tel·luri als minerals de la mina Falun portà finalment a Berzelius a reanalitzar el precipitat vermell, i el 1818 envià una segona carta a Marcet descrivint un element recentment trobat similar al sofre i al tel·luri.
