A version of this technique first involves the creation of a “bead” of borax or of microcosmic salt. Halides can be detected in a form of this technique devised by a student of Bunsen at Heidelberg, Fydor Beilstein. Historically, this was the most common technique used to identify sources of thallium poisoning. Both lithium and strontium give reddish-pink results for this technique, which uses a carefully cleaned platinum or nichrome wire loop. For 10 points, name this lab technique in which ions give a colorful result in the presence of heat.
