If a clean nichrome wire is dipped into a metal compound and then held in the hot part of a Bunsen flame, the flame can become coloured (Figure 16.3). Certain metal ions may be detected in their compounds by observing their flame colours (Table 16.2). 

The differences noted in deflagration hazards as a function of the methods of ignition (either by a fuse head or by a Nichrome wire heater) have been examined and are shown in Table 3.29. No noticable difference in the rate of pressure increase due to deflagration was obserbed for either of the methods of ignition. No effect in the assessment of deflagration hazard was observed when polyvinylidene films were used for wrapping the igniters and the samples. 

Pre-clean a platinum or nichrome wire by holding it in the hottest part of the Bunsen flame (just above the central blue cone) until there is no coloured flame from the wire. Cool, then dip the cleaned wire into the moistened solid sample. Place the wire at the edge of the Bunsen flame (Fig. 19.3) and record the colour of the flame from the sample (see Table 19.2).
