The heads of matches boast a stuff called diatoms, which are living thing organisms recovered in oxide supported dirt and are utilized in the harvest of matches. The shells in these smallest organisms encompass silica, a muscular textile that has the capability to survive fires.

There is no curb to the creativeness of an firebug when location one of these inclination.
If a detailed furrow of the law-breaking country unveils candle residue, a cigar or coffin nail butt, or the remnants of an electrical device, CSI investigators have unconcealed a viable igniting device.
