Wint-O-Green Life Savers work especially well for creating such sparks, because wintergreen oil (methyl salicylate) is fluorescent and converts ultraviolet light into blue light. [ 17 ] [ 18 ] A diamond may begin to glow while being rubbed; this occasionally happens to diamonds while a facet is being ground or the diamond is being sawn during ...
A spark on a spark plug Lightning is a natural example of an electric spark. An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized , electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.
pyrotechnic initiators – produce large amount of heat, flames, and/or hot sparks, used to ignite other compositions gas generators – produce large amount of gas, either high volume at short time (for actuators and ejection charges, often using solid propellants) or controlled flow rate (e.g. chemical oxygen generators , often using thermite ...
Though the striker must have a sharp corner, sharp edge, or a knurled surface in order to produce sparks, carbon steel is not required.
