Besides its relatively low upper explosive limit, carburetted acetylene
exhibits a higher temperature of ignition than ordinary acetylene, which
makes it appreciably safer in presence of a naked light. It also
possesses a somewhat lower flame temperature and a slower speed of
propagation of the explosive wave when mixed with air. These data are:
