A heating mantle can easily generate enough heat to vaporize most organic materials and will melt a flask if used on full power. Always plug the heating mantle into a grounded variable voltage transformer or percentage timer control (which runs at full power but cycles on and off to control the heat). Such devices are often known by the trademarked name, Variac (below, left) …
