Heating Mantles - Facilities Management

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 ...

Mantle Chemistry and Accretion History of the Earth

Mantle Chemistry and Accretion History of the Earth

Abstract. The chemical composition of the Earth’s primitive mantle (present mantle + crust) yields important information about the accretion history of the Earth. For the upper mantle reliable data on its composition have been obtained from the study of primitive and unaltered ultramafic xenoliths (Jagoutz et al. 1979).
