One end of a horizontal cylindrical specimen was subjected to a liquid petroleum gas (LPG) flame. There was no burning without melting. Mg–5%Gd, Mg–3%Ca, and Mg–5%Ca resisted burning. Otherwise, on sufficient LPG flame exposure, there was melting and specimen tip ignition. Any hot detached blob continued to burn until consumed, except for Mg–1%Ca, Mg–3%La, Mg–3%Ce, and Mg–5%Nd. The burning specimen tip extinguished upon withdrawal of the LPG flame.
