1. Methyl cellulose has been used to safely simulate molten materials , as well. 2. This can be dangerous as the molten material can be blown substantial distances. 3. Because these minerals were denser than the molten material around them, they sank. 4. The air jet is then used to blow away molten material . 5. The molten material cooled and solidified before reaching the surface. 6. An accurate identification of the molten materials could help explain the thermal failure mode. 7. The key to the magnetism, according to geophyicists, is the molten material in the Earth's outercore. 8. Perhaps the reason Norris is so dynamic, researchers say, is that there's molten material beneath the basin. 9. It is thought that this is caused by the cooling of molten material , or possibly tectonic movement. 10. Migmatites are not crystallized from a totally molten material , and are not generally the result of solid-state reactions.
