Magic metal that can absorb and negate elemental magic, at the cost of generating heat (melting the metal if it absorbs too much). This ability lets Silverstone be used for both storing magical energy to be used later and to protect people, objects, or structures from mystical attacks.

The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
In hydrolysis, the noble-metalliferous products are dissolved either in aqua regia (consisting of hydrochloric acid and nitric acid) or in a hydrochloric acid and chlorine gas in solution. Subsequently, certain metals can be precipitated or reduced directly with a salt, gas, organic, and/or nitro hydrate connection.
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.

Mischmetal (from German: Mischmetall – "mixed metal") is an alloy of rare-earth elements. It is also called cerium mischmetal , or rare-earth mischmetal . A typical composition includes approximately 55% cerium , 25% lanthanum , and 15~18% neodymium , with traces of other rare earth metals totaling 95% lanthanides , plus 5% iron.
