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.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
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.

Ars Magica is a role-playing game set in 'Mythic Europe' – a historically grounded version of Europe and the Levant around AD 1200, with the added conceit that conceptions of the world prevalent in folklore and institutions of the High Middle Ages are factual reality (a situation known informally as the "medieval paradigm").
Baryte, barite or barytes (/ ˈ b ær aɪ t, ˈ b ɛər-/ BARR-eyet, BAIR-[7] or / b ə ˈ r aɪ t iː z / bə-RYTE-eez [8]) is a mineral consisting of barium sulfate (BaS O 4). [3] Baryte is generally white or colorless, and is the main source of the element barium.
Eutectic alloys for soldering, both traditional alloys composed of lead (Pb) and tin (Sn), sometimes with additional silver (Ag) or gold (Au) — especially Sn 63 Pb 37 and Sn 62 Pb 36 Ag 2 alloy formula for electronics - and newer lead-free soldering alloys, in particular ones composed of tin, silver, and copper (Cu) such as Sn 96.5 Ag 3.5.
Lanthanum metal is obtained from its oxide by heating it with ammonium chloride or fluoride and hydrofluoric acid at 300–400 °C to produce the chloride or fluoride: [17] La 2 O 3 + 6 NH 4 Cl → 2 LaCl 3 + 6 NH 3 + 3 H 2 O. This is followed by reduction with alkali or alkaline earth metals in vacuum or argon atmosphere: [17] LaCl 3 + 3 Li ...
