Argon provides an inert atmosphere in which welded metals will not oxidise. And what's it like? Double glazing is even more efficient if the gap between the two panes of glass is filled with argon rather than just air because argon is a poorer conductor of heat. Then you cover the Tickle with an argon blanket and react with hot magnesium [at 850 degrees C] to get the metallic element. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. In the same way that lead salts are added to glass to make sparkling crystal glassware, uranyl salts give a very beautiful and translucent yellow-green colour to glass, although glassmakers have experimented to produce a wide range of gem-like colours.
