In the above article, Randall Munroe mentions that liquid tungsten is difficult to study because of its extremely high melting point. Because of this property, containers for the tungsten tend to melt before the metal itself. This might be a fairly elementary question, but given this difficulty, what methods do modern chemists use to study it, or other materials with extreme melting points?
