Testing for gold with acid
focuses around the fact that gold is a noble metal which is resistant to change by corrosion, oxidation or acid. The acid test for gold is to
rub the gold-colored item on black stone (or touchstone), which will leave an
easily visible mark. The mark is tested by applying nitric acid, which dissolves the mark of any item that is not gold. If the mark
remains, it is tested by applying a combination of nitric acid and hydrochloric acid (aqua
regia—or ‘royal water’). If
the mark is removed, then this test dissolved the gold, proving the item to be
genuine gold. (http://en.wikipedia.org/wiki/Acid_test_(gold))
I found this fascinating. I’ve
often wondered why suffering affects people differently. Some people dissolve
into bitterness early, with the first acid test. Their mark on this world
disappears, their life and accomplishments of little value to others.
In contrast, those who are
golden--noble and pure to the elemental level—are resistant to change by
corruption. Their hearts are not darkened even with prolonged exposure to
pollutants. They only dissolve or surrender to the King. And when they finally
change, they take on the Christ-like qualities that leave a lasting mark.
