Lead has a shiny chrome-silver luster when it is melted into a liquid.

Famous quotes containing the word lead:
“‘Whence thou return’st, and whither wentst, I know;
For God is also in sleep; and dreams advise,
Which he hath sent propitious, some great good
Presaging, since, with sorrow and heart’s distress,
Wearied I fell asleep: but now lead on;
In me is no delay; without thee here to stay,
Is to go hence unwilling; thou to me
Art all things under Heaven, all places thou,”
—John Milton (1608–1674)
“They be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.”
—Bible: New Testament Matthew 15:14.
“We shall do better to abandon the whole attempt to learn the truth ... unless we can trust to the human mind’s having such a power of guessing right that before very many hypotheses shall have been tried, intelligent guessing may be expected to lead us to one which will support all tests, leaving the vast majority of possible hypotheses unexamined.”
—Charles S. Pierce (1839–1914)
