Bible Verses About Metals: Freed from dross by fire

The house of Israel hath been to Me for dross, All of them are brass, and tin, and iron, and lead, In the midst of a furnace--dross hath silver been,

A gathering of silver, and brass, and iron, and lead, and tin, Unto the midst of a furnace--to blow on it fire, to melt it, So do I gather in Mine anger and in My fury, And I have let rest, and have melted you.
