LEAD, Purified by fire

Numbers 31:22

22. Only the gold, and the silver, the brass, the iron, the tin, and the LEAD,

Jeremiah 6:29

29. The bellows are burned, the LEAD is consumed of the fire; the founder melteth in vain: for the wicked are not plucked away.

Ezekiel 22:18-20

18. Son of man, the house of Israel is to me become dross: all they are brass, and tin, and iron, and LEAD, in the midst of the furnace; they are even the dross of silver.

19. Therefore thus saith the Lord GOD; Because ye are all become dross, behold, therefore I will gather you into the midst of Jerusalem.

20. As they gather silver, and brass, and iron, and LEAD, and tin, into the midst of the furnace, to blow the fire upon it, to melt it; so will I gather you in mine anger and in my fury, and I will leave you there, and melt you.
