'Glass' in the Bible

Hast thou with him spread out the sky, which is strong, and as a molten looking glass?

For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.

But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.

For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass:

And before the throne there was a sea of glass like unto crystal: and in the midst of the throne, and round about the throne, were four beasts full of eyes before and behind.

And I saw as it were a sea of glass mingled with fire: and them that had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God.

And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass.

And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass.
