'Glass' in the Bible

and before the throne, as a glass sea, like crystal. And in the midst of the throne, and around the throne, four living creatures, full of eyes, before and behind;

And I saw as a glass sea, mingled with fire, and those that had gained the victory over the beast, and over its image, and over the number of its name, standing upon the glass sea, having harps of God.

And the building of its wall was jasper; and the city pure gold, like pure glass:

And the twelve gates, twelve pearls; each one of the gates, respectively, was of one pearl; and the street of the city pure gold, as transparent glass.
