'Glass' in the Bible

Gold and glass cannot be compared with it, and its substitution [cannot be] an ornament of refined gold.

And before the throne [was something] like a sea of glass, like crystal, and in the midst of the throne and around the throne [were] four living creatures full of eyes in front and in back.

And I saw [something] like a sea of glass mixed with fire, and those who had conquered the beast and his image and the number of his name were standing by the glassy sea, holding harps from God.

And the material of its wall [is] jasper, and the city [is] pure gold, similar in appearance to pure glass.

And the twelve gates [are] twelve pearls, each one of the gates was from a single pearl. And the street of the city [is] pure gold, like transparent glass.
