'Glass' in the Bible

Something like a sea of glass, similar to crystal, was also before the throne. Four living creatures covered with eyes in front and in back were in the middle and around the throne.

I also saw something like a sea of glass mixed with fire, and those who had won the victory over the beast, his image, and the number of his name, were standing on the sea of glass with harps from God.

The building material of its wall was jasper, and the city was pure gold like clear glass.

The 12 gates are 12 pearls; each individual gate was made of a single pearl. The broad street of the city was pure gold, like transparent glass.
