G5193–ὑάλινος–hualinos

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;

ὑαλίνη, hu'alinē “of glass,”

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.
