G5193–ὑάλινος–hualinos

And before the high seat there was, as it seemed, a clear sea of glass; and in the middle of the high seat, and round about it, four beasts full of eyes round about.

ὑαλίνη, hu'alinē “of glass,”

And I saw a sea which seemed like glass mixed with fire; and those who had overcome the beast and his image and the number of his name, were in their places by the sea of glass, with God's instruments of music in their hands.
