The glass has a purple tint to it and bubbles that I believe are indicative of the age, and original process. I have not tried to use it or to clean the brass burner piece - I'm sure it would come up beautifully if you'd prefer it to be polished. The burner hinges open as you can see in the photos and has the words QUEEN MARY on it. I can't see any damage or scratches.
