I’m sitting here with my wife, on our 11th Anniversary, toasting to the new year with some sparkling apple-peach cider in our Waterford Crystal toasting flutes and guess what I see?
The inside of the Waterford Crystal glass appears to be a perfect parabola! Crimey! I’m trying to figure out how to pour molten metal into a crystal glass to make a reflector! It’s an addiction I tell ya, pure and simple! And y’all started that reflector craze right here, in this very thread! 
Happy New Year!
