"Glass? I was under the impression that the Body and Blood are to be in 24k gold, plated at least. I've seen Waterford, but I'm not sure about that. That might not be right, but that's my understanding."
Okay I think I was mistaken. The precious blood must be in a metal chalice but I have seen priests use glass pitchers from which they pour the wine into the chalice. Which seems fine because it is just wine until it is consecrated.
I think most of the pitchers are actually crystal, but probably cheap. I actually have seen Waterford used, but very rarely.
