A couple of blog posts ago I described communion cups used centuries ago and British Unitarian churches. Some were decidedly not of a typical chalice shape. I think the tumbler (beaker) shape deserves consideration.
Flexibility has benefits. A Christian minister might have to bring his or her own communion wear. But the affordable pieces are often shabby and a good stuff is extraordinary really expensive. The unreasonable choices a minister might make have led me to an unexpected suggestion.
- Communion ware should be affordable (though not necessarily cheap) and easy to maintain.
- Congruent in form with established practice.
I think I have something: a Japanese titanium tumbler. This one is from Horie.
You'll excuse that it's marketed for beer. It's attractive, easy to keep clean, doesn't have a metallic smell and is not commonly seen in the United States, so easy to distinguish for sacred service. It weighs next to nothing and is terribly strong; you don't get both (or sometimes either) with pewter, which was formerly my favorite material for communion ware. It's not tiny -- a problem with "chapel sized" communion chalices -- and you could even go a size down.
Downsides: they're hard to get, and there's no plate or basin to go with it. A rectangular wooden tray, perhaps of laminated wood, might do the trick.
I considered this question with individual cups several years ago.
