He might want to try investing in real chalices.
That is exactly what he did after the incident:
The server of Item 1 above has gone to college. His family lived in a large and lovely new home, where I imagine they drink ice water out of crystal glasses at the oak dinner table. For him the glass chalices were just like the dinner water glasses. The padded oak chairs in our sanctuary were just like his dining room furniture.
I did not want a chalice upon ordination, thinking it would be a waste since Communion would be forever under both species and we would need sets. Thinking there is value in the visible, I used glass -- until that server and his ears. We no longer have the crystal or the ceramic set in liturgical colors, but two matching gold-colored metal chalices, and any new sanctuary chairs will be of a nobler wood and design.
When they carried it, they were required to carry it veiled, and to only touch the veil.
