URL, I thought of another solution for door plates that would not
require Brasso! The door push plates could be ceramic and have a
copper matt glaze on them. Hahah!. Sounds like a new business for
someone. ;-)

Url, the report I hear said that bronze also leaches
beneficial copper. It might be easier to keep looking nice. Being a
Vet, you are certainly familiar with Brasso. :-) I have noticed
that at my doctor's office, that their emesis basin is bronze or
brass. I always wondered why they didn't use stainless or plastic,
but this research explains why it might be preferred.
Copper in glazes was originally singled out in green lead
glazes, where the presence of copper helped leach lead. An
"unscientific" process has somehow transfered this over to all copper
glazes.
I have made dog water bowls for some time. I am thinking
that it might be good from a health standpoint, to create a liner glaze
for these bowls with standing water, with copper in it to help keep
bacteria at bay.

perhaps even with a fiercer life
because of our quiet." -- W. B. Yeats
