I had to think about that too, but I think he means silver coverings that sometimes go on hands, trunk, ears etc, as part of the decorating. Many temples have gold-plated entire coverings they use on special occasions, That was my guess, but Jai will let us know.
Right, that's it. The silver coverings for the hands etc. I guess I didn't fully explain that it was for dressing and decorating the idol after the abhishekam. Ordinarily there are two priests, but this time the other one disappeared for some reason (but came back later). He couldn't reach the decorations and clothing without having to climb in and out of the shrine, so he needed someone to hand them to him. I definitely got the prasad.
