Totally agree with cousin Petra (no we are not related).
I use a lot of fine silver. I try to limit contact to clear to Bullseye 1401 clear. That is less prone to yellowing. No problems when embedding the silver for a loop for a bail hook.
I use it also for Faux-cloisonne, but that again is only on 1401.
Keep using the fine silver. note that using sterling changes everything, so stick to fine.
