I stamp my bronze clay pieces BRZ - I don't know if they will put
me in the dungeon or not but that's what I do here in Canada.
Thanks Charles, that's interesting.
In Australia it's a volountary standard.
However I know of a few jewellers that have been saved from
litigation by using the standard.
Although you don't have to use the standard it's wise to do so.
