Hi guys,

Does anyone have experience of using firestain free silver, in any form of it? (I understand there are quite a few different types of fire free alloy available..)
I am trying to find a casting co that uses it - if anyone has any advice or experience on this, that would be really appreciated.
I just had a batch of fire free silver back from a casting co and it was covered in that dreaded purple stain before I even got any heat near it myself - must have been from the casting process...Am I expecting too much??? I didn't think it should have firestain on it, if that's what it's meant to be free of???

Help!

Lucy
