I have been lurking for a little while enjoying the posts and info
and have been looking thorugh that archives for any info on the
problem I’m having. I am very new to jewelery making so please
forgive me if I am missing the obvious.
I am having trouble with my hard solder leaving a brassy sort of
line on the seam. I am using a propane sievert torch, pripps flux to
prevent firestain and a borax flux paste applied to the seam I wish
to solder. The solder is flowing beautifully and there aren’t any
apparent issues with the solder pitting. I am pickling in a safety
pickle and neutralizing the piece in bicarb of soda. The line where
the seam is just shows as a very thin line of a sort of brassy
colour, not likethe more pinkish shade of firestain. Once the piece
is finished, as it starts to tarnish, this line becomes more
pronounced and very obvious. I have tried different solders from
different sources in case I had got muddled up but I am having the
same results with all which means the problem is most definitely me.
I am sorry if this is one of those newbie questions that has been
addressed before but I have tried searching in the archives but I
cannot seem to find anything directly relating to this.
I would be extremely greatful if anyone could help me to understand
where I am going wrong.
