This is my first post, so I apologize if this is in the wrong place,
wrong format, etc. That aside, let’s start with a simple problem:
When silver soldering, sometimes I get a pit right where the solder
chip was sitting. Many times I do not… sometimes I do. It never
happens when applying solder with a pick, so I suspect it has
something to do with the solder sitting there on the hot silver for
too long. I always prepare a clean surface, use flux, heat the piece
not the solder, etc. Just wondering:
Scientifically, what causes this? It’s curious to me that the
silver sheet below the solder actually LOSES quite a bit of material
in the transaction… and forms a big ugly pit - where does it go?
How to ensure it doesn’t happen? Just use the pick? Heat the
silver more quickly? Different kind of flux?
One observation: This has happened more, recently since I got a
Smith Little Torch (oxy/pro). I have not had this problem for years
previous when chip soldering with a $12, hardware store propane/air
Thanks for any help!
