Red gold solder

Hi every body, I need advise on preparing low melting red gold solder
for fillings work of 21K & 22 K gold. Many thanks for any

Nasser, I just wanted to give alittle advice from my own experience.
First of all I looked for along time for a pink, red, or rose gold
solder. I still haven’t found a good one yet. As far as soldering,
high karat gold, 21 & 22k, it aint easy, its more like welding than
soldering. My advice would be to talk to someone at one of your gold
suppliers. I got a solder out of New Jersey that was supposed to be
"the," rose solder, and I’ll tell you it aint all that! Good luck!
