This is an age old trick when you want to solder a ring, but you are not sure the stones will take the heat.
This ring was bought into me to be re-sized. So Having cut the shank, reduced it down 2 sizes, I am ready to solder. The gemstones are suspect and I don't think they will take the heat (1,000 deg c ish). So I grab a lid and fill it with water. Ideally this should be metal (mine is plastic as it was all I had to hand. Obviously if you are not carful, plastic and 1,000 deg don't get on too well. LOL
So the gemstones were immersed into the water using tweezers and the ring was fluxed. Thewater will naturally draw heat away from the ring, so a large and very localized flame is used to do this solder as quickly as possible.
The water will get warm (40deg c) whilst you do the job, but it ensures that the gemstones are not affected by the immense heat required to do the solder job.
Now all you have to do is file, sand and polish.
