Hi Gaylen, I teach classes in fabrication, and I have the beginners
use paste flux, easy and medium solders only (I have them wait until
they’re better at soldering before messing with hard solder), and I
strongly stress cleanliness of metal surfaces and seams that are as
perfect as possible. Paying attention to these little things really
makes soldering easier and the soldered join stronger, which in turn
makes subsequent operations easier. Making a bezel is usually one of
the first steps in making something, but if your bezel seam breaks
later on when you’re setting the stone, it can really be a disaster.
It’s not possible to tell you how your torch flame should look
without knowing what kind of torch and fuel you have.
