I am trying to make a cold connection (heating the metal to create a
ball) with 14ky using semi precious beads. First I tried top drilled
teardrop garnet, then moonstone roundelles, then round garnet beads.
Not all on one piece, but testing each one. However each stone
shattered or split down an inclusion. I checked them under 10x and
didn’t see any inclusions, but I guess there were some. I am using
propane for soldering/heating. Does anyone have any suggestions?
