Coolants - keeping gemstones cool


#1

This is an age old method of keeping gemstones cool while sizing
rings. Take a potato, yes, a fresh potato, slice off part of it to
make a flat surface on top and bottom. Leave as much potato as
possible. Cut a slit or carve a small area out, depending on size of
stone. Do this dead center so there is as much potato as possible on
sides and bottom. Bury the stone into the slit leaving only the area
to be soldered protruding. There is a great deal of water in a dense
material that will keep the stone cool. You still need precise heat.
I have soldered emerald and opal rings this way. Then you can plant
what’s left of the potato !

I wanted to thank you and it does work. I am working on some
multiple stone pendants, and at the last one I found a weak solder
joint. Tried the place it in water trick (all the gem stone parts)
and could not get enough heat to flow the solder. Went to the potato
trick and viola in seconds at was repaired. Thanks Pauline and for
those of you doubting Thomas’s it really does work!
