Tricky business, this.
Soldering a pre-assembled Byzantine chain takes rather more
precision than I can manage, so I’ve switched to the
slower-but-easier method of soldering each link as it is added. I
use cross-lock tweezers as a makeshift third hand, grasping the link
to be soldered. This worked well at keeping the soldering area away
from the rest of the chain, but the steel tweezers also acted as a
heat sink: The link got hot enough for the solder to stick and melt
somewhat, but not enough for the solder to flow well and even out.
The solder flows great when I use a charcoal block and no tweezers,
but then the previously soldered links heat up, too, and get stuck
What is the best way to deal with this? I have yellow ocher (not
sure what to mix it with, though) and could apply it to each
finished link. Or, I could put the chain on a firebrick instead of
the charcoal block.
