Does any know how heat tolerant Tiger eye is? Can I solder with it
in place using precautions? I need to enlarge a ring with a piece
of tiger eye glued in, don't know if I can remove it successfully.
(its kind of the old "we had to destroy the village to save it"
If it’s glued in, gentle heating will loosen it. If epoxy, the glue
tends to expand and bubble up slightly, almost lifting the stone out.
Easy in most cases. This suggests that you shouldn’t be expecting the
stone setting to remain intact even if tigereye could take heat.
If you can keep the whole thing cool enough around the stone such
that the glue is not damaged, then the tigereye will be fine too.
However, more than that gentle heating will cause tigereye to change
color. The commonly seen yellow/brown tigereye colors turn to
brownish reds. Kind of pretty, and sometimes you see heat treated red
tigereye for sale for exactly that reason. But if you don’t want that
color change, you can’t allow the tigereye to get all that hot.
Again, however, in your case, the glue and it’s lower temperature
tolerance, is likely your limiting factor.
