I have seen some about cutting amber on various lists
and forums I frequent for cutting stones. it seems the general
thoughts on amber, are just cut it with regular wet/dry sandpaper. if
the stone needs to be dopped, regular white school glue is a good
choice, because amber is so heat sensitive. Just a soak in water will
disolve the glue. do NOT use any organic solvents with amber
though... no alcohol, acetone.... anything like that that is often
used while working on stones. solvents will distroy the amber.
