For making a mold to reproduce a wax, I use a number of 2 part
’impression’ materials, some I’ve gotten from my dentist, another is
available from Swest 1800 527 5057 called Quick-Sil…RTV jewelry
molding rubber. It can be used just like vulcanizing mold making,in a
frame, or as I do alot, just mix some up in hands and push in wax you
want to copy parts of. Sometime, when hurried, I just mold front of
ring to copy and add shank when refining details to wax model.
