I have a problem with a mans signet ring that I’m putting together. The
body of the ring is in red injection wax. The top which is approx. 2mm
thick is in green carving wax. I have put the two together and cast as one
piece, sprue being on the bottom of the shank.
I must be missing something here for I would think that red wax has a
lower melting temp. than green. But what appears to be happening is the
green wax is causing investment breakdown.
Other castings with the same batch of investment came out fine, so that
does’nt seem to be it.
The ring being cast is approx. 15 grams with no fine detail to really
I’m going to try again only this time running wires to the top portion of
the ring, hopefully this will help in drainage.
I’ve tried this once quite a while back and basicly had the same problem.
Any suggestions would be appreciated.
