Hello Everyone - I just completed an unsuccessful casting. I
was using plastic as my model and allowed for an extra 1.5 hours
in the burnout cycle. The casting was incomplete and the silver
did not enter all the areas of the cavity. Many of the portions
that did fill appear to be pitted (ash residue?) and some of the
cannels look to partially blocked. The design was "filigree like"
with many fine lines, round and about the size of a quarter.
I was using a hand held “Castex” Steam caster. I used three 14
guage wax wires for the sprues leading to the single main sprue
that fed the casting. It looked rather like a pitch fork. I did
not attempt to blow out any ash as was suggested in an earier
Does anyone out there have any ideas as to what I could do
differently next time?
Thanks - Steve Wiser
