Hi Brenan & Welcome to Orchid
It just so happens that where I am a guest lecturer (Cal. College of
the arts-formerly CCAC) one of the seniors has been doing this as
her main project/thesis…
What I have learned from her is:
Cut your metal up into tiny pieces…
When placing into the crucible do it in 1/3 increments…Meaning
put in the first batch, melt, add the second batch, melt and then
the last batch & melt…
Use lots of flux–borax.
It will melt longer than it takes for a bronze melt.
Set your casting machine arm/wind up for a longer spin out.
Cool down to dead cold,and then quench.
And of course, keep a separate crucible for your copper castings
and use high grade copper…
*** Your surface will be rough…We have used copper for our organic
castings & this texture issue is really a non-issue. ***
Guess you would say I’m an older pooch who is still learning new
P.S. We have even been casting aluminum, successfully…
P.P.S. Another mention of a great show that John & I are pleased to
be apart of:
