What kind of color are you looking for? If you would like to have
exact then I whould like to have an exact question.Yellow
is not just yellow.You could have all kinds of yellow starting from
pale yellow and ending as orange yellow. Let me know !! About the
procedure,well I’m sure that many goldsmiths have their own
procedure.Some of them like to melt the gold first,then copper and as
last the silver.Other ones change the position of the copper and
silver.I’ve read lot’s of books and the majority of them mentioned
this procedure. 1.Make sure that “ALL” metals are pure. 2.Start with a
clean and prepared crucible (glazed with borax). 3.Cut your metals
into small pieces or make your one grains. 4.Fill your crucible with
the silver and copper mixed grains. 5.Cover the mix generous with
borax. 6.Lay your gold on top of this mix and preheat your crucible
from the outside. 7.Then point your flame towards the metal and heat
up the gold untill firescale appears. 8.Cover the gold with borax and
melt it with a nice reducing flame moving it gently all over the
gold. 9.Examine how the gold melts absorbing the copper and silver.
10.Keep on going untill all metals are melted into a nice mercury
like blub.DO NOT OVERHEAT THE MELT.Stire the melt gently with a
graphite or quartz rod to come up with an homogeneous not color
banded alloy. 11.Let it cool down an quench when the red color is
gone,or poor it into an ingot for further procedure.
For your health an safety, DO NOT BEND OVER THE MELT during the
proces but take a seat and sit next to it watching it from the side.
Use Eye goggles and don’t pretend like you can handle this without
them.Your eye’s (or anybody’s eye’s)are to perfect and to valuable
and can not be replaced.
One good replace the borax with sucker and powdered glass buth the
borax is really not that expensive.
Enjoy what you’re doing and lot’s of succes.
