Hi, I want to melt gold in a ceramic crucible. I was told to
glaze the crucible first with borax powder. How do I do this?
I've tried to melt some, and whatever didn't fly away formed a
burned looking lump.
Nobody ever taught me, so I may be doing it way wrong, but here’s
what I do…
First, blow air through the crucible to clear out any dust and
particles that may be sitting in there.
Then put the torch on the crucible to warm it up, not super hot or
anything, but just a minute or so on a low torch setting.
Sprinkle in the borax powder. Because the crucible is hot, the borax
should melt some and stick.
You can now put the torch onto the borax until it melts. Putting
some silver into the crucible may help a bit, since you can direct
the flame onto the metal, and the heat will conduct through the metal
into the crucible rather than depending on the direct flame of the
Again, there may be a proper way of doing this, I just happened on
this by trial and error, and I’m unschooled.
