That is not true. You can't scrap it away. The alloy is mixed into the melted gold.
We only melt 14k (.585) with other 14k gold together. Do not mix 18 (.750) and 14 together. You will screw up thing up. We do not work with 10K, so I can't tell you anything about it. My father is a jeweler. I work for him for many years in my youth. Why do you want to melt it? the thin gold leaf will melt in a heart beat and it will end up in tiny, little BBs unless you have lots to melt.
Craig,
I take it to an assayer if you have a lot of gold to melt. He can give it back to you in its pure form, 24k, .999. Half and ounce isn't that much. If you were here, I do it for you.
