Since most placer gold is flat and thin, its weight is small relative to its circumference so it will usually float.
How do you test gold with baking soda?
Wash the stone in the baking soda/water mixture then rinse it in water and pat it with a paper towel. A reaction (dissolved line) shows that your sample has a lower purity, a slight reaction means that you’ve matched the Karat while no reaction indicates that you have a higher Karat gold.
