Hauser & Miller Comparative Weights

The specific gravity of a metal or alloy is merely the weight in grams of one cubic centimeter. When it is more convenient to work in troy weights, the number of ounces per cubic inch of any metal or alloy may be found by multiplying its specific gravity by the constant 0.52686. For example, the specific gravity of 14K yellow gold is 13.07. Multiply this by 0.52686 = 6.88606 which is its

Specific gravity test for gold Goldbay

30/09/2020· The simplest way to test specific gravity is weigh the quartz gold specimen in “air” and multiply the weight by 1.9. Then weigh the quartz gold specimen fully submerged in “distilled water” and multiply that weight by 3.1. Minus the wet figure from the dry figure and you will get a fairly accurate specific gravity for that specimen!! You can then approximate how much pure gold is in
