What is the weight of cast precious metals (sterling silver, 18k

gold, 10k gold) per x volume? In other words, how do I determine the

amount of metal in a piece if I only know the volume of the object?

Use the volume, in cubic centimeters, and multiply it by the

specific gravity (density) of the metal. You can find that on any

number of charts in books discussing casting, since as it happens,

most casting wax has an SG or about 1 (same as water), meaning it’s

weight in grams is also it’s volume in cubic centimeters. So your

conversion from volume is the same as it would be if you had the

weight in grams, of a wax model to be cast.
