Fineness based on corrected mass
Webretained on each sieve by the original sample mass. (3) Calculate the percent passing (or percent finer) by starting with 100 percent and subtracting the percent retained on each sieve as a cumulative procedure. For example: Total mass = 500 g . Mass retained on No. 4 sieve = 9.7 g . Mass retained on No. 10 sieve = 39.5 g . For the No.4 sieve: Various ways of expressing fineness have been used and two remain in common use: millesimal fineness expressed in units of parts per 1,000 and karats or carats used only for gold. Karats measure the parts per 24, so that 18 karat = 18 ⁄ 24 = 75% and 24 karat gold is considered 100% gold. See more The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of fine metal therein, in proportion to the total weight which includes alloying base metals and any impurities.

For … See more • Colored gold • Electrum • Gold as an investment See more Millesimal fineness is a system of denoting the purity of platinum, gold and silver alloys by parts per thousand of pure metal by mass in the alloy. For … See more The karat (US spelling, symbol K or kt) or carat (UK spelling, symbol C or ct) is a fractional measure of purity for gold alloys, in parts fine per 24 parts whole. The karat system is a standard adopted by US federal law. Mass See more Fineness of silver in Britain was traditionally expressed as the mass of silver expressed in troy ounces and pennyweights (1⁄20 troy ounce) in one See more
