Smelting gold together

[SteveLAO]

9ct indicates that there are 9 parts fine gold in 24 parts of alloy. or 9/24ths pure.

In modern terms 9ct is displayed as the number 375 which is called the millesimal fineness, meaning 375 parts per thousand of fine gold in the alloy, or 37.5% pure gold

So if you have 14g of 9ct gold then there is 5.25g of fine gold and 8.75g of "other metals" to make up the alloy (0.375 x 14 = 5.25)
