GoldSmith

Every day we, the Gold smiths, need to change the purity of our gold for different type of work. Some times we have to increase the gold purity and we calculate the amount of pure gold to add 'into the gold we have', Some times we have to decrease the gold purity and we calculate the amount of Alloy to add 'into the gold we have'. This app will calculate the exact amount of alloy OR gold we need to change the purity of the gold 'we already have'. Just fill the current weight of gold you have, fill current purity, and desired purity. Just one click will give you exact amount.
