I hope this is the right place to ask, my question relates to the melting points of different metals and how they react. Sterling silver is anything that is up to 95% silver and the rest copper. Both of these metals have a melt rate that is roughly 200F different. (copper 1,984F and silver 1,763)

Using gas powered kilns is difficult to control and manage temperatures with, but newer electric models can be dialed into a relatively close amount. Could you separate silver from copper by melting it off the object by steadying the temperature around 1,800F? How would a metal like copper react if it was within 180 degrees of it's melting point? Essentially I want to avoid using nitric acid and all that other shit
