Given this experimental data, Rutherford naturally considered a planetary-model atom, the Rutherford model of 1911 â electrons orbiting a solar nucleus â however, said planetary-model atom has a technical difficulty.
1 Goldâs melting point is at about 1,943 degrees Fahrenheit, which means you will need temperatures that hot to melt it. 2  Thus, it's very important that you don't just choose any container. 3  In addition to a crucible, you will need a pair of tongs to move the crucible and hold it.
Sterling Silver melts at 1650 F, about 100 degrees less that pure silver because it is an alloy of 92.5% silver. You are not likely to use pure silver because it is too soft. Generally you melt your metal in a crucible, usually in an oven(not yout home oven, one made for casting), although a mega torch can do it.terling Silver melts at 1650 F, about 100 degrees less that pure silver because it is an alloy of 92.5% silver.
