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.
Put all of the scraps of one type into the crucible, and apply a layer of baking soda over the metal. Raise the flame on the torch according to the type of metal you need to melt. Copper, brass and gold will all melt between 1700 and 2000 degrees, while iron and steel will not melt until nearly 2800 degrees. Put on gloves and apply the torch flame to the crucible and wait for the metal to melt completely into liquid.
