Aug 22, 2019· 3,200 Deg F foundry temps are the goal to melt silica sand . The melting point of sand is 3,110 deg F.
To prove that there are different substances in the test tubes, two of the samples could be mixed together and the melting points tested. If the melting point is lower than the theoretical melting point, then they are two different substances. If the temperature at which the sample melts remains the same, then they are the same substance.
