Though not as definitive as the spectral fingerprints from atomic spectra, the colors produced by chemicals when inserted into a flame can be used to identify some constituents of minerals. One procedure used was to put a small amount of the chemical on a small loop of platinum wire and place it into the open flame from a laboratory burner.

You are seeing the spectrum produced by sodium ions, which is the same regardless to the source in which the ion is found. Every element has its own particular spectrum of colours that the atoms or ions will emit when energy (in this case heat) is supplied. When you heat the salt containing the sodium ions, the movement of the electrons in the energy levels of the ions cause the release of light photons with frequencies that depend only on the element involved, and not on the particular salt of which it is part. So, the sodium in sodium chloride, sodium nitrate, etc all produce the same bright yellow colour that is a characteristic of sodium. Some spectra are seen in the diagram below:

yellow-orange A typical flame will burn yellow-orange with a little bit of blue near the base of the wick. When you burned the skewer tip coated with sodium chloride, you should have seen that the flame was pure yellow-orange (without any blue). This is because when the metal sodium is burned, it makes intense yellow-orange light.
