How are electron excited in a flame test anylses?

In The name of God Introduction: Flame test is method to identify the element (metal ions) based on Emission spectrum. The test involve putting sample of Unknown element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which make the color back to normal. Then compare it to flame test result of former lab but after testing it with cobalt blue glass. Material: 1- Safety Goggles 2- 250 mL beaker 3- 500 mL beaker 4- Bunsen burner 5- Cobalt blue glass 6- Distilled water 7- Flame test wire 8- Dropper 9- Test plate with walls 10- Spectroscope 11- HCl solution 12- Unknown Solution Number 6 Procedure: 1- Small amount of HCl was added to small 250 mL beaker. 2- The Bunsen burner was lighted. 3- The flame test wire was dipped into the HCl for minute then heated by holding it in the Bunsen burner for another minute or until all the red color is gone. 4- The flame test wire was cooled and then rinsed with distilled water into 500 mL beaker. 5- Full drop of unknown solution # 6 was added to test plate. 6- The flame test wire was dipped into unknown # 6 Solutions. 7- Then the flame test wire was put to fire. 8- The procedure No. 3&4 were repeated to clean the flame test wire. 9- The flame test was dipped again in the Unknown solution # 6. 10- Blue Cobalt glass was used to test the color. 11- The flame test wire was put to fire while holding the blue cobalt glass.
