The chemical equation for the flame test for borax is: Na2B4O7·10H2O (borax) + heat → Na2O (sodium oxide) + B2O3 (boron trioxide) + H2O (water) + light emissions (color changes in flame)
Alkynes do not produce a specific color in a flame test. Unlike some other elements and compounds which give characteristic flame colors, alkynes do not exhibit a noticeable color when subjected to a flame test.
Potassium has a violet color in the flame test.
Helium does not burn in a flame test because it is an inert gas and does not react with the flame to produce a characteristic color.
If you open the valve on the bunsen burner fully the flame becomes virtually invisible and therefore there are no interactions between the original flame colour and the colour produced by the chemical.
The flame color of boron in the flame test is bright green.
The flame color of boron in the flame test is bright green.

Sodium ions give a bright yellow flame color during a flame test.
The flame test for nickel produces a blue-green color flame.
Iron (III) chloride does not produce a distinct color flame during a flame test. This compound is typically used more for other chemical tests rather than flame tests for cation identification.
The color of lithium in the flame test is red.
Silver does not produce a distinctive color in a flame test. It does not exhibit a characteristic flame color like other elements when heated in a flame.
yellow Any color in solution; the flame test is for metals.
Rhodium does not produce a distinctive color in a flame test.
Strontium burns with a bright red color in a flame test.
