Lab: Flame Test Flashcards | Quizlet
Flame test, test used in the identifiion of certain metals. It is based on the observation that light emitted by any element gives a unique spectrum when passed through a spectroscope. When a salt of the metal is introduced into a Bunsen burner flame, the metallic ion produces characteristic color in the flame.

Overall it can be concluded that in the case of enzymic treatment and biomordant the two step process was better in terms of larger K/S values, color coordinate values, and dye adherence. It was shown that the former two give comparable results with metal mordanted samples and thus were suited for industrial silk dyeing and the range of colors are good too.
