COLORS Help Scientists with Their Work!

Scientists may use a "flame test" to determine which metal ions are present in a sample of material. The color that the flame turns when exposed to the material tells scientists which metal ions are present.

Remember—fire is dangerous!
This type of test must only be done in a laboratory with adult supervision!
