What powder is used to lift fingerprints?
Find some fine powder.
Fingerprint powder is a very fine powder that is either white or black. White powder is used to dust prints on dark surfaces, and dark powder is used if the print is left on light colored surfaces. Officials use either talcum-based powders for white, or graphite-based powders for black.

What do police use to dust for fingerprints?
Fingerprint powder is composed of many different ingredients that can vary greatly depending on the formula used. Most black fingerprint powders contain rosin, black ferric oxide and lampblack. Many also contain inorganic chemicals such as lead, mercury, cadmium, copper, silicon, titanium and bismuth.
What surfaces can fingerprints not be lifted from?
Non-porous Surfaces
These are mainly smooth surfaces of which the latent print resides on the surface. Examples of non-porous surfaces include glass, plastics, metals, and varnished wood.
How do you test a suspicious powder?
Samples of the suspicious powder are collected using two chemically treated swabs – one for a protein test and one to measure pH levels – and placed within color-coded test tubes. Each test produces a color change in the solution within five minutes if protein is present or if the sample is acidic or basic.
How can you tell if a powder is white or baking powder?
This is the simplest test. Baking powder contains an acid, so it will bubble with any liquid. Baking soda does not, which is why recipes that use it always contain an acidic ingredient (vinegar, lemon juice, buttermilk, or acidic fruits).
