The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
The red lithium flame leads to lithium's use in flares and pyrotechnics Copper compounds glow green or blue-green in a flame. Calcium compounds glow orange in a flame. Sodium compounds glow yellow in a flame. A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color.
Lithium nitrate is an inorganic compound with the formula LiNO 3. It is the lithium salt of nitric acid (an alkali metal nitrate ). The salt is deliquescent , absorbing water to form the hydrated form, lithium nitrate trihydrate.
A variety of food colorings, added to beakers of water. Food coloring, color additive or colorant is any dye, pigment, or substance that imparts color when it is added to food or beverages. Colorants can be supplied as liquids, powders, gels, or pastes. Food coloring is commonly used in commercial products and in domestic cooking.
High-temperature flame with solid particles, which interfere with flame colorants. Reacts with nitrates, except ammonium nitrate, yielding nitrogen oxides, ammonia, and heat (the reaction is slow at room temperature but violent at above 80 °C and may spontaneously ignite); the reaction can be inhibited by a weak acid, e.g. boric acid. Corroded ...
A flame test showing the presence of lithium. Flame test of a few metal ions. A flame test involves introducing a sample of the element or compound to a hot, non-luminous flame and observing the color of the flame that results. [4]

Several of the CPK colors refer mnemonically to colors of the pure elements or notable compound. For example, hydrogen is a colorless gas, carbon as charcoal, graphite or coke is black, sulfur powder is yellow, chlorine is a greenish gas, bromine is a dark red liquid, iodine in ether is violet, amorphous phosphorus is red, rust is dark orange-red, etc.
