All you need is a suitable metal salt and a fuel: Strontium or lithium salt. Clean-burning fuel. Strontium and lithium salts produce red flames. Strontium, in the form of strontium nitrate or strontium chloride, yields the red color seen in emergency flares and red fireworks. Lithium chloride produces a vivid reddish-violet or pink flame.
Mixtures of metal/nonmetal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures of a nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979 p. 108-109]. Special Hazards of Combustion Products: Yields toxic gaseous oxides of nitrogen when involved in fire.
Strontium nitrate's chemical name is strontium nitrate, or Sr (NO3)2. The substance strontium dinitrate is a white, crystalline solid. Although it is a fireproof substance, it improves the burning of substances that are. If an excessive amount of nitrate de strontium is involved in the fire, it may explode.
The carbonates become more stable to heat as you go down the Group. The effect of heat on the Group 2 nitrates. All the nitrates in this Group undergo thermal decomposition to give the metal oxide, nitrogen dioxide and oxygen. The nitrates are white solids, and the oxides produced are also white solids. Brown nitrogen dioxide gas is given off ...

Strontium nitrate has the chemical formula Sr(NO3)2 S r ( N O 3) 2. It is a white crystalline solid at room temperature. It dissolves well in water and alcohol. It is hygroscopic, meaning it absorbs moisture from the air. Strontium nitrate has various applications. It acts as a source of strontium in making alloys and other compounds.
Squeeze the cup so that a crease is formed in the side. Pour into plugged tubes, leave empty space of maybe 1/8". Insert pieces of bare match and allow to dry until there is no odor of solvent – this may take 2 – 3 days. To test, simply tape the go getters to a bottle rocket stick, or a 6" pice of small dowel.

Strontium Nitrate Steel Sparklers. Grind unground components (if any) separately. Mix together all your sparklers components except dextrin. Add 25 ml of 25% aqueous ethanol (25% alcohol, 75% water) to dextrin and stir until it becomes a paste. Break up or discard any large clumps that form in your sparklers paste.
