Red phosphorus: The three colors of red, yellow, and white are insoluble in organic solvents and soluble in tribromide bowls, and can fire above 200 degrees. 2. Manganese dioxide: The molecular formula is MnO2. It acts as a catalyst. The color is black and the molecular weights are 86 and 94. It is a safe drug, easy to store, mainly sealed, and placed in a dry and ventilated place. 3. Potassium chlorate: The molecular formula is KC1O4. It is a white powder or end-capped crystal, which generates heat by the reaction. It has a molecular weight of 74. It is a dangerous substance. It should be kept away from pressure and hammer and should be avoided from fire. 4. Sulfur: The molecular formula is S. It is yellow powder or lump which acts flammable. The molecular weight is 32.  It should be stored in a dry and ventilated place. 5. Rich and strong powder: It has a high viscosity and should be stored carefully. (It can be replaced by glue.) 6. Pigment: It is mainly used to adjust the colors of matches. Industrial and edible pigments are acceptable. Generally, industrial pigments are better.
