For something to catch fire, three elements are required. Fuel, oxygen and heat. These must co-exist for a sufficient period of time for a fire to propagate. The absence of any of these three elements will prevent a fire occurring. Sparks are small entities that are in the process of completing the combustion process. So, when a spark flies onto your clothing it will not set fire because 1. your clothing are not sufficiently flammable (lack of fuel) and 2. there is not enough time for the spark to heat your clothing to the temperature required to ignite your clothes. However, if your clothes are doused in gasoline (or petrol) the spark will ensure a very whooof ending!! DO NOT try this at home.
Also it's important to remember the difference between heat and temperature. Each spark has quite a high temperature, but, being very small, not much heat. It therefore cools off very quickly when it hits the clothing. In fact, it will have cooled quite a lot even before hitting the clothing.

Why dont sparklers burn your clothes?
It might seem surprising, but sparklers won't usually burn your clothes since the sparks that they produce are minute and release heat quickly after they have detached from the stick. Although the sparkler is extremely hot while burning, the sparks are too brief and light to inflict any damage when they touch clothes — especially common clothing like cotton or denim. All the same, sparklers still present a threat if you don't watch your step. Some materials (silk or tulle, for instance) are more fragile and could be set on fire by the hot end of the sparkler. It's always safe, therefore, to hold sparklers at arm's length and away from garments, especially during events where people are all dressed up — like weddings, say. Here at Wedding Day Sparklers, provide the highest-quality wedding sparklers that are perfect for send-offs, photos, and providing a festive, safe atmosphere. Just be responsible in using them, and you'll get all the sparkle without the stress.
Why do people in desert countries usually wear light colored clothing and some sort of headgear?
Dark colors absorb the heat from the sun's ray and lighter colored clothing reflects the heat away. Covering the head, especially in a light color also protects the head from the heat of the sun and protects the skin from sun burn.

The reason that the white-hot sparks that strike your skin from a 4th-of-July-type sparkler don't harm you is because?
the duration of contact is very short, limiting the transfer of heat to your skin. Additionally, the sparks from sparklers don't have enough energy to cause significant harm. The sparks are also made of material that burns quickly, reducing the chance of causing a burn.
What element is used in a sparkler to make the sparkle?
A sparkler consists of several substances:An oxidizerA fuelIron, steel, aluminum, or other metal powderA combustible binderIn addition to these components, colorants and compounds to moderate the chemical reaction also may be added. Often, firework fuel is charcoal and sulfur. Sparklers simply may use the binder as the fuel. The binder is usually sugar, starch, or shellac. Potassium nitrate or potassium chlorate may be used as oxidizers. Metals are used to create the sparks. Sparkler formulae may be quite simple. For example, a sparkler may consist only of potassium perchlorate, titanium or aluminum, and dextrin.
