The coated end of a match, known as the match “head”, consists of a bead of active ingredients and binder; often colored for easier inspection.
What are tips of matches?
Depending on the match type, the tips can contain potassium chlorate, potassium dichromate, sulfur, and phosphorus sesquisulfide. Friction and the resulting chemical reaction are responsible for the flame. Strike-anywhere matches contain all the necessary reactive chemicals on the tip of the wood stick.
What is at the end of a match?
Most often, it is a small piece of wood, or hardened paper. At one end, the match is coated with a material that will ignite from friction. The lighting end of a match is known as the match “head”. It either contains phosphorus or phosphorus sesquisulfide as the active ingredient and gelatin as a binder.
What is the striking strip on a matchbox called?
That source of ignition comes from the striking surface, which is deposited on the side of the matchbox or on the back cover of the matchbook. The finned strips of cardboard used to make the matches in match books are called a comb.

What is a safety match?
Definition of safety match : a match capable of being struck and ignited only on a specially prepared friction surface.
What are matches coated with?
Modern safety matches usually have antimony sulfide, oxidizing agents such as potassium chlorate, and sulfur or charcoal in the heads, and red phosphorus in the striking surface. Nonsafety matches usually have phosphorus sesquisulfide in the heads.
What is the tip of a match made from?
The head of safety matches are made of an oxidizing agent such as potassium chlorate, mixed with sulfur, fillers and glass powder. The side of the box contains red phosphorus, binder and powdered glass.
What is the red bit at the end of a match?
The heads of these matches contain only sulfur, potassium chlorate, fillers and glass powder. When you strike the match on the special surface on the side of the box, however, the heat of friction converts a small amount of the red phosphorous in the surface to white phosphorous, which spontaneously ignites.
What is the red stuff on a match called?
Surprisingly, the first chemical to react is not on the match, it is on the box! This chemical is called “red phosphorus”.
How do you strike a match without a matchbox?
Using a similar surface to a matchbox is one of the best methods, so using sandpaper or an abrasive stone is a great alternative striking surface. If that’s the case, using a fingernail or other matches (as long as they’re dry) will get the job done.
Can match heads be used as gunpowder?
Match heads contain around 40% KClO3, striking pads contain around 30% red phosphorus. When combined they make a rather potent and stable fast burning mix for small firecrackers.
Is it possible to light a match on stubble?
Though largely in countries where consumer protection is not yet well-developed. With sufficient energy, you can still ignite a safety match without the striking strip. But you’ll need more energy than the friction of scratching it on a wall or bit of stubble. (PS Don’t play with fire.
What happens when you inhale match smoke?
Also inhaling smoke fro the matches is harmful for health. One of the toxic effects with large ingestions of matches is hemolysis, which is a breakdown of the red blood cells. This causes a decreased ability to transport oxygen around the body. In addition to respiratory failure, damage to kidneys and liver can occur.
What if my dog ate matches?
Matches are dangerous to pets, as they contain hazardous chemicals such as potassium nitrate, which is an oxidizing agent. When ingested, pets can develop gastrointestinal issues like vomiting, a painful abdomen, and bloody diarrhea.

The difference between safety matches and normal matches The only difference between safety matches and strike-anywhere matches is that the match head of the latter contains red phosphorus as well as an oxidising agent and sulphur. This allows it to ignite on any surface when friction creates heat.
Why are strike anywhere matches illegal?
Turns out, FedEx and UPS both list strike anywhere matches under their “dangerous goods” lists and charge hazmat shipping fees to ship them. So, at least one brand of strike anywhere matches was indeed discontinued due to expensive shipping fees.

A chemical including red phosphorus and antimony sulfide is applied on the side of the matchbox. A chemical including potassium chlorate and glass powder is applied on the head of the match splint.
What are white phosphorus matches?
Once the white phosphorus ignites, it causes potassium chlorate, KClO3, in the match-head to burn, producing molecular oxygen, which further feeds the combustion reaction, until the wooden stick starts to burn.Phosphorus.
