The safety match was invented in 1844 by the Swede Gustaf Erik Pasch and improved by John Edvard Lundström a decade later.

Their safety is due to the separation of the combustible ingredients between the match head and a special striking surface, and the replacement of white phosphorus with red phosphorus. The striking surface is composed of powdered glass and red phosphorus, and the match head was composed of antimony(III) sulfide and potassium chlorate. The act of striking converts some of the red phosphorus to white by friction heat. The small amount of white phosphorus then ignites, and this starts the combustion of the match head.

The two Lundstrom brothers had obtained a sample of red phosphorus from Arthur Albright at The Great Exhibition, held at The Crystal Palace in 1851, and made safety matches with it. They misplaced the matches and did not try them until just before the Paris Exhibition of 1855. They were still usable.

The Swedes long held a virtual world-wide monopoly on safety matches, with the industry mainly situated in Jönköping. They sold their French safety match Patent to Coigent père & Fils of Lyon, but Coigent contested the payment in the French courts, on the basis that the invention was known in Vienna before the Lundström brothers patented it. The British match manufacturer Bryant and May visited Jönköping in 1858 to try to obtain a supply of safety matches but were unsuccessful. In 1862 they set up their own factory and bought the rights for the British safety match Patent from the Lundström brothers.

Safety matches are classed as Dangerous goods, U.N. 1994, and are not forbidden on aircraft, but must be declared as Dangerous Goods.

Oh grief... I haven't heard about "safety matches" for years. They are matches, usually something like kitchen matches, but they come in books too... and they are matches that have a structure such that they can't accidentaly be struck one against the other and light. You have to take one and deliberately strike it on a rough surface.

I can remember book matches when I was very young and you could get them all to light by hitting the book cover in the right place.

i do no longer think that an purpose default place exists. many kinds of gods strike me as absurd. i'm maximum in all probability confident that the universe should not be under the control of an entity that behaves like a defective individual -- a bad tempered new child; or a psychopath; or petty minded power freak. concept in such monsters looks to require a sort of neurosis. A writer God this is basically benevolent, yet helps finished freedom to all helpful factors of the production -- alongside with unfastened will to human beings:- with the aid of default I regard that as non existent. plausible, yet no longer likely. I acquire the probability that private experience ought to steer everyone to handle the life of such an entity because of the fact the default. Universe as God: pantheism or comparable. I regard this as completely feasable. If I ever come to the tip that the finished is unsleeping, then i could stop calling myself an atheist. I have not have been given any default concept right here, so I oftentimes call myself a pantheist, generally an atheist.
