Types Of Matches
Friction Matches
John Walker, English chemist who in 1826 discovered first “friction match”. He combined mixture of sulfur and other materials that were coated on the wooden stick, and rugged paper that was coated with phosphorus. By running the match between folded paper, sulfur would ignite and set the stick on fire. He managed to sell numerous matches of this design during the next few years, but it became apparent that his chemical formula was not suited for widespread use
Noiseless Matches Janos Irinyi 1836
Janos Irinyi (1817-1895) was a Hungarian chemist and inventor of the noiseless and non-explosive match. He achieved this by mixing the phosphorus with lead dioxide instead of the potassium chlorate used previously.
Charles Sauria, chemist who first managed to introduce mix white phosphorus in the match industry. Even though his mixture created during 1830s was incredibly potent and easy to ignite (even self-ignite), toxicity of white phosphorus caused outrage of people and government officials, who after several decade of use declared it banned.
Present
Creator of the most popular match design in the word is Swede Gustaf Erik Pasch (1788–1862), who with Johan Edvard Lundström managed to form the “safety math” – easy to use, cheap, and non-toxic match that did not have capability of self-igniting. By putting the phosphorus coating on separated location, small matches with their now famous red heads became instant hit all around the world.
Johan Edvard and his younger brother Carl Frans Lundström (1823–1917) started a large-scale match industry in Jönköping, Sweden around 1847, but the improved safety match was not introduced until around 1850–55. . In 1858, their company produced around 12 million matchboxes.

Zaysan
Lakes 20.9 % Earths Water
Lake Zaysan
Lake Zaysan is about 40 million years older and is believed to have formed sometime during the Cretaceous period (145 – 66 million years ago). Lake Zaysan’s old age is widely accepted but determining the lake’s exact age has been difficult – it may be even older than 65 million years.
Lake Zaysan is located in Kazakhstan near several artificial reservoirs and the Bukhtarma dam. The construction of the dam caused Lake Zaysan to rise above its natural level by about 6 m (20 ft). This increased Lake Zaysan’s total area and in some sources the lake is listed as part of the artificial reservoirs.
