History The discovery of Iron

History The discovery of Iron 
BC. 
Greek nation knows about 400SM irons in use for folding, oversized clothes spruce that will be used for certain ceremonies and rituals. 
Roman nation. know the name of this board PRELUM which type of system uses pressure (pressing) are similar with wine maker / wine. 
the Chinese also know about 1SM century where the shape is still a metal pot that where in it can be filled with hot coals / coal. 
Entering AD. 
-behavior 17th century also known as "Sadiron" shaped thick metal irons heated with coals given and given the iron grip already begun. 
-akhir 19th century and early 20th century found printed board (chas iron) 
-about the 1800s found that gas electric iron commonly called iron gas and then electric iron. 
basically the inventor of ancient iron can not be determined 
must be because there is no historical evidence of the fittest could explain it. 
but many who believe and assume that that find him is Henry W Seely in 1882. 
as for the discovery still has shortcomings such tough irons hot and too fast / easy cool. 
therefore many scientists that appear to enhance Henry.dan board of scientists, among others; 
1.Cromton and colleagues who work in the company of General electrick pada1892. 
2.Earl Richardson and Joseph in 1926. 
after that many scientists who renew and menyempurnakn form of electric irons until now. 
electric irons at this time are very simple, powerful, easy to use and the results are neat board. 
As for the working system of electric iron that is: when the iron wires connected to the power source. then an electric current through the wires to the element where the element converts electrical energy into heat and heat will generate energy or base metals to iron and heat during the polymer or fiber cloth will be straight when we rub into clothes irons. the thermostat or thermostat heat we can determine that we want according to the type of clothing that we wish to setrika.dimana current regulator which has many automatic temperature. making it easier for us to iron clothes.
