History of the curling iron. Is there a really thing or is the curling iron just a modern invention? Each generation is the same. We think we have invented something new when perhaps all we now have done is to modify "old inventions" by employing modern technology. Let us will investigate the history with the curling iron or, as it is also known, the curling tong.
Let us begin with the definition of an curling iron. It is a tool, a cylindrical metal appliance, used to change the structure with the hair by applying heat for a lock of hair that's curled around it. It's natural to think using a modern mind and assume that the heat is generated just by electricity. However, the curling iron goes way back before the introduction of electricity.
We just look at carvings from the ancient world to see that people cared about the type of their hair and that a popular style involved constructing curls. Babylonian and Assyrian men dyed their hair and square beards black together with crimped and curled them with curling irons. Local nobles also curled their hair and beards, in many cases staining them.
Silk nobles, men and women, cropped their hair tight but later, for coolness and cleanliness in their hot climate, shaved their own heads. On ceremonial instances, for protection from the sun, they wore wigs. The wigs may be short and curly or long and filled with curls or braids. The Science Museum has an example of curling tongs used by rich Egyptians to arrange their wigs.
In classical Greece it is known that the upper classes used curling irons.
Through time there are many methods devised to curl hair and also to keep the curl available. For example, in 1906 Charles M. Nessler, a German hairdresser working in London, applied a borax paste and curled hair with an iron to produce the main permanent waves. This pricey process took twelve a long time. Eight years later, Eugene Sutter adapted the tactic by creating a clothes dryer containing twenty heaters to do the trick of waving more properly. Sutter was followed just by Gaston Boudou, who modified Sutter's dryer and invented an automatic roller. By 1920, Rambaud, a Paris beautician, had perfected a pc of curling and drying out permed hair for more pliable, looser curls by utilizing an electric hot-air dryer, an innovation with the period made by the Racine Universal Motor Company of Racine, Wisconsin. An important breakthrough came in 1945, when French chemist Eugene Schueller involving L'Oré al laboratories combined this action of thioglycolic acid with hydrogen peroxide to provide the first cold long term wave, which was cheaper and faster than the earlier hot processes. To control the quantity of curl, varying diameter of rods were raised for rolling. Technology to hold hair in position was advanced in 1960 as soon as L'Oré al laboratories introduced a polymer hair spray to serve for an invisible net.
The curling iron has remained a favoured tool in spite of all the chemical pioneer technology. We have moved on from the metal rods heated as a result of insertion into hot coals and heating on gas and also electric stoves. jose eber flat iron
