The Birth of Graphite: The "graphite pencil stick" at this time is still in its original stage of merely writing.
Stage 1
The Birth of Graphite: The "graphite pencil stick" at this time is still in its original stage of merely writing.
In 1564, a place called Barlowale in England, people found a black mineral - graphite. Soon, some local shepherds found that they could paint on the sheep with graphite. Inspired by this, people cut pieces of graphite into strips to write and paint. However, graphite strips can easily stain hands and break easily. In 1761, the German chemist Faber solved the problem: he grinds the graphite ores into a powder, rinsing the impurities with water to obtain pure graphite powder, and then adding sulfur, antimony, rosin and the like to the graphite powder Material; and then the mixture is heated and solidified, and pressed into a pen shape, which is the earliest prototype pencil.
Stage 2
The birth of wooden pen pole:
After a hundred years of development, the "pencil" at this time has entered its initial stage of evolution. The appearance of a wooden pencil rod has become a "pencil" semi-finished product. The pencil rod is mainly used in the market, and users need to cut it again System can use
From today's point of view, Comte's "pencil" is actually just a pencil lead. The task of putting a pencil "jacket" on a pencil lead was completed by a carpenter named William Monroe in 1812. Monroe invented the machine to cut standardized parquet 5 to 18 cm long and to dig a groove in the middle of the parquet just for the pencil lead. The pencil lead into the slot, then the two wood on the tight, bonding, which made the first modern sense of the pencil rod. Until today, this is still the standard process for making normal pencils.
Stage 3
With the birth of the pencil with a pencil: With the extensive use of the pencil, a series of problems of the traditional pencil rod are also exposed, giving people a lot of troubles, such as: the use of unsanitary, easily broken pen, easy to carry, etc., to the pencil industry The progress of development has brought new challenges, and the emergence of a pencil with a pencil to solve the modern pencil industry product innovation encountered in the development of bottlenecks.
