You have probably spent your life fag under the misapprehension that allchalkis the same . Chalk — you know , the dust-covered white sticks you use to write on a chalkboard ? chalkboard — the thing they used in classroom before the 1990s to visually shew the subject affair being discussed in class ? It ’s possible you missed that particular geological period of history .
Which might be why you ’ve probably never pick up of Hagoromo Fulltouch Chalk — unless , of course of action , you ’re amathematician . blackboard have been disappearing from educational institutions for decades , but math is possibly its last stronghold . Mathematicians favour write complex theorems in chalk than with a whiteboard marker or a smartboard . And Hagoromo chalk has been account as the " Rolls - Royce of chalk . "
ground in 1932 in Nagoya , Japan , the company that became Hagoromo Bungu barely hold up WWII , but went on to produce 90 million sticks of chicken feed a yr by 1990 . By this time , mathematicians from all over the world covet the product . consort to chalk connoisseur , it ’s dense and difficult to break , produce very little dust , writes more smoothly and erases more cleanly than any other chalk in existence .
The Stockpiling Begins
After the company ’s sales peaked in 1990 , though , blackboard start go away around the globe , and with it sales of the world ’s most sought after chalk . In 2014 , Takayasu Watanabe , the head of the third - generation kinfolk business and grandson of Hagoromo ’s founder , announced he was in very piteous wellness and rather than saddle his three daughters with a flag troupe , he would just close down yield .
There was , of trend , an garboil amongst the macrocosm ’s mathematicians . Academics began stockpiling the clobber — calculating how much Hagoromo they needed to last them the remainder of their careers . mathematics professor filled home water closet with the stuff and nonsense and began selling it to each other in module lounge — these were suspenseful multiplication in the maths human beings .
But then , Shin Hyeong - seok rode in on his blanched horse and lay aside the Clarence Day — at least for the time being . A Korean schoolhouse instructor , Shin had been importing Hagoromo chalk to Korea for a ten , and approach Watanabe about buying the secret rule for Hagoromo deoxyephedrine . After some serious weighing , Watanabe give in and invest Shin the equipment to make the chalk , as well as the occult secret chalk recipe . Not only that , the very duplicate brothers who had been primarily making Watanabe ’s chalk moved to South Korea to take over Shin ’s fabrication of Hagoromo .
So the math world can heave a suspiration of relief for now . Until , of course , the universities begin submit their blackboard aside .
