I am exceptionally shocked at how much of that was done by hand.

[@JustWasted3HoursHere]

I was going to say the same thing. Way more labor intensive than I would have guessed. But, I imagine these old ways won't be around for too much longer because of new technology both in how the chalk is made (to remain cost efficient and competitive in today's world) and in how chalk is used in schools: So many schools have gone to digital methods of displaying information to students.

[@pathemep]

@@snaplash You didn't see the rest cose it is done in anather factory. This one particular factory is possible in Japan only. Yes it is done whole process in one place only. Modern production process is spread on many stages in many different places. Cose you can use same production equipment in other purposes, not for chalk making only. You just can't build the factory for only chalk making exclusively, it is economical madness.

I love that they use chalk to make notes on the mixer. I always assumed that all chalk was calcium-carbonate. I learned that gypsum is also used here. I figured they would add dye to the calcium-carbonate, but it appears that coloured chalk is different.

[@nashvillain171]

Funny thing is that I always thought chalk was made only of gypsum! 😄 I suppose Japan, as an island nation, has an abundance of calcium carbonate sources. Where I live--inland--there is a great amount of gypsum.

[@phil6506]

LOL. I thought chalk was mined, There is after all natural chalk.

[@nashvillain171]

@@phil6506 Well, you're correct. The raw materials--whether gypsum or calcium carbonate--are indeed mined.

[@Bubu567]

@@nashvillain171 Gypsum is the 'chalk' you find in walls, but calcium carbonate is the natural chalk you find in nature. It has a silkier feel when used, while gypsum has a sharper, squeekier feel. Ideally, the best chalk would be a mix of the two, to balance softness and hardness.

Respect to these workers. Amazing how much goes into making chalk.

[@jcmartinez7527]

The reason a lot of schools switched to Expo markers and whiteboards was because of fear that the chalk dust would be damaging to computers. I still prefer chalk but its rarer and rarer to find. At my university, only the math building kept blackboards. Presumably because of the math professors preferring chalk.

[@heiseili9279]

Also a nightmare for kids allergic to it. Was happy as hell when digital boards came to my school.

[@andrewzwaniga2016]

I’ve studied at three universities so far and in every math department there is a legend about chalks imported from Japan. There is a particular brand that went out of business, I recognize it by the box but not by it’s name. Legend says that you cannot write a false theorem with it. (It is beautiful, exquisite chalk, writes very smoothly and almost never breaks.)

I wonder if there's a noticeable texture difference between the Calcium Carbonate and the Gypsum, other than just color? It seems like it would be neat to test! Thanks for sharing! This was awesome

[@stompyrobutts]

Carbonate chalk tends to be more durable, less dusty, but skips, produces skinnierer and less contrasted lines than calcium sulphate chalk, or gypsum chalk. Sulphate chalk, being less durable and dustier, produces excellent broad and well contrasting lines. But you will burn through miles of it on a blackboard. The holy grail was the Hagoromo Fulltouch Chalk, which had the properties of sulphate chalk, with an added wax layer to keep the dust down, with a carbonate formulation producing durable and long lasting chalk. But they stopped production in 2015 and has recently been sighted at over $800 a box. A korean company bought up their equipment but apparently its just not the same.
