Even though I won’t be writing long blog posts I might still find the time to post links or write short blog posts.
I’ll start with some youtube videos. Watching it you might think it is an old recording (style, background music, quality), but it is a new episode (April 2013) from a series by NHK’s international broadcasting service.
You can find more information about the show at NHK World.
To celebrate 350 years of Bleiweißsteftmacherhandwerk the craft of making pencils – Bleiweißsteft is what the Bleistift (German for pencil) was called during the 17th century the Franconian and Bavarian regional news reported live from Staedtler’s factory on 25 September 2012. The reports were only a few minutes long.
Dr. Konstantin Czeschka, Chief Technology & Production Officer, and Axel Marx, Managing Director, talked about the history of the pencil and included these interesting details:
The graphite used for pencil leads is ground to particles whose size is in the range of a micrometer, one millionth of a metre.
In 1900 there where 23 companies manufacturing pencils in Nuremberg. They employed 10,000 employees.
One machine, shown on TV, can produce 1000 leads per minute.
The pencil leads are heated to 1000°C
The leads seem to be made in Nuremberg, but the pencils seem to be assembled in their factory in Neumarkt.
I thought Staedtler’s mechanical pencils are made there, but didn’t expect their pencils to be made there, too. I mentioned Neumarkt in a previous blog post when I wrote about the ONLINE All Wood Marone. ONLINE is based in Neumarkt, too, as is e+m Holzprodukte.
Producing a pencil is a fairly automated process. You only need about 1-2 seconds of human labour time. 100 years ago about one minute was needed, 200 years ago it was about an hour.
The price of graphite is expected to rise. One of the reasons is that it is needed for manufacturing batteries for electric cars.
