Graphite has already been used 6000 years ago. Back then it was used to paint pottery. Then there was of course the famous deposit of graphite in Cumbria, discovered in the 16th century…
…but did you know that there is graphite on the moon?
Some of the samples brought back from the Apollo 17 mission in 1972 contained graphite!
The Moon festival is just over. Good to know that Chang’e and YuTu, her rabbit, won’t get bored up there. They can build themselves a pencil and doodle.
I found this information while trying to find out more about the Apollo L mechanical pencil.
