Black Corporation: Joseon
Chapter 449
“What is this?”
Sejong, holding the pencil Hyang had presented through a court lady, asked with a face full of curiosity.
“It’s a writing tool made using ink stone.”
“Ink stone? Wasn’t that only used as a lubricant after being ground into powder?”
At Sejong’s question, Hyang answered with a smile.
“It’s a material with many uses.”
***
When graphite was first discovered, the first thing Hyang had to do was name it.
“The ‘yeon’ in graphite is the ‘yeon’ (鉛) for lead, but if we include lead in the name now, no one will understand, right?”
