[KS] What is the history and use of charcoal in South Korea?

[Knigel Holmes]

Thank you all for helping me with finding out if the myth behind the
Tancheon (The Stream of Charcoal) was actual Korean folklore. I have,
unexpectedly, become obsessed with charcoal. I hadn't realised how
much charcoal was, and continues to be, used in Korean society. I've
been learning about the charcoal kiln saunas, "white charcoal',
charcoal air fresheners, and lumps of charcoal over gates to fend off
evil spirits from birthing women; however, I'm having a bit of trouble
finding out some of the other historic details in English about
charcoal. I'm wondering if any of the anthropologists, or anyone else,
could direct me to some history or folklore on charcoal in Korean
society. I'm interested in any tidbit or fascinating fact. I
appreciate your help a lot.

Kindness,
Knigel
