Charcoal

I just found out what charcoal is made of. All this while, I thought charcoal = coal, coal = charcoal. Another ignorant side of me. Only after reading an article about "Johor stops extraction of bakau from mangrove swamps" by Star Online Nation, did I realise charcoal is made of bakau wood from mangrove swamps. Learning something new every day, getting less ignorant by the day. :D
