Two Charcoal furnaces can be found on the southern coast of Hosidius. Each furnace can hold up to 60 Juniper logs, which can be lit with a Tinderbox to produce Juniper charcoal. 50 Juniper charcoal is produced per log, for a total of 3,000 if a full 60 logs were added, taking approximately 16 hours. Juniper charcoal is one of the required ingredients for making Dynamite.
Smoggy, a nearby Lovakenji dwarf, must be paid a fee of 600 Coins per furnace to watch over the 16-hour burning process.
A bank chest is located just south of the furnaces.
