Transcript Wood Vinegar Kiln

Wood Vinegar Kiln
Iwasaki Kiln
• Japanese design
• Efficient at making charcoal
and wood vinegar
Step 1
Heat enters
charcoal chamber,
becomes trapped
and circulates,
converting wood
into charcoal.
Step 2
At 80-120 degrees
Celsius, heated
wood releases
pryoligneous acid
(wood vinegar)
Step 3
Smoke/steam
enters the bamboo
chimney and
rapidly plummets
in temperature,
causing steamy
pryoligneous acid
to condense.
Step 4
Cooled
pryoligneous acid
steam condenses
into a collectable
liquid form within
condenser
