How Caustic is Wood Ash?
Wood ash is highly caustic, with a pH level of 10 to 12, making it corrosive to skin and lung tissue when not handled properly. The caustic nature of wood ash is due to its high content of calcium, magnesium, and potassium, which can cause irreversible damage to skin and eyes if proper precautions are not taken.
Understanding Wood Ash Causticity
Wood ash is a byproduct of burning wood, and its causticity is a result of the chemical reaction that occurs when the wood is burned. The ash contains alkaline substances that can cause severe burns and respiratory problems if inhaled.
