The obvious response is wrong. Never put water on a wax fire. Each droplet of water goes instantly to steam, a 540-fold increase in volume, an explosion of steam and smoke and on the rebound flaming droplets of wax. Smother a wax fire. A CO2 extinguisher or salt or a towel controls a wax fire quickly, safely.
Liquid wax demands careful handling.
A drop of boiling water stings for a second, then cools and quits. A drop of hot wax, perhaps a hundred degrees hotter than water can get, burns and keeps on, and sticks. Wax holds a lot of heat, many calories per gram. If what gets on you is more than a drop, it can injure or disfigure. Don t be frightened, just aware of what s happening while you work.
