Turns out infrared thermometers don't get the temperature of water right.
Alerted to this when dying a shirt.
IR thermometer said 85°C - while I wondered why the water was gently bubbling.
Digging out a mercury thermometer revealed why - it was at simmering at 100°C.The shirt still seems to have dyed okay.
Any physicist care to explain?
