thanks a lot, i will get a thermometer and measure it Gesendet: Samstag, 01.

Hi All,
Typically the heat pain threshold for the fingertips is reached around 42 degree Celsius, so if it is not yet painful to touch the temperature most likely is below 42. I admit that it takes masochistic tendencies to knowingly perform such approximate heat measurements...
