jcandleattic you make a good point and i have often wondered about weather it only measures surface or internal and the effect of soaping. i'm assuming for candle making temp is important tooo(don't do candles, my friend is looking into and she said she may get an infared therm.).
they advertise those themometers on soapmaking equip. sites, so i thought they might be good, so how much difference would the top of my oils and lye be compared to in the middle?
you don't use temps good for you, i'm gonna have to read your posts on those secrets.
thanks
