I found my mother's old Farm Master pasteurizer in storage. It is pretty old. I remember her using it when I was young and it was a used one my father had bought on an auction. I tried finding info on the internet with no luck. Does anyone know how to use this thing. It is a 300 watt, 60 cycle pasteurizer with one knob. Do I need to test run it to find the right temp setting (what is the correct temp?). She has a little mark of nail polish about 3/4 of the way on. I am trading eggs for fresh milk and would like to pasteurize it. Now I just need to convince her to give up her Dazey butter churn! Any help is appreciated.
