I have a question regarding the whole oil extraction thing.
While I've never tried the home oven method (and don't plan on it), the dish washer method or the hot water method, I have tried a different method on all the balls I currently own and have only got a slight amount of oil out of each. By a "slight amount", I'm mean the balls have a little oil sheen to them. No oil dripping off them like I hear and read about.
The method I use is a blanket warmer. If you've ever had surgery, or been in the hospital and they bring you a warm blanket, it came out of a blanket warmer. I do building maintenance at a hospital and work a weekend rotation, so I go to an empty nursing unit, empty out the blanket warmer and stick the balls in. I set the thermostat at 140 degrees (and these are calibrated thermostats) and walk away, checking and rotating the balls every couple of hours during the 8 hour shift. And like I said, only a very slight amount of oil comes out. And in case you're wondering, (or if this makes a difference), the warmer I use is a very small, countertop unit; just big enough to get two balls in. It's not one of the big, free-standing, multi-shelf units.
Since 140 degrees is about the max temp you want to use, why am I not getting more oil out? Is 8 hours long enough?
Thanks!
