Watch the color of the reaction. If it doesn't turn black the reaction has not progressed far enough. When mixing, mine turns kinda golden brown, then as the Glycerol comes out of suspension it turns black. If it is a complete reaction you should see it turn a dark black. I've had a similar problem before and just added KOH in 1/2 lb increment's till it "turned". The problem seems to be suspended water. It removes some of the KOH from the methoxide and stops the reaction.

Hey Phil, since you have it running right now anyway, how about if you pull a 1 cup or so sample, and see if any glycerin settles out of it. It should take less than 10-15 minutes for that to happen. If you get any separation that's a good sign. You can just dump it back into the processor one way or the other. Just a thought if you have the chance.

ahhh were on to something guys. long story short my old mans sick so i decided to set this up at home (im 21yr ol) to be with him more on the weekends. right now i have the kitchen counter covered with 3/27 tests and cups full of water trying to get everyting the same temp LOL.
black as black can be. and it seperates QUICK. within 5 min a "ball" gar is septerated. i think im good to go. let glycerin settle and drain?

alright well i could wait any longer and put 10gal of hot water in to wash it down to see if that could make a difference. i took an educated guess and figured it was high glycern (soap) floating in there. i have no idea why. i did everything step by step. i took a sample and heated it up and the bio was super clear...however its not that cold here..40's
heres my step by step process one again. if anyone sees a problem in this can they please let me know
1. transfer cheese cloth-ed oil into processor tank
2. heat to 140
3. add koh and methanol
4. mix for 1.5 hours.
5. 3/27 test to check completion of process
6. once passes or dark glycern quickly settles to sample container let glycern settle and drain
7. move to wash container
8. add app. magnesol and mix for 30 min
9. let settle over night.
there are the EXACT steps i am doing. no other this and that added in here and there. is this ok?

Magnesol will remove ALL the crap including methanol. If you don't remove the methanol first you need 2% magnesol. I use a weight of 7.5 lbs/gallon as the weight of a gallon of biodiesel. As an example: 10 gallons of bio = 75 pounds which would require 1.5 lbs Magnesol.
