    Qwarla; In Spanish language and in English language to a lesser extent an "a" on the end of a noun, a name may indicate you are a woman rather than a fat old bearded man. Anyway photosynthesis catches energy from the sun, a nuclear explosion. Vegetable oil production from plant material is caught energy from the nuclear explosion sometimes called the sun. Using fatty acids from plants to make biodiesel does harness catching energy from a sizeable nuclear explosion (our sun).

    I have tried this mixing an entire batch of glyc to clean the next lot of oil. The result was astounding with beautiful clean oil from crap with a tiny titration. Unfortunately the glycerol thickened so as it would not drain from my heating vessel and although I managed to separate the oil and process it by taking it off the top I had to dig out the byproduct and the guy who takes my byproduct for handcleaner promised that if I ever did it again he would stop picking up my glyc.
    QED.

    yep you do have to drain it while it's hot.

    Gsmiley, were you using KOH or NaOH for the reaction that provided the byproduct?

    3DB, Hello. I have to do a 10/90 dropout (Warnqvist) test on my glyc washed oil. As I can glyc wash my oil multiple times with ex process glycerol there is always some conversion, so to calculate chemicals the dropout test needs to be done.

    The test usually shows between 10 and 25% conversion. I do a 2 stage reaction and use a total of additional methanol of between 10.5 and 13.5%

    Yep i find the same thing - if you let it sit for too long and cool then it will only just creep through a 1 inch hose to drain it - then once it is in your 25 litre drums it is a slow process to get it back out once it has set in there - but it will eventually drain out.
