Strange temperature rise

When I made my last batch of bio (250L), I did the titration and the 80/20 thing with 50L of methoxide. I agitated with 80% (40L) of methoxide for 5-6 hours, settled overnight, and drained off the glycerol, several times, until bio came out. Then started the pump, put in the 20% remaining methoxide. I forgot to switch off the pump and came back 12 hours later, and the temp in the tank was 60°C. After it cooled, it washed out looking a little like mayonnaise, but washed cleanly after settling out. However, there's sediment on the bottom of test bottles, and it's settling out quite slowly. What happened there?

Sounds like you homogonised the byproduct back into the biodiesel.
