One issue is do not add the methoxide (methanol solution) to the oil if the oil is too hot, above say 60 degrees centigrade. Superheating of the methanol could occur and it might come back out of the bottle. I think glass is better to use, rather than a plastic bottle.

Does it matter if he adds the warm oil to the bottle with the methanol/KOH mixture or should it be the other way around where you add it on top of the oil?

either way works, by adding the oil to the methoxide the reaction can be faster but most of us use a process where the methoxide is added slowly to the oil.

I see by your join date you have been around for awhile. I was not trying to be alarmist in my previous post, the dangers are real!

it is now separating! Only thing is we transferred it into a glass jar. The pop bottle top started melting in the process and came off.

Don't inhale any of it. I hope you held your breath when transferring that to the glass container, especially if it was warm enough to melt plastic! The fumes are really bad news.
