Ok thanks for your input it's really appreciated.

When you say I can use metho for titration - do you mean metholated spirits or methanol?? Excuse my ignorance. I'm hoping to do a test batch this weekend.

I have sourced KOH from bunnnings 500grams for $6. How do I find out what purity it is??

Also another question -

How important is it to heat the oil for the reaction. As I understand it the mix should be heated to around 55degC and no hotter than about 60degC (as the methanol boils at 64deg).

Does everyone here heat the oil for their bio reactions?

How long does the mix need to be heated and mixed before settling?

I've nearly got all the info I need to start making some batches - just need a little help from people here in the know.

Thanks again.
