Slight Haze in Test batch

Ok I made a second test batch with new oil from Walmart

heated oil to about 120F

Added in the methoxide mixture

Agitated the mixture

Let settle for 24 hours

Have dark but very clear what I believe to be glycerin layer at bottom of bottle and a light but slightly hazy settled on top of that. Here is a photo

Smarter folks than I, any thoughts tips etc ?

Thanks

Properties on that pic were: http://www.redrocktitle.com/bio.jpg

Skip it - I rightclicked and hit "SHOW PICTURE". Yes I have dial-up....

Are glass containers available to you? That looks like a plastic bottle, metal cans may be helpful. It looks like temperature may be the issue.

*MAny service stations will give away used twenty to fifty-five gallon barrels just to be rid of them.

Thanks Ill take a look into that although I had A similar issue with the first batch but it was real clear in the mixing bottle but got slightly cloudy when I washed it.

I am thinking about running it through another heat cycle any thoughts ?

By the way the picture its small 34K I took it with the camera phone

Looks just fine to me

New oil will not have "black" colored glycerol, since it hasn't been "burned" by cooking yet. The "haze" will disappear once the bio is "washed". Looks like you made a good test batch!!

Try increasing the temp to about 140 deg also.

Is there a clothe that can serve as a strainer to help eliminate fat bleed through in the dregs? Something like a toilet paper roll oil filter? (replaceable)

Ok Cool thanks for the answers, I will start the wash tomorrow in the AM. I was running the temp a little low just due to the plastic bottle

Simplified skimming is a natural fore thought....

Some way to peal off the unwanted solids.

Ordinarily the solid fats are on the bottom. That puzzles me. What you have there is above the clear fluid.

I wonder if an aerator could be used to tumble the mixture prior to the settling out stage?
