Here are a couple pics of my pre and post demeth samples using the WBD as discussed here; http://biodiesel.infopop.cc/eve/forums/a/tpc/f/719605551/m/989100721/p/6
The one on the left is the pre, you can see its slightly clearer than the post but they still have not settled yet...

OK, its Done! Here is the phlip results after over 2 weeks of settling... Mind my crappy photography! Laughing

The one on the left is the pre recovery and the one on the right is the post recovery, in all the pictures. you can also tell the pre by the extra glycerin and soap in the bottom. The black hair sticking up in the pre is actually a fly's leg that drowned at week one Smile

it gives you an idea how much settled in the second week!
It appears that the glycerin is the last to fall out as you can see the thin layer on top of the soap in both batches, more so in the pre...

Conclusion;
It looks good to me! I see no visual difference in either test (other than the pre top layer in the test is not as clear as the post, likely still some methanol left?)... Do you?
I had a hard time getting a good shot of the tests thats why I only posted the one shot of them... It was the only one worth posting Embarassed
