Before, I would use xylene to pull yellow evaporated spice,
Usually after I'd already pulled wirh naphtha to get the FB.
Even with what I consider high heat (160) and using a 85/15 mix of
Xylene and naphtha. My first pulls came out clear. I was
skeptical there was anything in the solvent at all. But upon
slow evap large round white and pale yellow crystals formed, the white
And yellow being separated natuarlly during evap.
Even now, using xylene only I'm getting the same results.
Why? Why are the yellow oils not being pulled so much?
