I’ve been wanting to do it for years and have seen it discussed here a few times, but I finally made a candle from the wax left over after winterizing crude. Following the directions from a candle-maker friend, I heated the wax to over 100C for 25 minutes, and I’m going to let it cure for a week.
I’m thinking next time I might add the wax to a beaker of boiling water, then let it cool and skim it off the top before heating it again to remove any residual moisture. I’m thinking that might help with the color since the boiling water should in theory grab some of the pigmentation.
I’ve done this for nearly two years straight on a chem tech, which I guess is technically a roller, with no adverse results. I can probably dig up pictures of the final result too if interested. Once upon a time, to avoid using excess ethanol during winterization, we would distill twice, winterize, then distill thrice more.
Additionally, dha and epa are distilled on wfes and both are fatty acids.
Edit: I guess the question then remains, what is your feedstock from BHO or EtOH? If it’s BHO sugar isn’t going to be an issue. If it’s EtOh, then I have no clue because I did my experiment sets on BHO derived waxes.
I used to distill before winterizing, but I’m preferring the results from my methanol SOP now. Didn’t know if distilling the waxes by themselves would be much different than a crude process.
