Today in class we filtered the vegetable oil using paint strainers into buckets. We did that more than once. We also heated up the clean oil on hot plates to remove water. However, when it came time to transfer the beakers to the back corner; the beaker slipped and broke. It would probably be a lot better to an ove glove to transfer the beakers safely because you can get a better grip on the slippery beakers.
What worked
The oil was a lot cleaner than before because of the filtering. I think we should wait after the oil is heated up to let the denser substances settle (water). Then we can try to separate them and filter again.
Tomorrow I think we should skim and check how clean the beakers are with clean oil. If the oil has other substances the bio diesel won't turn out right and could also clog fuel lines.
