Always conduct the process outdoors or in a well-ventilated garage, away from any sources of open flame or electrical sparks. Heat the oil gradually over medium heat, stirring occasionally to ensure even temperature distribution.

Keep a metal lid or a box of baking soda nearby to smother any potential flare-ups, and never leave the oil unattended during heating. Preparing for the Boiling Process Safety is paramount when handling hot oil, as it can smoke, bubble, and pose a significant fire hazard.
The oil will darken in color, ranging from a light amber to a deep reddish-brown, indicating that the polymerization is taking place. Heat catalyzes the oxidation and polymerization of the oil’s fatty acids, creating a harder film that cures significantly faster than its raw counterpart.
