When sourcing lamp oil, the primary focus should be on purity and safety. You must verify the Flash Point, which should ideally be above 60°C (140°F) to ensure it is classified as combustible rather than flammable for safer storage. Additionally, prioritize Paraffin-based oils (liquid paraffin) over kerosene-based alternatives, as they offer a smokeless and odorless burn, which is essential for indoor use and high-end hospitality environments. Ensure the viscosity is compatible with standard cotton or fiberglass wicks to prevent clogging.
