Oil and Fat Lamps

Rendering animal fats and pressing plant oils for reliable lighting without electricity.

Oil and fat lamps provide low-cost lighting using locally produced fuels when electricity is unavailable.

Key Concepts

  • Fuel viscosity and wick material determine flame stability.
  • Rendered fats can fuel lamps but require filtration.
  • Lamp oxygen supply affects soot and indoor air quality.
  • Simple reflector surfaces improve useful light output.

Practical Guide

  1. 1.Render animal fat slowly and strain impurities through cloth.
  2. 2.Use clean cotton or plant-fiber wicks sized to burner opening.
  3. 3.Trim wick height to reduce smoke and maintain steady flame.
  4. 4.Ventilate enclosed spaces during prolonged lamp use.
  5. 5.Store fuel in closed, labeled containers away from cooking fires.
