Lighting kerosene attempts.... spark, flame, torch. All CAN light it, but how easy..? (and note a spark of an heater spark plug would be hotter and often in a steam of kerosene atomized in air. The heaters without fans always use a battery op glow wire from what Ive seen. Quartz would also usually have a hot blue spark. Our sparks can be blue too.

Also the clear kerosene burns easier than red dyed stuff IMEx. I think it soots and smells more though. Red is a "home grade". Some stations have both...point is, the grade varies.
