Phosphor

Flame spreader for one of my large center draft lamps came in. This thing looks new old stock cuz there aren't any wear marks and the brass is still shiny. The old one is missing the spreader ring. The lamp functioned ok but produced very smelly exhaust.

These lamps seem like crude instruments from the 1800s, but there's actually some impressive engineering behind the components. Flame spreaders are designed to regulate airflow to the wick and burn off unspent fuel. After warm-up, the lamps produce virtually no odor. The central tube draws fresh air from the bottom of the lamp, which keeps the fuel in the font from overheating.

The result is a nice cozy tabletop fireplace
