What is a poddha pot?

This is a cast iron poddha pot. I asked the same question you're asking: What's a poddha pot?

It was designed for burning tall pillar candles and incense. The round bottom efficiently burns the entire candle, and the legs keep the table cool.

Consumers report using it to hold silverware at the table, or keep sauces and gravies hot.

Of course having legs, you couldn't preheat it on the stove, and it would be awkward in the oven.

Might be useful while camping, though.
