In fact, some older folks in the ChaoShan area in China still boil water with a setup like this. What's really interesting is the fuel they use for the stove. The tweets you see in the above picture is just there to help start the fire. The real fuel is this:
If you don't recognize them, they are charcoal made from the pit of olives found in south eastern part of China. Because these pits have nuts inside, which carry oil substance, they give out an unique light aroma when burned. Through the air permissible bottom of the clay pot, the aroma finds its way into the water, giving the water the abiilty to enhance the Hui Gan (回甘= Return of sweetness) of the tea. These olive charcoal also burn very slowly.
Photos are taken by my friend who is also the artist still making stoves like this.
