Bought a coffee boiler what is it?

I have giant pot that holds nothing but water. Blue enamel with the white speckles. Not real sure of the capacity, but I'd say like yours something like 12 cups. Bring it to a boil, slowly stir in 1-1/2 cups of ground coffee.........say Folgers regular, being careful, cause sometimes this will foam up over the top. Turn the heat way down and let it go for 6-8 minutes. Take it off the heat and serve it with a little wire had held strainer to catch the mud as you pour a tasty cup
