I made these using traditional hand building techniques and three types of local clay. The pot bodies are made of gray backswamp clay collected from the Arkansas River floodplain and tempered with burned and ground mussel shell. The red and white slip clays came from older upland clay deposits. The dark brown color is from ground iron/manganese pellets - sometimes referred to as the "buckshot" in buckshot clay. I fired these in an open fire using driftwood for fuel.
