A single chamber wood fired kiln that was built in Japan at a workshop which I led there in 2006. It is designed to be used for the youhen charcoal finishing process, and you can see the charcoal ports in the wall in the front. It shares a large chimney with a large 5 chamber noborigama (seen behind it). It is fired on a 3 day cycle to 1250 C and then all the ware is buried in wood charcoal for the cooling cycle. This process is heavily used in Bizen. The dubbed this kiln the "Johngama" ( ã‚¸ãƒ§ãƒ³çª¯ã€€ï¼‰ .
