The last step of Fushigigama has ports to introduce hardwood charcoal (not charcoal briquettes!) directly onto the load of ware. This is done at the peak of the firing just after ceasing stoking wood and just before sealing up the kiln. Here you can see the general process. -

Hardwood charcoal is introduced on top of the wares on the last step of Fushigigama once the stoking is complete...at about cone 12-13. Then the kiln is sealed up and the burning charcoal causes reduction cooling effects. The charcoal tends to pop and sizzle into sparks....which you see in this clip. -
From the album: Kilns designed/constructed by John Baymore
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" ( ジョン窯　） .© 2006 John Baymore -all rights reserved
