A 7th generation Onggi pottery operated by the Kim family and lead by Kim Il-Maan, a Korean National Cultural Treasure, filmed by Adam Field who was apprenticed there for most of 2008
This is the first stage, though if you were watching closely you will have seen this in the background of the previous film.
Glazing big pots, hard physical work but they are very efficient.
These films were uploaded to youtube by Adam Field, this is him making a pot start to finish timelapse, a fun film. I really appreciate him putting this material in the public domain. I also really like his pots.
