Chun Clay Body Test Pass

Recommended Posts

 I finally got a nice lizzella clay body for chun blue glaze to pass the Recipie is 40 T-6 kaolin and 20% lizzella clay 17.32 Custer feldspar, and 27% flint and .50% black iron oxide  very fine iron oxide  not the granular material . also i prepare the lizzella clay by washing it at 100 mesh and leaving all the sand out , the iron goes up a bit to just shy of 6% iron  the test pot was fired in my small reduction test kiln for 11 hr from start to finish cone 8 reduction  but used full oxidation up to cone 06  and it vitrified, and had not so much as one bloat or pinhole  and it seems to magnify the chun glaze
