Bizen ware variation

Gomma	“gomma”―the ash of the pine wood fuel files through the kiln, lands on the pots and is melted by the high temperature. It looks very much like sprinkled sesame seeds and is therefore called “gomma” which means sesame seeds. Gomma is most frequently and abundantly found on pots near the firemouth and where the flames flow that carry the most ash. When the gomma drips it is called “tamadare” or “dripping ball”.
Sangiri	“sangiri”―occurs most frequently in pieces on the floor buried in ash where flame and air do not pass through. This “reduction” effect produces blue and grey colors.
Botamochi	“botamochi”― a spot of different color in various shapes may be seen where a flattened price of high refractory clay is placed against, or laid on a pot.
Hidasuki	“hidasuki”― rice straw softened by pounding is wrapped around a pot producing streaks in various red and red oranges where the straw and pot touch.
Aobizen(Blue Bizen)	Blue Bizen is an unusual effect produced by gas clouding around a piece in the kiln.
Fuseyaki	“fuseyaki”―when two pots are stacked one on top of another a different color appears where one covers another. For example, if a sake cup is placed upside down over the mouth of a sake bottle, the inside of the sake cup and lip and neck of the sake bottle will be a different color.
