Description

A high-iron slip glaze that is black with delicate brown streaks. Hare's fur is a type of oil spot effects where very hire firing temperatures allow the 'oil spots' to run down as streaks on the side of the pot. Oil spot glazes are created by first applying 2-3 coats of a high iron slip clay coated with a tenmoku cover glaze. At high temperatures (approximately cone 7) the ferric iron (Fe2O3) thermally reduces to ferrous iron (FeO) and release oxygen bubbles that rise to the surface producing a rough black spot.
