Found a purpose for the hand building class‘ bottle project!
this is naked b mix, sanbao underglaze sheet w some black speedball underglaze freehand with a wide-nib fountain pen, under studio satin clear. Top is just painted w studio black-grey slip, definitely more of a slate dark grey w bluish tones. But I’m happy :)
@Peter Lee I just used an old calligraphy nib on a fountain pen, dipped it into speedball underglaze. I think it’s too thick to flow from a cartridge
