Recently I made a trio of small boxes with driftwood handles attached via wire wrapping. The perfect size for wish boxes or jewel boxes. The dimensions are in the range of 2-1/2” more or less. The pieces were extruded from mid-fire porcelain.
At the bisqueware stage, underglazes were applied, plus a coat of clear glossy glaze. After the pottery was glaze fired, one coat or multiple coats of lusters were brushed on. Lusters contain metallic elements, to give an iridescent effect.
The mottled halo effects that appear in the top picture were made by touching and re-touching the surface with a dispersing agent using a brush point. The pieces were then refired at cone 020 (1180 F).
