Cone 9 porcelain in an electric kiln.
The blues on the left to the center vase are GCF brushed on with 3% cobalt for a rich almost toxic looking blue. A safe glaze composing of Frit 3110, Titanium Dioxide, Silica, and Zinc Oxide.
The cup on the right is Ayumi Base F matte glaze using Cobalt, stiffening the glaze with a dry texture unlike the copper version that appears more silky.
