Crystalline Prussian Peacock Blue on Apple Green Orange Gradient with Black Cup #7657

This crystalline cup was made by us in our own studio. All of our pieces are hand thrown on the potter’s wheel. No two pieces are exactly alike in form, and the crystal formations can never be duplicated. Therefore, each piece is truly one-of-a-kind.

Crystalline glazes are different than most glazes in that the pattern you see on them is created from zinc silicate crystals, similar to the naturally occurring mineral called willemite. These crystals literally grow in the glaze, but only with careful attention to glaze application, glaze composition, and a very controlled firing process. Because this technique requires precise conditions, it has a very high failure rate.

Approximately 4" tall, 3 1/2" diameter at the rim.
The inside is glazed with a completely food safe plain black glaze. The bottom has been ground flat to a smooth finish.

This is made from pure porcelain. The clay is fully vitrified, so it will not absorb any liquids. Our pieces are fired to 2345 degrees Fahrenheit (high fire cone 10) and cooled in a specific process to grow crystals. The glaze chemical composition is formulated by us.

All of our pieces are waterproof, lead free, microwave safe, dishwasher safe, and freezer safe unless otherwise noted. The colors will never fade. The bottom of the mug is signed by the artist, Pam.
