V-328 Iceberg Blue

Available from Seattle Pottery Supply when we last checked. Sold from the shop’s own store; the price there is the one that counts.

Iceberg Blue Velvet Underglaze is a light blue color that is powder blue at cone 05, slightly darker at cone 5, and maintains its light blue shade up to cone 10. A clear glaze over Iceberg Blue tends to lift the color out slightly, lightening it.
