Limited Iridescent Collection

No two iridescent vases will ever be the same. The process of injecting a special vegetable oil mix into the hot kiln during the iridescent firing means that we have no way to control the exact outcome. Many consider the Iridescent glaze to be Pewabic's most important contribution to ceramic art. Through trial, error, and sheer persistence, Mary Chase Perry Stratton developed her first successful Iridescent glaze in 1906. Establishing the formula and stabilizing the firing process took another three years.
Today our Iridescent pieces are fired somewhat similarly, though with safer materials. It requires a third firing and a process called fuming–– when vegetable oil is injected into the kiln to create the extraordinary one-of-a-kind effects.
Note: Flower food should not be put in the water of your iridescent vessel as it will react with the glaze surface.
