All pottery is dishwasher and microwave safe unless noted otherwise! Pottery with white gold or gold luster should be hand-washed to preserve the shine! It also should not be placed in the microwave as it is technically a precious metal. Pottery with matte decals require a little more caution than glossy. To preserve the vibrancy, matte decals should never be scrubbed with an abrasive surface. Always soak first then wipe away for grime. Glossy decal pots are nearly indestructible! You can scrub and never have to worry about color fade!
