Some pieces are, if you check the description on the piece there is specific care instructions. However, anything with a chain is a no. This being said, I really recommend washing all pieces by hand. These pieces are artisan, they are not as durable as factory made ceramics. I always wash my ceramics by hand to ensure longevity. Dishwashers have harsh chemicals that can break down ceramics over time, they also are powerful and have strong vibrations that can also ware down your ceramics. It’s safer to just hand wash, I know that’s not the answer people would like but it’s the way to ensure your pieces stays at their best for the longest.
