It is important to be conscious that the ceramic material is extremely fragile. Washing it in the dishwasher could cause the blades to fracture. However, ceramic knives are dishwasher-safe since heat and water cannot cause damage to the knives. They may be damaged if knives are struck or bounce against other objects inside the dishwasher.

Boiling the product over 6 hours with soda ash

– Leave one lemon slice on the surface overnight

The test fails at the point that the coating on a piece of ceramic starts to peel off. While the ceramic is damaged, replicas or copies of the ceramic should not be near dishwashers.

How Can I Ensure That My Pottery Won’t Get Damaged In The Dishwasher?

To ensure that the dishwasher doesn’t damage your ceramic, avoid placing unglazed pottery in the dishwasher since it could cause significant damage to the piece.
