The Kutahya Porselen Reactive Glaze cups feature the innovative technology of reactive glazing, which creates unique finishes during the firing process in the kiln.

This means that the final result of each item is unpredictable, either due to oxidation or chemical reaction during baking. Each piece is distinct and one-of-a-kind.

The small imperfections that may be observed are not manufacturing defects, but rather characteristics that contribute to the uniqueness of each item. Thus, there are no two pieces of reactive glaze tableware that are exactly identical, setting them apart from mass-produced items.
