Each piece is coated with a water-based wax sealer which repels water, but does not make it waterproof. Each piece is made with artist grade permanent pigments and are lightfast and highly concentrated.
I make each piece in small batches. If you are purchasing multiple pieces in the same color there could be a variation in the color. The nature of the material and finish can also have slight variations in color, making each item unique.
Each piece is individually hand poured/handmade. Characteristics such as air bubbles, slight unevenness and bumps can and do occur, particularly on the underside during the process making them.
