Why is zen porcelain "premium"? The world's best refined and natural minerals: Clay and bone ash. Zen premium porcelain is made at high temperatures with a mixture of pure and high -quality ingredients. The strength and integrity of our ceramic is due to our effort to use only first -class raw materials and to thoroughly heat them in a two -stage firing process. This ensures maximum strength, durability and lightness. In addition, our products remain thin and have long -lasting colors.
