Porcelain Purism Speckle Effect Unique Pieces Enjoy fine hot beverages from this teapot. The Coppa teapot by ASA impresses with its exquisite porcelain craftsmanship and thorough handwork. The so-called reactive glazes give the products a wonderful look with unique color gradients, surfaces, and other features that in no way indicate a flaw in the product, but rather make each individual piece a unique item. Various effects distinguish each piece individually. Color gradients, speckles, dots, small bubbles, and even irregularities are not grounds for complaint, but are explicitly desired by the manufacturer and contribute to the personal touch of your new dishes.
