This large ramen bowl in Speckled Cobalt blue is colored with several oxides including Cobalt Oxide. This deep blue glaze is speckled - I really appreciate this speckling effect and feel that it adds so much to the final product that would be missing if the whole glaze was uniform. Its this variation in handmade pottery that I adore and hope you can appreciate too. The Volume of this bowl allows for a very generous serving of pasta or salad.
