Amazing pottery! Looks like it's very durable. I love how the blending of colors on the surface that was made most probably during the 7 day period of burning it in an oven. Indeed it's a unique way of making these pots. I'm sure the potter is someone who is truly a professional and a talented one. I salute to you sir ! You are one of a kind!
