We test new clays regularly and there is nothing so special about that. But clay I used for this teapot can be labeled as fully natural. It was picked by our friend near her house, when some workers were making trench for water pipe. Yes, she is potter and living in village which is known for traditional ceramic, she is always looking around for local clays.
Few months back, she give me backet of rough material to try. After soaking in water, sieving, drying and a lot of kneading I got few kilos of a bit too sandy, yet nice clay. Few tests later I created several teapots and some cups to see how they will stand the fire. On pictures here you can see first of those teapots. It was fired by one of our students in our small wood kiln last weekend. I am happy about the final result. And I was even more happy that Michal Zajacek of Harmony of Tea was present during unloading of that kiln. As photographer he is professional and his passion for tea is very live. What a combination! Thank you Michal.
This unglazed teapot can hold 120ml. I put some dry horsetail weed on the top before firing- it created the green-yellow ring on the lid. The clay reminds me some shigaraki pieces I saw. I hope to get more of it soon. I am quite curious how it will work with tea and how it is going to age.
