My GoodWill Tetsubin Water Kettle Find, Unkown Artist

I was shopping at a local goodwill when I came across what appeared to be a grimy greasy cast iron tea kettle. It was heavy, but I had no clue of value other than it interested me as being an odd looking cast iron tea kettle. Since I have quite the collection of more porcelain like tea kettles at home..I thought why not pay the $5.00 price tag surely it must be worth at least this much. After bringing it home I started doing some research and learned about alot of cast iron tea kettles, and tetsubins (water kettles) the ones without the tea basket inside. I saw alot of very ornate cast iron tea kettle,of which made me think this may not have much respect in the way of value. Then up late one night I began to wipe away a bit of the grease build up, which started to show a beautiful copperish lid with this whimsical looking top. I used a gentle cleansing wipe, and coconut oil, and by the time I cleaned alway all the greasy debris. I discovered I had a very nice looking kettle. The next day I did more research upon this kettle because I was confounded by it's brownish-bronze looking color to the cast iron, and then I discovered a signature next to the spout. I learned that these kinds of kettles which had a more sanded texture were some of the earlier kinds of Japanese Cast Iron Kettles, and were a basic household staple used for heating water, and because the flavor of water in cast iron kettles were much preferred by tea drinkers. I learned they called the sanded appearance types "Hado" meaning Sanded, and that the colors that made up the bronze like composition were largely dependent on the materials used to make such cast iron kettles. I was disappointed that I couldn't find this signature anywhere and on any other kettle. Many were under lids, on the bottom or sides of kettles,ect. Some were written in squares, and others by the spouts just didn't match my symbols. Then I also learned that in the process of preparing a cast set to fire such a kettle was never intended to make multiples of the same kind of kettle, and that rather many casts could only make one or a few kettles. I am enamored with my kettle. I've tested to see if it holds water without leaks, and I found it has no leaks. I asked an oriental Japanese friend to try to interpret the symbols, and she said the bottom one appeared to represent "culture" and the top, she thought to be more representative of Chinese , and thought it meant "Kibun", which is to say emotional well being, from what I assume. She did say that her thoughts were that the symbols seemed to not be completely either Chinese or Japanese, and at some point, especially if this is an older Tetsubin due to its sanded, or hado appearance, which suggests it its. As time went on the influential people wanted their Tetsubins personalized with images of dragons, or flowers, or something more artsy. I also learned that unless the sands, and chemical compositions that made up the Cast Iron materials, had to be preserved by generations in order to replicate similar color hues that made each Tetsubin unique. The chances of that happening is unlikely. I feel very special to have found such a treasure. I realize the whimsical tops of the copper lids were usually representative of plum flowers, or persimmons, ect, but there are these peculiar cut outs in mine, three various, one reminds me of a lamb, another looks like a bannana, and the other a pear shape. I don't yet understand the meaning of these shapes, if they were ingredients used i certain tea making, or what the representative meaning is of them. Alls I know is that I found a treasure in my local good will. I also found a carved table like a tea table. I would like any input on the artist behind this kettle, and if any of the interpretations of it are correct. If incorrect, or is there more to learn from someone here more familiar with tea history and the cast iron making of tetsubins and their culture. If anyone can help me learn the language interpretation of the artists signature, and it's meaning I would be enamored. We here in America have a true appreciation for the time and mastery of making such teas. And I have a a personal interest in healing health issues, as to help my body heal through the ancient arts of natural herbs, and teas. Thanks for your assistance in educating me in your expertise. Thanks for your time. Sanday.
