i recently bought a Chawan as a decoration piece.
At first i will admit, that i have not a single clue about Japanese pottery! So, since that was made clear... this is what the seller said about the piece:
"A real Kuro Raku Chawan, made about 30 years ago in Tottori. A nice example of Kuro Raku Pottery, with an excellent glace and a nice footing. Nice snail(?) is visible. With signature in good condition. Measurements: 12x8,5cm"
Feel free to leave a comment and it would be nice if someone is able to read the signature (if that is even possible).
