Signed and dated stoneware chalices

Here are two lovely ceramic pieces, stoneware chalices or stemmed glasses with a beautiful blue glaze. They appear to have been created in the same workshop, perhaps by two different ceramists. Indeed, the throwing technique is the same, the glaze is very similar, and the signatures are alike, though the handwriting is different; one is dated 2004 and the other 2006. They are in very good condition, with no flaws to report on one and a single original imperfection on the other: a tear in the clay on the inside only, probably caused by firing. They measure 10.5 and 11 cm in height respectively, and 7.5 and 8 cm in diameter.
