I love terra cotta pendants.
The first one is slightly dished out.
Don't think it shows much in the photo.
I used black underglaze at the leather hard state to make the decoration, then fired it to bisque.
I didn't want to put a glaze on the finished piece, but did use liquid tile finish, which is a product for sealing terra cotta floor tiles.
The second pendant is sealed with the same thing.
Both are not that big--the black and tan is about 1 3/4 inches across; the second is about 2 1/2 inches long.
