The two pieces in the front of the picture at the right are the parts of a lidded casserole. This is my first attempt at one of these. (Ok, confession time: I did make one a long time ago, but it was not a good experience, so I pretend that it didn't happen.) The low flat bowl shaped thing on the left is the lid and the slightly deeper bowl shaped thing on the right is the bottom of the casserole.
Now a smart person would have checked to see if the lid fit BEFORE removing it from the bat. That way, if it is too large, it can be trimmed easily while it is still centered. I'll do that next time. (Sometimes the first time to do something new is a valuable lesson in what NOT to do.) Sure enough, the lid was too big and I had to wait until it was dry and then sand the heck out of it to make it fit. I was significantly too big, so I sanded and sanded and sanded and sanded. Then I'd check the fit and do it again. Not fun, but eventually effective.
I realize now that it would have been nice to also have a picture with the lid on. Oh well.
We shall see what happens in the following steps of firing, glazing, and firing.
