One of the very best ways to check your work, to make sure that it's ready to be finished, patinated, stones set, or whatever the next step is - is to photograph it. Even if you've examined it wearing a visor. The lid of this canister has already been repaired and refired once! I took photos of it only to see which stone I liked best so I could made and attach a bezel. And look what I found! A tiny rip in the seam just below and to the left of the top surface. See it? Sigh.
