A friend of mine needed an urn for a pet. He had a round dome-shaped disk that he wanted to incorporate into the project. There wasn't really any way to inset the disc, so it was decided to use it to cover the opening and it will be glued into place with a silicone glue to seal it. This will hopefully allow for any slight movement of the wood. Due to the disk being used at the top, it was decided to go with a "vase" design instead of a more traditional urn design. The part where the disk will attach was only sanded to 100 grit for better adhesion. The rest was sanded to 600 grit, which is the difference in color and obviously texture at the mouth.
On a side note, I do not have a hollowing rig or really even proper tools for this type of work. At one point I had a scraper, along with most of the handle, inside the mouth while I was hanging onto the last 2" of the handle with both hands. I can describe what "chattering" is if you need me to.
