I’ve made quite a few plates in my time. I use a handbuilding technique where I take an existing plate and use it as a form for my own plate.
What you do is grab some newspaper, tear it into strips, and lay it on the plate form (eating side is up, as it would be in use). Spray it to wet the paper. Then lay your slab of clay on to the plate and trim it a bit. Smooth the edges.
You can decorate the clay when it is wet, you can wait until it is greenware dry, or you can bisque fire the new plate and then decorate it. In this case I used stenciling with underglazes and scratching into the clay while the clay was still wet.
Why do you need the strips of paper? So that when the clay dries, and shrinks as it does so, it will not pull itself apart and crack trying to release itself from where it has stuck on to the plate form.
You peel the paper strips off if you like, from the bottom of the new plate, before it is fired, but you don’t have to – they will just burn off in the kiln.
After the new plate was bisque fired, I then dipped it into clear glaze and fired it again. Now, anything that a person might use for food needs to have a glaze. In the case of this plate, I would say a person could utilize it for bread or unpeeled fruit or the like. And don’t put it in the dishwasher or microwave.
But it won’t hold up to heavy use – it is earthenware, or low-fire, clay that I have used here. If you want to eat off a plate as a regular dish, you need to use stoneware clay and fire to a higher temperature to get a good vitrified surface.
Anyway, here is the plate. You may see that when I trimmed the plate as described above, my hand did its usual thing and went wild of the mark. Therefore this place is out of round. Oh well. We all have our quirks.
And some closer views of the decor.
