The latter platter

The best plate so far.

So far in the drying process, it's down to just under 10 3/8" diameter.

Good shape, not too thick, and not as much damage done in trimming it. That's the pisser, that every time I trim these plates, I damage the rim. I realized that there were two sources of the damage. One is simply the fact that the plate is upside-down, resting on its rim. I prefer tilted, flat-surface rims, so the upside-down plate rests on a narrow edge at the extreme of the rim. So as I slip it into the proper position on the bat, or the Giffin Grip, the clay scrape along the surface. Even if it's leather-hard, that scraping contact is going to produce some damage. The other source of damage seems to come from using the Giffin Grip itself. The three small pads designed for gripping low items like plates amount to a very limited contact surface area, meaning more force is transferred to the points of contact, thus deforming the plate more noticeably than a wider area of contact would do. So on this trim, I went back to using lumps of clay to hold it down. I used six pieces, with a total contact area of perhaps a third of the rim circumference. While I still ended up with some damage on the topmost edge of the rim, from scraping, the outer edge is in much better shape on this one.
Live and work and learn.
