There's a
very large list of verbs that will work, depending upon what it is you're actually doing with the clay. The three you list are possible, but you can also:
pinch, score, flatten, join, scrape, dry, extrude, shape, form, pound, stretch, throw, join, layer, cut, heat, moisten, pull, coil, layer, poke, fire, bend, loop, flex, lean, twist, carve, fashion, pat, trim, brush, paint, stamp, and dozens if not hundreds of other verbs.
Some of those might apply only to regular clay, not oil-based modeling clay, but that should give you an idea. Just choose the most appropriate verb for the action you're doing -the fact that it's clay doesn't really limit your verbs.
I mean, I probably wouldn't '
drink' or '
eat' the clay, but you've still got plenty of other verbs to interact with.
