Opening the Clay the Plain Way I Trust
Okay. Your clay's centered. That's the last eight lessons. Now we're going to open it up, which just means we're going to make the hole that turns a lump into a bowl.
There's a moment three weeks into learning this where the wobble just stops. I remember mine specifically. I was alone in the studio, it was late, and the clay went still under my hands and I said "oh my heck" out loud to nobody. Nobody was there to hear it. That bugged me more than it should have. You want somebody there for that one, and usually there isn't, so I'm telling you now: it's going to happen when you're by yourself, probably, and it's still worth saying out loud.
Opening comes right after that stillness. Don't wait around once you've got it. Centered clay doesn't stay perfectly centered forever, it starts drifting the second the wheel keeps spinning, so you center, you open, you move.
The method I actually use
I'll say up front, there's a technique some people swear by called a magic ring, where you sort of pinch a ring shape into the top of the clay first. I've tried it maybe five times over the last while and it has never once worked for me. I'm not going to teach you something I can't do myself. So here's the plain way, the one I trust, the one that's never let me down.
1. Wheel up to speed, hands wet. Wetter than feels reasonable, honestly. I run wetter than a lot of instructors teach it, that's just my preference, but dry hands drag and tear at this stage and you don't need that fight on top of everything else.
2. Find the center of the clay with your thumbs. Both thumbs together, braced, elbows down against your hips the way we practiced. You're looking for the middle of the mound, which if you centered correctly is also the middle of the wheel.
3. Press straight down. Not in, down. This is the part people mess up. They start curving their thumbs sideways too early like they're already making the bowl shape. Don't. Straight down first, slow, steady pressure, till you're about a half inch from the bat. Not all the way through — we'll deal with the floor of the piece another time, but for now, leave yourself a base.
4. Pull outward from the bottom of that hole, not the top. Once you've got your depth, widen it by pressing outward low, near the bottom, and let that motion travel up the wall as the opening widens. If you push out from partway up the hole instead of the bottom, you'll get an uneven floor, thick on one side, thin on the other, and it'll show later when you trim it.
5. Check your floor thickness with a fingernail or a tool, gently. Poke straight down, feel where the bottom is. You want it consistent. I once trimmed a bowl so thin I put a hole straight through the bottom with the trimming tool. Sat there and just looked at it for a second. Then I cut the whole thing in half to see what the wall actually looked like inside, since at that point you might as well learn something from it. Point is, thickness problems don't announce themselves until later, so check now while you can still fix it.
The opinion part
Everybody wants to skip this and get to the bowl shape. I get it, the bowl's the fun part. But centering and opening are the whole game. The bowl part is genuinely easy once you've done this right. If you rush the opening because you want to see a bowl show up faster, you'll spend twice as long fighting a piece that was never going to hold together, and I'd rather you spend a whole class here than take home something that wobbles.
A real caution
Keep your fingers and thumbs moving slow and deliberate near the bat as you get close to the bottom of the hole. That trimming tool story I told you happened during finishing, not opening, but the same idea applies here — going in too fast or too curious near the base is how you either punch through the bottom or catch a nail wrong. Slow hands, steady pressure, no sudden moves.
If it collapses
It will, probably today. That's fine. Scrape it, rewedge it, recenter it, try again. Nobody gets a clean opening the first several times. That's not a pep talk, that's just how the hands learn this. Your head can understand every step I just wrote and your hands still won't listen for a while.
Before next time: get one hole opened and one floor checked for thickness, even if the rest of it falls apart around it. That's the only goal.
