The next technique that we're going to talk about is spiral wedging. The first one we did was called Rams Head. And that's a very direct technique. And that works great for smaller amounts of clay, I'd say anywhere up to four to six pounds, we'll say three to four pounds, the Rams Head works great, you start getting four to six 810 12 pounds. This power wedding is going to work a little bit better for you because it's going to break the clay down into two sections, so you're not necessarily handling the entire amount at once. Again, we're going to use two different colors of clay body here to help illustrate how this is going to work the clay together so we can actually see the clay as it moves together.

Knock them into shape a little bit. Okay, so I'm gonna begin by rounding this edge a little bit. It now it's gonna be a little bit different than than Rams Head, my main pressure is gonna be coming from my right hand in a downward swooping motion, something like so well, I'm going to be guiding it with my left. So it's gonna be a rocking motion similar to this. You'll see what I mean here in a second how we're going to start to break this clay into two sections. Down in a way And again, it's just that short three or four inch movement, I'm going to pull it back towards me and again, down in a way down in a way, always pointing back towards you, lifting the clay up ever so slightly up on the shoulder of the point right here, not completely on the point, but roughly on the shoulder right here and move that clay down in a way down in a way.

You can see how this clay I'm going to speed up so you can illustrate the technique here. As we're moving through this. You can see how I'm actually beginning to separate the clay into two pieces here and this piece of the clay here is rotating through As soon as you move with larger and larger pieces of clay, you're not going to be attacking the entire clay at once. We're breaking it up in these sections, which makes it a little bit easier to handle. Pull it back upon a shoulder, back up on a shoulder. So it should look against something like that.

You can see how that clay starting to break up and become fully integrated in there should have a spiral motion going here on the left hand, and that's where your left hand sets guiding that clay. But again, it's that downward motion down in a way, just a slight sweeping motion. Once you get that rhythm down, you can really move through this pretty quickly. Now similar to the Rams Head technique, when you're ready to begin to finish up your form, to simply start backing off the strokes. So right now we're moving about three inches or so. I'm gonna slowly start backing it off.

Three to two inch and a half inch, half inch and we should end up with a cone shape that looks similar to that. You see there's no differential between the white and the red clay body. They're fully work together. And again, the only way to really tell how we did would be to cut this in half and check for air bubbles. So there you go, we have no air bubbles. There's very little differential if any of that white and red clay they're fully worked together fully homogenized, we have a nice even moisture content all the way through the clay body.

Clay platelets are moving through that spiral motion. We're ready to take this piece of clay and move to the wheel and get to work.
