 What I'm going to make is I'm going to make a large plate with the rib. I've made a small plate. People have seen it in a learning size. The DVD on here before is a beginner-sized piece of clay. And the rib has a lot more uses than just a beginner-sized piece of clay. Once you get a hold of the rib, you can learn how to throw very large pieces. So right now I'm flattening this out to be a plate. So a plate is just a short, fat cylinder. So in order to get a short fat cylinder, I have to throw a short pancake to make it out of it. And it's always difficult to center the outside rib. This part's always very wiggly and hard to center and you can spend time fighting with it or not. I like just to give it to the size I want and then as the wheel spins I hold my needle still. And of course the needle goes down with the spinning wheel and it's round. It's not cheating, it's my plate. It's my plate and then I have someone to keep my needle. So after you've done that now you've got a nice, nice pancake in which you can pull your plate out. I'm going to open this at about a 45 degree angle going down. I think sure you go down as far as you want for the bottom. So once you have it open it's more difficult to make it thinner. And I'm going to open with my left hand and I'm going to pull the clay across with my left hand. But as I pull it across, this clay here wants to peel off. So I keep it in check with my thumb and then my right hand goes over top and they pull it across. And clay has a speed where it wants to open. I'm letting it open quite slowly. A number of revolutions of the wheel are happening before I make distance across the bottom of the plate. And all the time I'm keeping it in check with my thumb here and my right hand there. And we just pull it across, not allowing that to peel. Now as you get close to the edge, to the outside edge, you can move your thumb that was supporting here to the supporting that way. So your hand is squeezing together and your left hand is supporting. Pulling across at the speed that feels comfortable with your foot. And after you've moved across a few times you'll know what I mean. And all the time keeping it connected as it goes across and working my thumb this way to make sure it stays connected and my right hand is working to make sure all these pieces stay together and never peel. Sometimes it's a peeling. So I pull it across, keeping all those edges blended as well as you can. I've got to cross about as much as I want to before I start opening up the other way. So at this point I'm going to clean out the inside bottom of it. There's some thickness there. I'm going to get rid of it just by peeling it off, going from outside in. And then I'm going to level it across that radius. So before I go any further I want to compact this bottom. So what I'm going to do is I'm going to work back and forth along this radius, one leveling it and two compacting all the particles. And I like to go past center and then back again. Just to give your bottom a workout. And now I'm going to start throwing the walls. I'm going to continue pulling my inside hand across and my outside hand is going to go up a bit. I'm going to get some height there. Again, making sure these edges stay compacted because you're bringing the two sides together. And as you pull up, keep it cone shaped. You keep the top tilted in, it will plate and bowl out when you tell it to. And not when it chooses to be a fairly large plate. I'm going to make sure I maintain this edge to be fairly thick. Because when I open this plate it's going to open up at least twice the size. And so twice the size is going to be half the thickness. So if you start out with a thin edge, by the time you have your plate open you're going to have a very thin rimmed plate. And the plate of this size deserves a nice thick rim. It has to be a plate of substance. So what I'm going to do with this roof, this is where the roof comes in now. It has a nice little curve to it. I'm going to take it down this side and I'm going to blend with this edge the wall of the plate into the foot of the plate so I don't have a square thing happening. And I like this, you can hang on to it whatever is comfortable. My elbows are on my knees, my elbows into my rib cage. And I'm going to bring it down, and I'm not going to go straight down, I'm going to bring it down and tip the toe toward my tummy. If you don't do that it wants to chatter. It wants to go like this. Once you've got it going on the merry-go-round it's very difficult to stop it. So now I'm going to open this up. Now I've got a nice join for my wall to my bottom. It's going to, with a 45 degree angle, open this plate up. As you see, the rib enables you to throw a very large piece. I'm going to tidy this up. The clay out here is very open. The particles are a slight open because I threw it very quickly. So I want to give it one throw to compact them. And I'm going to compact the rim. But notice this rim is still a nice thick rim because I started off with it some thick. You couldn't have a plate this size and have a little wussy rim. So I'm just going to compact that, smooth it out. Now I'm going to tidy up the bottom a bit more. And I like, again it's personal, but I like the throwing lines in the bottom. I spent throwing this plate trying to get it smooth. And now I'm just going to, with my fingers, make some whole throwing lines across the bottom to give the plate just a bit more personality. I like the way the glazes break on the lines. Anyway, there's throwing a large piece.
