883. Throwing a Sectional Closed Form on the Aluminum Bat System with Hsin-Chuen Lin 林新春 接坯示範

I'm going to use my bed system to throw a section pot. One section, two sections. Stack them up and then continue to throw. This is about three pounds of clay. Put my bedding in here and then line up my logo here all together. So next time when I remove and put it back, the logo is a reference to put it on the exact same spot. I'm making my base a bit wider so it's easier for me to take care of the pattern flow. And then after that I cut it in and raise it up. Since I'm continuing to expand the volume, I leave this part here slightly thicker so that after I stretch it, it will be strong enough to support away from the path. I use a torch to dry the base piece a little bit so when you have another piece stuck on it, it's not going to collapse the bottom piece. I'm going to join them 45 degrees, slightly angled, about 45 degrees. And now I can remove my base from my bed system. I'll put it aside. This will be the top piece. Both are the same weight, about three pounds, but the top portion could be a slightly smaller. Since I'm going to attach it upside down, I don't need to have a open up the base completely so there's no clay on the bottom. Then you're going to flip it upside down so you don't want to have the base too narrow. That way it might fall down. So you still need to have a bit of clay to attach on the bed. Make sure they are the same diameter. I will go for the outer part. This will be the outer part. It needs to come in a bit. The outer part, outer part, inner part, inner part. I could come in a bit. And then I would use a torch to firm up this part here a bit. But you don't need to firm up the bottom. Because later on you might want to do something to finish the top. And brush slip in between the joints. Remove and put this piece aside. I'll go to local. Your bed system is in the very center. It doesn't matter which direction. But sometimes people, when they do, they kind of slightly shift the whole piece. It's not in the very good center. That's why you need to put it on the very accurate, the same spot. Put it upside down. Carefully flip it over. Looks good. And then you can use a wire to wire it off. Or you can use a knife to cut it. Let's use a knife. You don't need to cut it all the way here. But if you want to use the most of the clay, you can cut all the way to the back. You don't have to. If you have enough clay, you can just cut it right there. All right. Not a very good cut, but you can always make the rim level later. But now the important part is trying to make sure the joint is a good joint. Then you can use a hand to slightly squeeze the joint. Now we use a heat gun to dry a little bit so this part here is strong enough. Okay. And then you can use a double rip to compress it. I'm going to use my number two and number one wooden rip to go inside and one holding on the inside and one on the outside to compress it. All right. And then I can come back here and slightly stretch it from inside and stretch it so the shape follows through from the bottom to the top. So you can see that when I'm stretching it, I seldom use water. Just grab the rip on my hand and my inside has a smoother area touching the surface so it's not actually creating a lot of friction. All right. I brush some water here. I try to pull more clay from here and make the opening small. So usually I use a sponge to just lubricate a bit. All right. And then I use my number 17 skirt trimmer to finish up the foot. And I probably want to trim the foot just a little bit like that. So I'm just wet trimming actually. Section part. Two pieces together and the stretch is fairly thin already so you don't need to. You don't want to trim. Just leave it like that. All right. So this is the section part. If you're going to disguise, sometimes after it's dried or during the fire, this part you might come out. If you're going to disguise it, you can do a little bit of a surface decoration so people won't be able to notice that this is made from two pieces of clay. Let me do a bit of a disguise line there. Okay. So that is the finished piece. And then you can use a barbacoa wire to cut it so you don't need to trim at all. But I need to pop a hole because this is closed foam. So I will just pop a hole right here. Right there. Just a tiny hole. All right. So this is the section part on my bed system. So you can throw one and remove it, put it aside and then put another bed insert and throw. And then put it aside and then bring back the original one and then stack them up and then keep on throwing. You can make whatever the size you want. You can make smaller scale or larger scale. If you want it to, you can keep on stacking it. So it will be big. The limit is your kiln. So your kiln size is your limit. Otherwise you can make it wider or you can make it taller too. Okay. So that is the section part. I've done this technique a long time ago. Now a lot of people are doing it. So I'm just going to, I just show you that this is my bed system and it's very good for doing so because when you heat it up, it's on my aluminum bed. So the insert, so it's not going to ruin your bed. And also it's a little bit lighter weight too. Right. Thanks for watching. I will see you in my next demonstration.
