339. Making/Glazing a Sodium Silicate Texture Tea bowl/Chawan with Hsin-Chuen Lin 林新春 岩花瓷茶碗上釉示範

Today I will show you how I glaze this piece, if you see from the camera closer you see that this was the sodium silicate texture. You see that crackle texture. What I'm gonna do is that I'm going to glaze inside with the selenium. I usually pour inside of my teabowls or cups. I like to have a lighter color so you can see especially for tea that you will be able to see the tea color. So a lighter color so I will apply selenium inside and maybe up to here, right by the line here, selenium. And then on this portion, the texture, I will apply the black glaze and then wipe it. So the black glaze will go into the texture and when I wipe it I reveal that the clay body at a higher point will be white but with the texture black color so it will show nicely black and white and the bottom black and this part black too. Okay so that's my plan and to be able to wipe up the glaze easily while I'm putting on the wheel I like to show you this the plastic glass and the spinner so the combination I will be able to hold it in position and while the wheel is spinning this part is not moving because while I'm pushing it down the spinner is spinning freely so this part here I will be easy to wipe it up without pushing it away. If I don't then this pressure will move the parts away so that's the one other function for my plastic glass. Okay, two pieces together, I will show you later on. So first I'm going to glaze inside. Like I told you I will apply the selenium glaze so I always fill it up to be about maybe 90% on the inside. Of course your hand has to be very steady. About 90% and then you can just swirl it around so it's almost getting into 90% of the rim and then just pour it out carefully. To prevent the glaze from dripping when you pour out it can kind of lift. When you pour in and then it lifts so the glaze is not easy to drip out or even if you have a little bit of a drip, I have a little bit of a drip there so I can just wipe it up. Put this away and then I can use a sponge just wipe it up or you can wait till the glaze is dry. Just carefully scrape it off. That's the inside of the glaze and then I told you that I will glaze the black here and then after I wipe it up I will probably call a wax resist right by the line here. And then I'm going to dip it in the selenium glaze again later on. But for now I'm going to apply the black glaze. Before I do that I usually have this. I'm going to suck up the black glaze and then just glaze on the inside. So that's the black glaze. For pouring the glaze if you have a cup or something that you probably it's hard to find the right amount and with this it's very easy for you to just drip enough amount on the inside. You don't need to pour it out. That's just enough to go around the inside and you don't need to pour it out. So that's the black glaze. And then I'm going to put it on the wheel. By the way this is the absorber I showed you in my previous video. You can buy it easily from Walmart I think they have it or Amazon.com they also have it. It comes with a sheet and then you can use a scissor to cut to the right size. The way you just dip it in water and squeeze out the most water so this will create a little bit more friction while you put it on the wheel. It's harder for that to move around. And then I'm going to center my piece. And then I'm going to brush. You can use a brush or you can use this. Slowly drip it on. This time I'm going to use brush. Brush the glaze over. While you are using the brush make sure that your brush is very thick. Very thick here so it can dissolve a lot of the glaze. Brush multiple coats over. And then for the side of that I don't want to have too much glaze because I'm going to wipe it off anyway. So I will just maybe brush a little bit of water over. So when I'm brushing the black glaze, the glaze is not going to be too thick because I'm going to wipe it anyway. So I will brush a little bit of water over the crackle surface. I think I brushed enough and then I'm just going to lightly brush the black glaze over. So black glaze here and this is just lightly brush it over because I have some water that's over now. And I'm going to use the sponge to wipe it. To be able to wipe it, you need to have a down pressure. So this plastic glass is with a lot of a circle on top of it. So it will be very easy for you to find the center. Let's check. So this is very good. And then put my spinner over. There's a little groove there so it just fits right in there. So it's right in the center. And that's how I do it. Just hold it down. Let me double check. That's on top of it. I'm pushed down so my part doesn't go anywhere while I'm wiping. So it's very easy for me to wipe up the glaze. So you can see the black glaze is going in the texture part. So all the black glaze is going in there. Just wipe up the rim a little bit so I could have the center down on the rim. Okay. Put it back on the wheel and then I'm going to center it again. Like I told you that I will call wax resist here. So this is the wax resist. I usually like to put it on the wheel and do that. That way I will have a nice clean line there. So let's brush the wax resist. So this should be enough to just break it so while I'm dipping the center down glaze doesn't go all the way down here and cover up my texture. But when you are applying the wax resist make sure that you let it dry completely. So I will probably let it dry for like 15 minutes to 20 minutes before I dip it in the glaze. It's been drying for a while so the rim is dry and the wax is dry. And now I'm going to just dip on the rim already pour the center down glaze on a very shallow pan here. So I don't need to use a lot of glaze there. So when I put it in I will hold on it. So make sure that it's all the way around. And then slowly lift it up. Before the glaze dries you don't want to turn it. So let the glaze absorb by the rim before you turn it. Otherwise the drip might go back and drip it down. Just slowly turn it so let the drip come down a bit. Okay that looks fine. So now you see that because of the wax resist I will have a very nice clean line there for my center down glaze. Usually I leave this part without putting the sodium silicate so this part is smooth. And put in glaze over so when people drink the lip is not feeling very rough. So you have a glaze on the rim it's better. So that's the whole piece and I will file it and then I'll show you the result. So here I promised to show you the result of the fire after I glaze it. And now it came through the reduction fire. I fired to cone 11. Cone 11 reduction fire. The center down shows nicely. As you can see on the inside. The outside I brushed the black glaze. And also brush the glaze over the crackle surface and then wipe it. So here's the result. Thanks for watching.
