810. Throwing a Sodium Silicate Texture Covered Jar with Hsin-Chuen Lin 林新春 岩花瓷蓋罐拉坯示範

centering you don't need to speed speed up the wheel the key is freezing your hand my right hand is breezing on the scetch pan and the push down the clay okay and you can see that my hand not I said I'm using my center of the Palm to push the clay I try to use more of the fingertip here and this part here and just pinch while using my left hand see that this is the part that I push and this hand is just pinch squeeze and pinch and then while I'm squeezing down using my left hand and just place all the fingers together holding the hand and push down as long as your right hand is not moving it's fairly easy to Center the clay this way when opening them taking it down use my left hand and again my right hand is bracing on the splat flash pan left hand is kind of a brazing on my right hand and squeeze it all the way down to the right thickness before I open it wider and again the speed of the wheel is not super fast either and now it's good thickness and then I'm starting to widen the base and again using my right hand to to brace it and left hand is touching the right hand okay so that is opening and the floor is not quite flat or straight you can use a your fingertip or I have a tool here that is very nice to use just Brae it here hold it together and if your wheel is spinning counterclockwise just compress it from the right hand side push it it all the way and then move the tool to the right and the FL is very flat and also you will have a very sharp corner by when using this tool this corner is very sharp hold it down and and then braise it and then push down and pull to your right so this is what this tool is all about this part here is for FL compressing I'm now ready to raise up the wall before I do that I could color it a bit squeeze it both hands squeeze it especially the uh the very corner here when I'm color this right fingertip is pinching the clay squeezing in so you don't end up with having too much clay hanging out there all right and then I'm ready to raise it up since this piece of clay is not very big or very thick so my initial lifting is just using my left hand I grab the clay and pull it and lift it up right and and then this right hand is again connecting on the splash pen and then hold it here so the thumb is touching here right there so at the left hand will be more stable and this hand is holding on the side of it and pinch the clay and just raise it up all the way to the top and again put all the slip back to work and C collar to make the wall straight and this part here pinch it in this two fingers pinch it in make sure it is slippery everywhere and again start to lift the clay from this corner but you see that my thumb is too short but I still want to do the same thing like a lifting the wall so what I do is extending my right thumb here right so this is the hand this part here slightly touch it and extending my right thumb Pretend This is the left thumb and then rest my my elbow on my LA to uh to stabilize it right there and pinch the wall and slowly let go and compress remove the slip up the fingertips and put it on the inside of the wall for outside just touch it up with a little bit water and little bit slip and you brush up and down to Mega slippery and again there's a steel clay hanging here you can pinch it it in you can use this finger to pinch it it in okay I'm going to do the same lifting M the thumb is too short so extended my right thumb my left thumb is too short so extended my right thumb and this hand slide it hold it not much pressure here right together going pinch and slowly to go slightly compress the rim brush that slip brush that water and slip okay I will do one final lifting clean up the corner okay since I'm going to do the solum silic stretching so I tend to leave my wall slightly thicker little bit thicker than one qu of a inch quarter quarter of an inch and now I'm going to get the surface clean using my number three wooden rib so many I just use my fingertip okay my fingernail and the fingertip to draw the texture all the way to here with the fingers inside to support it right and clean up my B before I brush the sodium silicate I like to clean clean up my B even the corner here I like to live about maybe depending on what you making the pH the coverage I like to leave about 1 in without brushing the sodium silic on so this is about 1 inch here and a brush down below the thicker the sodium cic and also the thicker of the clay wall you will get a bigger crack crackle texture and of course thicker you could stretch it farther away so you will get a bigger crackle and I usually just wash my brush in the bucket of water little bit of sodium silicate is not going to affect too much so just wash it in the bucket of the water and now I'm going to bring my torch or heat gun you can to use torch heat gun hair dryer uh if you're using heat gun is very powerful so you probably all you need to do is maybe like 30 seconds for the dry service and the H Gun I would say maybe 1 minute on hair dryer maybe 2 minute to 3 minutes okay dep depending on how hot it can go and my gun can go up to like 4 500° fah so about 1 minute should be plenty all right I can see that there's still a little bit shiny on the deeper Groove but on the higher point the Shan goes away so that's that's the that the stage that I'm looking for and now you cannot touch the outside any longer anym so just leave it alone and put your hand here right hold it on the side side of a splash pen but inside you want to be a slippery so use the sponge and add little bit water to the sponge and then you want to coat and rehydrate or brush the slip on the on the inside the wall right so now the inside is slippy enough and uh if you want to get a a nicer better curve you can use a rib I'm using my 3 in small the smallest round rib to go inside and stretch it in e right so that is 3 in round RIP just grab it put my finger there grab it and using from this part here all the way stretch to this part and do the fine tune using just my fingertip and my fingertip is like here slightly touch and little bit more touching here right so usually I will get my bottom portion nice nicely curved before I take care of the top and now I think the bottom portion looks good so I will stop right here and start to take care of the top for and my personal preference for part or even the te part is keep this part here simple just a little lips there and then I put the gallery on the lid and that have be slightly up not level so I'm going to use my knife to cut it use the knife to cut it level right so that's it for the body and then just chop the uh I want to clear up the bottom okay so the tool you see I'm chopping up the corner using my skirt trimming wet trimmer this is my number 17 if you are spinning the uh the wheel counter CL wise or if you are spinning the W clockwise you can use my number 18 trimmer wet trimmer okay so that is the shape and before I put it aside I need to measure the width okay so this is about right now making the lid for the sodium silicate cover jar I'm throwing the lid upside down meaning I will trim the knob later and then I open the shallow shallow dish in the meantime you are going to keep the outside part slightly thicker because you are going to push the gallery here and basically you are just using the thumb to form the inner part and I find out the thumb is very good for throwing the lid is that the thumb this part here you have a very nice curve this curve and you can use the curve to push the inner part of of the clay of the dish let me just follow the curve nicely before I go further I want to know what approximately width of that so it's it's getting closer just a little bit and then I will push the gallery here so give myself a roughly idea where is my gallery be put my both finger here and this right index index finger is just squeezing from the middle so you will see that it's roughly the the gallery will be here bring back my caliper and see that it's fa close and just do the fine tune for making the gallery you going to use this tool is is a good tool to use but make sure this is nice 90 here cuz when you're pushing you are going to form the 90° so if your wooden rib is doesn't have a good 90° get a sandpaper and then just sand it so this part here you have a nice 90° and this is my number one wooden rib now you see that when you push down you got a nice 90° there and the the inside hand slightly push against this part of a wood rip and double check okay slide it is smaller so I will push more from the in inside push out from push out from inside to stretch it a bit okay that that's good so I will just finish it up better right so the G is forming nicely let me double check again final check okay that's good and around the corner here so I like this part here slightly slanted okay so it's easier for a little to a drop pin so I push the top portion slightly in so the bottom portion is a little bit wider than the top portion and the size of this part here hanging out but if it is getting too wide you can use a a good knife to chop it off or you can do it while you're triming get trimmin it off so either way it's fine let's do it now let me show you this is my number 10 tool hold it steady and then just chop keep it straight and you cut so it's very easy to cut because this place is the tip is very thin and the bra is thin so it doesn't have a lot of resistance so it's very easy to cut it so after cut it you can see that this part here is slightly white too white you could trim it later but the I personally prefer just do the wet Tri in so Tri it wet the key is holding the tool fairly steady and then take your time and take it all the way down to until you touch the B so I remove a bit more clay from the side of the wall little bit clean up okay so that's how I make the lid to fit the body and I slightly prefer this part here is wider than actual size so when I'm trimming I could slightly remove either clay from here or the clay from the body so they will fit tight okay so this is what it look like and uh still have a quite a bit of a clay to trim but uh I already removed lots of them and I will show you how I finish triming in the later video right so that's it for my demonstration and uh see you in the next video
