should have FULLY allowed clay articles to AIR DRY! slow moisture purge and evaporation. THEN fired. the remaining moisture in the clay caused your crackings!
It may have cooled too quickly, clay and glass firing equipment usually has fire-brick surrounding the firing area to insulate it, and let it cool way more slowly than the bbq cools... a bbq will be cool to the touch in a matter of an hour after the fire dies, where the fire-brick ovens that fire glass and ceramics will stay warm for much longer than that...
I've had similar problems melting glass in campfires... you put the bottle in, and inevitably its broken somewhere by morning, even if you just let the fire go out slowly...
Could be the case but a coal of fire of that size dying out naturally is a pretty slow process. It should work. But extra insulation would be helpful anyway. I personally think the heating and cooling down between stages is where the cracks happened.
This is also something that might be solved by using some sort of refractory insulation like they use in their propane crucible, as you would get a more even heat, and wouldn't need to keep opening it and moving the bits around...
Just a quick tip. Like you said, the only ones that broke were the coil pots. Thats probably because they weren't held together well. If you're doing coil, you have to use something called slip which is usually just clay mixed in water. It should be like a paste. You would use that as a glue to keep pieces together. More importantly, you made them as one coil. When doing coil, it should be done one coil at a time not just a long coil. That long coil prevents you from being able to score and slip then together. Scoring means putting marks in the clay so that the slip binds them together better. If you try that, it should prevent extreme cracks like yours was. Much love, someone who just finished his first semester in which he took a ceramics class. Hope that helped.
You're supposed to knead clay while wedging it. Throw it down then push forward and roll it up then repeat. Also slip and score the coils or they won't hold together and don't forget to pinch the coils together to bind them together.
Clay Shimon I need to ask a question y do we need art and world history and algebra in school what are we learning on world history and when are u Bing to use letters in math in the real world
Yo I’m a bit late but the natives never scored it and their pottery style still works. You can simply pinch and schmear it together. He should’ve definitely schmeared it down some.
Wheel Potter - Thoughts on clay cracks - All clay has a percentage of shrinkage when it dries and when it fires. this can be anywhere between 4% to 15% shrinkage. Depending on the size of a piece this can be very minimal (1/4") to over an inch worth of a difference. A piece that has thinner spots vs thicker spots will dry at different rates and change how the piece shrinks uniformly. If a part of the pot shrinks faster than another part, it will separate causing a crack. The Clay needs to dry slowly until it is ready to fire to help prevent cracking. Porcelain is a very fine clay with no grog, it is quite strong when fired, but it also shrinks the most because as it dries the clay particles pack together tighter. The more grog that is included the less shrinkage you will have. Primitive technology was able to quickly dry his pieces by a fire due to the large amount of grog and impurities in his clay that prevented the clay from shrinking so much. A method that I use to help dry slower is to place a bucket, or other solid container, upside down over the piece, on top of stilts to allow a small slit of airflow from the bottom. I've used popsicle sticks, or even 1" thick blocks to raise the upside down bucket a bit. This creates a sort of "damp box" that prevents the moisture from escaping too quickly. Depending on the gap in your bucket, you can extend the drying time up to a few weeks.
Two things I notice. One was your wedging technique. You're supposed to toss it through a stretched wire or fishing line onto a table then knead to further work out any bubbles. The other was using plain water to get the coils to stick together. I was taught that you had to use a thin paste of clay and water known as "slip" to act as a glue for hand built pots. I hope this helps in future projects.
Sort of, but the things he made were more made for heating metals than they were for firing clay. Clay requires temperature control over long periods. Metals don't. More traditional pottery kilns are a different beast.
When I as in my ceramics class, my teacher always had us loosely place a plastic bag over our works to either keep them moist and workable for the next day, or to let them dry slowly. If you just leave them out in the open right after working them (probably like what you did), then they dry out and shrink too quickly and that's why they crack. When people say to let ceramics dry slowly, they mean REAL slow, like 2-4 days of slowly letting it dry out.
Yes. And joining the top roll to the one beneath by pushing it down into it. But it wouldn't have worked anyway, because the clay was probably to lean.
If you put food coloring in water and then put it in the distiller you used in a previous video and would the food coloring evaporate with it and land in the top or would it stay behind
If you would like to see that video you should go to another UA-cam channel named "How to Make Everything". He has already done this and made a very interesting video
I have not tried this method but I have been successful in using a chimney starter and sitting the clay on top I used hardwood lump charcoal and it made the clay glow orange I kept adding more and moving the clay up i did this for about 4 hours and ended up with sintered clay
i found when i fired clay when i was yonger what i did was get a propane stove that is designed to put a pot on , and a rack for the clay. then i put the clay right ontop f the rack just above the flames, then i put a metal coffee container on top and waited about 20 mins they turned out great
I'm a ceramicist, and the trick to keeping your clay from cracking is holding it a 200° F for two hours before increasing the temperature. This removes all ambient water. After that, increasing temperature by 300°F per hour is what I do.
Just a little tip for the coil pot: You should just connect each individual coil to each other by stroking your thumb up and down instead of side to side :D
that was fast, you went and bought clay, or found it, worked it, and formed a play button. Then fired it and set it all under 20 minutes? thats insane, you should start a business
Kilns run at 1000 degrees.. a BBQ typically about 450 with some 4 burner versions (like ours) reaching 7-900 with all of them cranked all the way up. Still not hot enough... NOW the forge on the other hand can reach 1000 easily so if you made a large propane forge you could use it for firing ceramic... BUT you'd have to have a huge propane cylinder as they typically are fired for 24 hours.
On the sides where it broke off, it may have been that you didn't smooth the insides. And besides it would eliminate any cracks where water may leak... i made a coil pot in an art class once and the teacher made sure we either smoothed the inside or outside because of that reason. She said she's had experience with the coils breaking off if it wasnt smoothed out. (Plus it helps with cleaning if its on the inside. Because less cracks and crevices for food or whatever to get in)
That Focused beam of light and Heat would turn the water inside the exposed section of clay into steam, its basicaly the same result as you'd get when you put a undamaged Potato into a Microwave at 1000 Watts for 5 Minutes, it explodes (Though on a much smaller scale).
You can add paper pulp (cellulose fiber) or cotton fiber into your clay in a 1:4 or 1:5 ratio, well mixed into a slurry, to add strength and prevent shrinkage and cracking in the drying phase. Also I'm honestly not certain your pots were actually fired. To fire clay they should get red hot past quartz inversion into vitrification and stay there for a few hours, and then cool down very slowly. The goal is to form strong crystalline structures from the heat. Most BBQs only go up to a few hundred degrees in temperature, which only really removes humidity and burns off impurities. Before firing if you tap your fingernail on a dry pot it sounds like wood, but after firing it should sound like porcelain or glass. The way they broke apart proves they didn't get to vitrification...
I have an idea. Try making any kind of mold for gelatin, and use thermite with the gelatine and see if it will light. If it doesn't work the first time, try using a smaller amount of gelatin and water.
Cut scratches in the tops of the coils with a nail as you make your pot and slightly moisten the scratched clay. That will make the clay stick to itself better and lessen the chance of bubbles and cracking when you fire your pieces.
I've done pottery on and off for many years, but I've never heard of mixing charcoal ash into your clay body to help prevent cracking. Years ago I did mix various natural fibers into my clay body to make it stronger while it was in the greenware stage because I was making some extreme textures in my sculptures - it worked beautifully, but caused a very smokey bisque firing. Anyway, I'm very curious where you heard about using ash in your clay body - I'd like to check it out. As for your technique of forming your pots, I would strongly suggest you sign up for some type of ceramics class at your local community college. You've got the energy and enthusiasm to go a long way with some quality instruction.
im in a ceramics class currently and thats the first thing you learn and also the wedging the clay isnt just throwing it on the table. so that didnt help either because it wasnt wedged correctly.
I was taught to never use a true coil base. You take some clay and after wedging have it rolled to the thickness desired. You don't want a thin base, nor do you want a thick one. The cracks he allowed would've definitely caused trouble as well. We were taught to monitor our pots as they dried, and if cracks began to form we could reinforce it with more clay and slurry.
Having worked a lot with Ceramics myself, it cracked because he made the walls so uneven. If the clay is the right consistency scoring isn't necessary and with that small amount of clay it looked like he wedged it right, as long as he did it for an extended period. Having watched the video making the clay, I think they left too much silt in it as well, as well as dumped too much clay, so it cracked from that too.
the clay cracked because you didnt scratch and slip (scratch clay that will me connected to other clay and you didnt slip, which is were you put verry liquidey clay- kinda like a smoothy) this keeps the clay from cracking because it bonds together the pieces. also as you could see when you were coiling the clay pot, the clay started to crack. this means the clay was too dry, so just add a bit of water and that will go away. great vid by the way! it might seem like i am just tearing you up, but thats not what im trying to do. just simply giving advice.
Hmm a Thermo-Can filled to the brim with Dry Ice and some water (For addtional Prssure) to then putting it into a Fire. I belive the fire will be extigushed by the lack of Oxygen, and possibly the Shockwave of the Exploding Thermo-Can.
I want to see a portable power bank or power station that you could use as a backup battery at home for when the power is out or if you want portable power. station.
you should attach the shop vac to the bottom of the grill and put a mesh wire over the vacuum hole so charcoal wont fall in and it will super grill stuff
It's been a while since I've done any pottery like this but I do believe you need to let the clay sit for several days after shaped. I don't know how long you waited but it did look like it was still a bit wet. Water will do the same thing as air bubbles. Plus the manufactured charcoal does not get as hot as real charcoal made from wood. That might have helped getting it hotter. Then there is the cool down process. Putting it is in a raised grill will cause it to cool down way to fast and that will cause thermal stress. The best way to fix that would ha been in an insulated oven partially in the ground. Or something similar to the metal foundries you've used in your videos, only bigger.
You need to let the clay dry for some days so it becomes bone dry. If not, it can easily crack in the “kiln” due to the temperature difference. Make sure to use slip, aka soupy clay to connect the coil strands. Also use a lot more clay on the base, those coils were a little too skinny. Get a tool and smooth it out, also apply some glaze so that it becomes a semi-permanent waterproof bowl. Trust me, I’m in ceramics and I LOVE it
I use an old hair dryer as a source of air.. the stream of air is much stronger and more concentrated :) Use a funnel and a metal pipe to concentrate it into the center of the fire.
I recently took a ceramics class and I think I know where you went wrong. You said to dry the clay in a dry room temperature room, but that is exactly the opposite of what you should do. We let clay dry out in a warm, dark, extremely humid room known as the damp room. This allows the clay to dry slower and evenly on the outside and in the center of the clay, which helps prevent cracking. We also used clay with grog in it by the way. It could also be the clay you're using or the barbeque, but that seems unlikely to me.
One of the major reasons pots cracked is due to abrupt temperature changes during firing. Cold tongs, exposure to cool air and extreme heat. The pots experienced heat shock each time you open and closed the lid. You need to have a way of gradually heating the pots and adding fuel without dropping temperature
I found it painful too. When they made the clay they pored out too much clay and left too much silt, then they built the pots with all the skill of a 3 year old😢
“Clay... I’m sorry but I’m gonna have to let ya go”

Can you use the solar scorcher on clay to see if it will turn to pottery?

You can add paper pulp (cellulose fiber) or cotton fiber into your clay in a 1:4 or 1:5 ratio, well mixed into a slurry, to add strength and prevent shrinkage and cracking in the drying phase. Also I'm honestly not certain your pots were actually fired. To fire clay they should get red hot past quartz inversion into vitrification and stay there for a few hours, and then cool down very slowly. The goal is to form strong crystalline structures from the heat. Most BBQs only go up to a few hundred degrees in temperature, which only really removes humidity and burns off impurities. Before firing if you tap your fingernail on a dry pot it sounds like wood, but after firing it should sound like porcelain or glass. The way they broke apart proves they didn't get to vitrification...
I have an idea.
Try making any kind of mold for gelatin, and use thermite with the gelatine and see if it will light.
If it doesn't work the first time, try using a smaller amount of gelatin and water.

Mr. Wonderful he murdered and replaced him

You need to let the clay dry for some days so it becomes bone dry. If not, it can easily crack in the “kiln” due to the temperature difference. Make sure to use slip, aka soupy clay to connect the coil strands. Also use a lot more clay on the base, those coils were a little too skinny. Get a tool and smooth it out, also apply some glaze so that it becomes a semi-permanent waterproof bowl. Trust me, I’m in ceramics and I LOVE it
King of random you should see what will happen if you put clay in the vacuum chamber? And you guys are cool.
You should make your own pottery glaze and use it with your DIY clay!
rainyjacktheepic he should do metal oxides
You mean, once he figures out how to fire his clay without destroying it?
put the clay in a vaccum chamber before toasting it!
Edit : I said toasting but i wanted to Say burning it
Paul yeah!
oui oui

Ah, Toasted Clay. Its like Fresh clay but warm and a bit dry. Now that i think about it, toasting clay is a faster way of drying it (Possibly)
it is too thick for it to work
Make a soap bubble gun that shoots lots of bubbles! Without having to dip it in soap
Who misses the original king of random
I use an old hair dryer as a source of air.. the stream of air is much stronger and more concentrated :) Use a funnel and a metal pipe to concentrate it into the center of the fire.
Clay: I can’t work for you anymore
Why?
Clay: It’s because I’m fired
I use a clay pot for an oil lamp
Not if it's glazed...
😩
Why are you everywhere?
Just everywhere
a-lpha of Zeldaforme Gaming Smart
Jingle bells jingle bells jingle all the way oh whats fun to ride a horse completely made of clay
Conner Schmidt Nice you got a like
I recently took a ceramics class and I think I know where you went wrong. You said to dry the clay in a dry room temperature room, but that is exactly the opposite of what you should do. We let clay dry out in a warm, dark, extremely humid room known as the damp room. This allows the clay to dry slower and evenly on the outside and in the center of the clay, which helps prevent cracking. We also used clay with grog in it by the way. It could also be the clay you're using or the barbeque, but that seems unlikely to me.
One of the major reasons pots cracked is due to abrupt temperature changes during firing. Cold tongs, exposure to cool air and extreme heat. The pots experienced heat shock each time you open and closed the lid. You need to have a way of gradually heating the pots and adding fuel without dropping temperature
What happened to the main guy?
He is sick
carolyn mmitchell really? I thought it was family time off... ?
I love your vids
we want the old king
XP gaming yes
YUPS
Nah
email him then
ikrr where is he???
Should try scoring (lightly hatching to create groves)and using slip (watery clay paste) between coils to make a stronger bond.
You should put the clay in the vacuum chamber and try to see if that gets all the air bubbles out. Then fire it and compare it to the regular clay.
You should have used the vacuum chamber to pull out any air bubbles in the clay
That wont work i belive, Clay isn't Marchmellows ... or Slime ... or Oobleck by that matter.
Wouldnt work
But we like watching him fail!
It can be done, but not with a standard vacuum pump. He needs to add a pug mill to the vacuum.
The water in the clay would boil, possibly causing more cavities and drying the clay.
Can the Solar scorcher fire clay???
Evil Morty probs not, too hot
Do you know how hot kilns get? The problem is that the scorcher focuses the heat. You need an even distribution.
But it would be neat to see :D
Rick and Morty is for below average intelligence people. Have a nice day.
Dan R. Hansen not really i watched rick and morty now my IQ is 300
As a ceramics major this is very cringey
Giles Hayden as a ceramics major, perhaps you could offer advice to improve rather that just stating the obvious ;-).
I found it painful too. When they made the clay they pored out too much clay and left too much silt, then they built the pots with all the skill of a 3 year old😢
An elitist who offers no other advice. Cool thanks.
Primitive technology makes this look so easy
I just watched that old Clay video yesterday and asked if you could make and fire casting molds! Lol
Love your vids. Can you put U.S coins in the metal furnace please👍👍👍
Ha nice idea
Mashrafi Rahman haha yes it is a nice idea
Smh he didn’t score and slip he only slipped did this dude even take art class
Scυb Ŧσσ ᑕσσl not even slip used water
Living in a place that is pretty much always summer is probably great for doing experiments
The duke of random has arrived and is here to stay
