Wow, thank you so much!

yes

Glad it helped!

Good point but the same technique could be used on a more elaborate piece, right???

@@bobm2331 Right. If this was just an example. then it makes sense. I agree.

As a teacher, I experience students who are always pushing the boundaries of what can be done and crying because their piece gets ruined. Of course, you are exactly right, but as beginners, I could have them throw the pot on the ground and learn the lesson of loss, or I could show them how to fix a problem. Realistically, you should only use this on something that took you days to complete, like something intricately carved, or a sculpture....this is only an example that was fast and easy.

It can work, but porcelain is super difficult. The problem is it has a really good memory. If you accidentally knock it even a little, it will crack there. I would just re throw it, but you could try.

Sorry for the late reply. It's the only way to get the shape just right. If you form it by coil, it usually ends up deforming and it is difficult to dry that way. This way the entire piece firms up on the outside and then you empty out all the damp clay. It uniformly dries and retains its shape very well.

I was wondering the same, why vinegar?

so, i found this in another video of theirs "Water on its own can cause your clay, when drying, to actually crack apart. Imagine the dry desert, the reason there are so many cracks is because dry clay swells when it gets wet and clay that is too wet looses its ability to stay together. If you use a medium like vinegar, it causes the clay particles to slip together, not swell."

have any of you tried this?? and is the crack visible after firing or is it gone?

it is usually smoothed out and no longer visible other than sometimes a bump depending on how good you smooth it out.

Yes, that is exactly right, I apologize for not keeping up on comments.

Exactly, thanks for filling in the information!

Awesome!!!! Glad to hear it! I try to teach my students at University, but it's too much for them with grades and all, glad it helped!!!!

I know, it's a very difficult process, just keep trying. Make sure your coils are clean and not too lumpy. when you make the coil be sure to roll without pressure, just the rolling motion will extend it and you will get less of a lumpy texture. Lumpy coils lead to bubbles. I'll try to put up a special video on the recenter pass, that will get your clay re-centered.

The more clay on the wheel the harder it gets. There's a definite physical limit based on your form, skill, and strength. If you look at a lot people who make large pieces they try to throw as much as they can as a base then either add coils to make it larger or throw a second, third, etc. vessel to attach to the one below.

@@robw1571 Watch skinny Asian potter videos. A lot of them throw 25kg or more; huge moon jars in one throw. Others throw two section moon jars and join. I guess if ya gotta coil that's fine; I'm not knocking it; just don't understand why other than strength issues but I've seen skinny little Korean girls throwing 25kg or more without coiling. I can't do 25kg (yet) either. :-)

I have tried the 25 lb technique, but never got above 2 ft. I also like my pots thin and with that technique I was always left with thick walls. It's all about practice. And I am definitely not a girl who wants to show off my muscle. I work as a mechanic part time for my husband, so I know my limitations...lol. With this technique, it is not as hard on my body and I can get a pot to around 5' tall, and I know I could do more. But, with the 25lb technique, I just haven't practiced it. :). I love cats, so no offense, but "there is more than one way to skin a cat".

For large pots,, the Onggi method is the most efficient method to get stronger and thinner walled pots with very low physical effort. It can also be done with flat slabs instead of coils. That is even faster. However, the above video does not show the full Onggi method which also involves using a wooden paddle and anvil to compress the clay and make the walls thin.

Yes, if you want to get more out of the attached coil, you need a thicker coil. Thin ones work, but then you have to make so many more coils.

Glad you liked it!

yep, that would totally work

Thanks!
