Just sharing what I've been working on, but open to others sharing their own learning experiences more than just tips especially if this isn't something you have tried yourself.
I've been wanting to throw some closed form lidded vessels ever since I saw another student in one of my classes make some really beautiful pieces. (It's an advanced beginner class so very mixed skill level!)
I threw this one with a large flange which I thought would be good for keeping a better seal, but it was honestly kinda shit (I trimmed SO MUCH) and it cracked so I'm not going to fire it. It only cracked after the underglaze too, of course...I had been drying it super slowly for weeks but that was just too wet apparently 🫠




I had a lot of trouble with that peice - and with most of my cylinders, honestly - where I end up eating up the base ro build the walls. I haven't figured out the limits of the clay yet in terms of what size I should be getting from what weight. It doesn't help that I use a grogless clay and am probably trying to get the walls way too thin to support the structure.
The massive thick walls you see above are a weird symptom of that. When I was pulling the top it barely met to crate a closed form and I kept manipulating it to try and flatten it out but that pushed the clay back down. Wack
Anyways, I tried to throw another one yesterday and make sure I kept it wider. The same weird thing was happening even before I got it closed. The walls just kept getting thick, but probably from over compression because I was so paranoid about the walls collapsing. I ended up giving up on closing it on the wheel and used hand building techniques to add a top and close it.
The walls were still too thin and it was collapsing but I fucked around with it on the banding wheel until I got something...okay. it's honestly very fun to manipulate the clay once you get a good seal. I added a knob.
I let it dry under plastic over night and then cut it open. Unlike the previous pot I didn't thin out a section to make a flange. I was inspired by the work of hand builder Marrisa Y Alexander, specially forms like this one.


Now I've got it in a damp box and I'll slowly start losening the lid over a few days until it's hard enough to trim without being too goopy.
I can throw pots with galleries and matching lids, but this is a very fun technique. I hope to figure out my issue with the walls and throw some bigger pots that are closed without having to add a slab and add that additional opportunity for cracking/splitting.
