Great work but dam you! I keep feeling the pull to start making pots. I don't need another hobby but It's posts like this that make it hard to resist.
Building a wet slab bonsai pot

It is stoneware clay. It is a sculpture mix. It has a lot of grog in it. This makes it more crack resistant when drying and firing . You can’t use this type of clay to throw with as the grit would tear up your hands.

I’ll try to do this when I start making pots again this fall.

Jean Luc,
just look for a small second hand kiln.
Clay is free.
Tools are carved wood.
My brother-in-law hand builds, just clay and
a dowel as a rolling pin. Any shape.
Very relaxing to do or watch.
Good Day

I have another question... how do you place the slabs over the mold? do you place it and then cut it?
How long do you leave the slabs dry out to be leather hard?

I use the slabs as soon as I put them through the slab roller (wet clay). They are cut to a generous rough size and then formed to the mold. The excess is then cut off. How long to leave it for leather hardness depends on your own environment. Every studio is different.

So I started making a mold with high density polystyrene... wish me luck.

The foam I use carves a little better than the polystyrene but I think it will work just fine for what you're doing.
If you use a simple shape like your oval you don't have to cut it into quadrants especially with the angle you cut on the sides. That a good place to start!! Good luck!!

I gave it a try. My shaped plastic was too soft and didn't really work well.

Why do you say it is too soft? It seems like your issue is inconsistent wall thickness. I use a slab roller which does a nice job. Try rolling your slabs with two thin pieces of wood (desired slab thickness) as a spacer for the rolling pin. Try something smaller first. Doesn’t look too bad for a first try. Practice, practice, practice!!!!!

@ABCarve On the bottom, the supports you use: are those removed after firing? I’ve started putting a central support on larger pots because of potential slumping issues. I know it isn’t the most aesthetic solution whenever look at the bottom. I’ve been looking for a way to attach supports for firing that I could remove. Since I don’t have the luxury of loading my own kiln, I am at mercy of the Studio tech and the kiln gods.

My wife is a potter and I have access to her studio, clay stash, tools, and kiln. This technique will come in handy this winter, thanks!

Those supports have newspaper under them so they don’t stick. However they are used in the firing so there is no slumping issue. They are not permanent.

I'm with @Bananaman on this one. Your pot looks amazing and the quality of the work is top-notch, but I would be concerned about the concavity. I have had to cut trees out of pots before and ended up retiring the pots (even if I didn't break them).
Function needs to be considered before form

Better yet... your next pot can expand just like your form, so when it comes time to repot you can just expand the pot and the tree comes right up!
