For sure, the storage space is going to be an issue if I made anymore molds. Do you have any pictures of your molds you can share?All clays have a shrinkage rate when fired. If you want a 10-12% smaller pot make a mold of the pot that you pulled from the first mold and continue the process. Sooner or later you can get it down to mame size
The only bad thing with molds is the storage space one needs to store them and the fact that they only last for so many pulls.
That shit is tech. Nice work!View attachment 415495
After the 8 hour mark, the clay was firm enough for me to add my chop mark and drainage holds.

There is a support structure inside the pot that isn't shown. It's basically a sponge with a flat top and base.

Drainage holes and wire holes were applied. Note the gap in between the mold and the clay. This was a clear indication the pot has more or less separated from the mold.

Here is the pot removed from the mold with the support structure.

The ridge that was removed from the original pot was put back in.

This was the profile rib for the ridge/coil of clay that ran around the pot base.

Cleaning up, I noticed there were some areas where the clay walls were off. This showed how the top warpage affected the opening.

More finishing was done to the exterior walls. That coil added back into the pot was like going full circle.

Top view. The pot is now ready for feet.
My focus is on smaller pots, mame size. Here's one I just recently did and tossed out as the plaster was old. I just got a new bag of plaster so when I get some time this weekend I will start back up with the molds.For sure, the storage space is going to be an issue if I made anymore molds.

I wish I didn't waste my time using that old plaster. I now have to basically start all over to make that mold. Doing a one piece mold is a lot faster that was what @ABCarve mentioned earlier in the thread.Wow you really got it all figured out. That form is clean as anything!
I have a lot of projects going on......just need more time to finish them.Looks like you got some root stand blocks going!
Murphy's Soap is technically a cleaning vegetable oil.No picture update but the pots have been fired to bisque and no faults have been detected.
@Pitoon I use murphy's soap as a release agent. in your experience do you use any other that may possibly work better than the soap? I say this because the soap tends to gel up for some reason and it imprints those gel'ed up bits. The larger bits I'm able to remove, but the smaller ones also leave small imprints.
Good to know. Thank you!!Murphy's Soap is technically a cleaning vegetable oil.
I use an actual mold soap from Laguna....... https://www.theceramicshop.com/product/2546/pure-lube-mold-soap-1-gallon/
