I decided to take a punt and go for cone 6, about the limit before the shrinkage went negative on the graph:

Looks like your angles moved just a touch... This is normal.. and can be anticipated for.
What does your "ramp" look like for the first 3 hours?

Thanks, yeah, details count!! I've learnt a lot about how much there is to learn to make a great pot. Pleased with the start though.
I read that burnish burns off well before cone 6, but I'm glad I gave it a go:

Yeah, struggled to keep everything square and true!
Ramp was slow, it was 175C per hour to 1100C, the 65C per hour to 1200C with a 15min hold, then free fall.
Cones 5,6,7:

I think the photos are a bit off, I've taken them close up on my phone, theyre not thay skewed! Both pots stand flat. The rims curled a bit, and the transitions between the sidewall and rims are a bit rough.

Oh yeah.. they'll sit true! Even if you melt them into a puddle... it'll still be flat.. where it's touching. I was just noticing that the walls seemed to bow (This just happens.. frequently) in between the bisque and full-fire pictures.
My best, personal way of combatting this.. is being aware of gravity and forces, internal and external, during the drying process.. that and making sure my first 3 hours are within 900-1100F but it seems like you are firing slow.
That's close to 350F an hour So by Three hours you SHOULD still be within quartz inversion temps.

I really like your moulding-looking foot detail.. and believe you should flex those muscles and see if you can use it other places throughout your pieces.
I'm excited to see what you do NEXT!

Hmm, some sort of mind-reader you are?

Oh man! That's exciting! I like the direction a LOT!
Pretty soon, your curvature-finishing skills are gonna 'hop up' to fill that method-space..You're gonna make those little moulding SHINE! Make em.. SHINE!!!!
I have a feeling that your designs, soon, will be exactly as you want them to be. Please update this one after you finish your dry work!
