Pottery making advice please

[JeffS73]

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?

 

[JeffS73]

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:

 

[JeffS73]

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!

 

[JeffS73]

Hmm, some sort of mind-reader you are?

Drying now:


I like the sprig moulding!

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!
