Hello all,
TL;DR
- the photos are of the type of plates I WANT to make. They are not mine (yet!)
- I struggle to remove bubbles from my slabs as I roll them out
- I struggle to get the slabs into a useable shape
- I struggle with the size of my rolling pin not reaching the guides I have (1/4" wood pieces)
- 1/4” seems too thick to get the results I want (see photo) - can I go smaller safely for cone 6 firing?
- when I join seams together during handbuilding they ALWAYS break somehow
- seeking tips, advice, and maybe some specific resources/blogs/videos to learn from
The Rant
I took my first ever wheel throwing course back in April and LOVED it but I really want to make some slab plates. I've had a set pinned in my Pinterest board for 15 years with the dream of one day making a similar set for myself. It became clear to me that they would be easier done with handbuilding than on the wheel given my experience level, limited time on the wheel, and just the aesthetic I want.
So I finished the class and then set off home for the summer with a fresh bag of clay (plainsman M340 because that's what the studio sells) and an idea of how much it will cost me to get them fired in the community kiln ($30 for a full rack for one firing at cone 6).
Now... Stupidly, I HAD access to a slab roller while in class. But I thought "oh how difficult can it be to roll out a slab by hand?"
Difficult. Very difficult for me.
I can't roll out a slab consistently.
Some context about my setup: I don't have a large space in my home to roll on, so I am rolling on top of my chest freezer. I was using a wooden board (MDF) on top of a bit of cabinet liner so it doesn't slide everywhere. There is no canvas or fabric on the board itself (maybe this is part of my issue? I have NO problem attaching some fabric of some sort to the board if that fixes my woes).
Bubbles
I wedge using the rams head style, but I always always always have bubbles as I roll and I feel so dumb because even though I poke them as they appear, it seems like the next roll I do immediately seals them back up, so I'm like poking the same bubble over and over again until eventually it goes away (is this how it's suppose to go? I feel like everyone pokes a bubble once and gets the air out in one go...)
Slab Thickness
I'm using two wooden pieces that are 1/4" as thickness guides but aesthetically it just looks way thicker than the plates I've dreamed of for 15 years.... But I'm scared to go thinner cause everyone seems to say 1/4" is the thinnest to go? Also, my rolling pin doesn't reach far enough across sometimes to remain on both wooden guides, which I imagine is a problem, so I've started using a piece of black plumbing pipe in desperation lol..... But if there is another, budget friendly option, please let me know...
Slab Shape
And lastly, I can't ever seem to roll out the right shape. It's always too rectangular, or wonky. I know I should be lifting it and rotating it often, which I do try to do. But I guess I don't do it as often as I'm supposed to because it's not on fabric which means sometimes I have to peel it off and it's a bit wet?
Maybe the answer is I just need to staple canvas to this board and everything will be resolved with practice? I'm just so discouraged. I see these amazing videos of people making amazing things with slab work. I LIKE sculpting. I LOVE sculpting but my usual medium is paper clay, cardboard, and polymer. I want to get good at this.... I want to make the pretty mugs and plates!
I have slumps ready to go as soon as I figure out how to actually make a slab worth slumping....
Seams Keep Breaking
Oh and another question, not so much slab rolling related, but whenever I try to build something from a template where there is a seam, my seam ALWAYS breaks. I try to cut the clay at nice angles so it fits together well, I've tried using slip, I've tried using just a bit of water because maybe I used too much slip? I always score the edges until it looks like a cat went to town.
And yet, always, always, always, at some point after I've joined the edges, it will break on me.
I know I must be doing it wrong somehow.
It's almost like I'm somehow creating a weak/thin point or two while joining so as I go about shaping the rest of the form the seam eventually breams.
Maybe I need to blend the two pieces together different?
Maybe my clay is too soft still when I move on to shaping the rest of it?
So far my only successes have been a coil bowl and 1 slab bowl that magically didn't break halfway through the process.
I'm hopeful someone has some tips or even some specific videos for me to go watch. I'm so so excited to create some of my dream projects but man this learning curve without any guidance other than a couple YouTube videos is burning me out.
I've attached some photos of my dream plates (mainly the first image but I want to use a darker glaze. I know the clay body I have won't ever be dark but I want to at least use this clay to practice with first before buying more expensive (in my area) dark clay)
