How to Throw a Pot/The Zen of Pottery

Step 1:  Slap the clay onto your batt or wheel head as near to center as possible.
From my very first pottery class - age 17
Used to be a set of four.
These are old, chipped, and headed for the trash.

Last week I happily sat down at my pottery wheel with a full ware-board.  The previous week had been unusually productive.  I had a large bowl (one of the biggest I've ever made), a small berry bowl, (holes already punched) and a garlic pot and lid.
This class, I would trim and finish the bottoms then put them on the shelf to be fired.

A new girl sat across from me.  She said it was her first time using the electric wheel.  She couldn't figure out how to turn it on.  I offered to help and jumped up.  I noticed the powerstrip was turned off.
I flipped the switch.  My wheel, of all the electric wheels, just happened to have been left turned on--with the foot pedal pushed to full speed.

Step 2:  Center the clay.  Root your left hand firmly and use both hands to bring the clay into a cone shape.  Not too skinny!
Hand-built spoon rest.  I actually like this piece.

My ware board went flying.

Fragile greenware pots went crashing to the floor like Oaxacan fritter plates*.  Only the small berry bowl survived and I was lucky to keep that one.

When I taught in Misawa, I told my students time and time again to make SURE their wheel was turned OFF before turning the power source ON.

After screaming like a little school girl, I shook my head, swept up the pieces, and started over.

(The girl across from me--appalled--kept apologizing and looked like she was going to cry.)

Step 3:  With your left hand firmly rooted to the left side of your clay, use your right hand to form a truncated cone.
One of my favorites despite the pin-holing.  


This is where I keep the Dove chocolates
Why do I like pottery?  I have no idea.  It is such a volatile, unpredictable process.
Even experienced, full time potters will tell you never to get too attached to an unfinished piece.  There is just too much that can go wrong.

If you're having an "on" night, and your throwing is flawless, you still have many more chances to lose your "perfect pot".  Which, by-the-way, there is no such thing.


Step 4:  Repeat previous two steps until clay is centered
A gift for a friend.  I HATE how this glaze turned out... 
...So I'm making something to replace it.
We'll see if I screw this one up too.

{Handmade pottery is never perfect.  Even when thrown on the wheel a "perfect pot" will probably be a tiny bit uneven, a tiny bit off-center, or have a tiny flaw in it somewhere.  The key is to not look too close.}

But let's just say you do throw a perfect pot.  What next?
The next step is to let it dry a little.
     But not too much.

You want it to be leather hard.  Hard enough to hold it's shape and withstand medium pressure, soft enough that the clay you trim off will fall in perfect little curls.  Definitely not bone dry.

You cover it with plastic and put it in a "damp cupboard" for a few days.  How quickly it gets to "leather hard" depends on the humidity and how well it's covered.

Try not to bump it when you put it in the cupboard and be careful not to squish it with the plastic.

Step 5:  Drop the hole and compress the bottom.

Two little pencil jars with underglaze.
I like the one on the left.  I keep the one on the right out of pity.
When it's leather hard, you can trim it.  This is the part where you fix the bottom.  The goal here is to get rid of excess clay, refine the shape, and add a "foot" for a finished look and so it will sit flat.

Obviously, this step leaves lots of room for ruining your pot.  Leave too much clay on the bottom, your small mug weighs five pounds.  Take too much off, you can cut through and end up with a planter or a bottom that's too thin.  Trimming is a delicate, sometimes vexing, art.

Step 6:  Pull your walls.  You're aiming for a consistent 1/4 inch thickness all the way up.

A Raku piece with glaze applied too thinly.
Needed more flash on the outside too.







The inside crackled really nicely though...
But you've done it!  Your pot has been trimmed and can now be fired!  But wait...not too soon.  If it goes into the kiln even the tiniest bit damp, the trapped moisture will turn to steam, force it's way out, and in the process...BOOM!  No more pot.
And no more neighboring pots.
And the owners of those pot causalities will NOT be happy.
This has happened to me.
...and I was not happy.

But say your pot makes it out alive.  Now it is considered Bisc or Biscuit ware.  It's still breakable, but MUCH stronger.

Now you get to GLAZE it!

Step 7:  Refine the shape and lastly, trim the top.

Before leaving Japan, I gathered up all the pottery in my house.
A few things I kept, many I tossed.
The rest I pawned off on anyone who happened to stop by...
Meet my arch nemesis:  Glazing.

It seems so easy!  Dip the pot in glaze, fire it and VOILA!  Perfect pot completed!!!

Step 8:  Carefully remove from wheel.   You've thrown your first pot!   
Including our Mamasan.  She said she'd use the green bowl for her rice.
We miss you Eiko-san!!!
Except...

You can't put glaze on too thin.
     No lustre.

You can't put it on too thick.
     It'll run and puddle at the bottom.

You have to get the glaze recipe and kiln temperature just right or the glazes will be under developed.
Or over developed!
Or you might get
  pinholes/
    crazing/
      shivering/
        crawling/
          creeping/
        blisters/
      or settling-out!!!
(No, I'm not making this up.)

And if you want to put multiple glazes on the same pot, well, you're taking all sorts of chances.

Glazing is the step where I lose most of my pots...to ugliness.

Some pots turn out "okay".  But almost every single pot I've ever made has had SOMETHING I'd want to fix or change if I could.

None are perfect.

And yet, there is something therapeutic and, dare I say zen, about the whole frustrating process.  Something about combining creativity with messy earthiness with control and lack of control and spontaneity and luck and chance.  And the possibility that the NEXT pot you pull out of the kiln will be your best pot ever.

Hasn't happened to me yet.
But I have a good feeling about my next piece...!

Class meets Thursday night!  Care to join me?

Hope you're enjoying this one Liz Brazeau!


*I put some effort into this completely random and obscure simile!  (Max and I just learned about adding simile to our writing.)  But this is what I thought of when I looked down at all of my precious pots in pieces littered at my feet:  When I was very small, (6 or 7) my family took a trip to Mexico over Christmas.  One vivid memory (of many from that trip) was of ordering a yummy crispy cinnamon dessert.  When we were done eating it, we took the clay serving dishes outside and threw them against the brick wall along with everyone else.  I had to try a few Google searches to find evidence of my fuzzy memory, but found it here six paragraphs down.
I love Mexican Christmas traditions!  This is one reason we have Mexican food every year for Christmas Eve!

Evolution of a Pinch Pot Snowman

I saw a really cute snowman on Etsy and decided to see if I could turn it into a project for Homeschool Pottery in December.
So working from memory, I made this guy:Not cute. Kinda creepy.
I tried again changing the proportions:
Better, but still "eh...!"

Later, I made another one with my students adding a "pickle nose" per Samuel's instructions.
(From a favorite Snowman story book of Miss Judean's.)
Getting cuter!

(Both arms have already been glued back on twice. I'm thinking next year I'll just poke two holes and use real twigs that can be removed for easier storage.)

Finally, I looked up the original and copied it almost exactly:
Now THAT'S a cute snowman! Thank you for the prototype, Etsy potter! (I promise not to start selling these!)

Pinch Pot Turkeys

Made these as examples for Homeschool Pottery in November.
The body is a pinch pot placed either upside down or right side up. I learned not to make the feathers too thin or they broke off...repeatedly.
The kids did a great job and amazed me with their cute and creative turkeys!

Homeschool Pottery

Every Friday, I load Gabe and his booster into the car and head to Arts and Crafts where I teach a Pottery Class for Homeschoolers. (We have a lot of kids on base who Homeschool!!!)

I've been doing it for quite a few months now and the same old projects were getting a little boring for the repeat students. (And especially for me.)

So last month I decided to shake things up. On the regularly scheduled "pinch pot" day, instead of making plain little bowls, we combined two pinch pots and made Halloween Jack 'o Lanterns.
(As seen on "Art Projects for Kids"--one of my favorite blogs ever.)

I loved the results so much I brought my camera in to take some pics. Yes, I'm the only one excited about these pictures. Sorry. Pregnancy is making me a boring blogger. Anyway, here they are:

This month, we made Pinch Pot TURKEYS!!! I know! You're dying to see them! I'll be sure to post pictures when they're finished!!!
