Expanding

I made some pots at Higher Fire, for that is the studio Child and I chose to join. I was pretty torn, but he was clear that he felt he could create there, and, well. Reduction. Who can resist those copper reds?

I have my coloured porcelain slips that I wanted to test on the local clays. I have a few new texture tools. I have a pint of sodium silicate. Off we go!

I'm afraid all the photos in this post are pots in their greenware state. That's because none of my pots have made it past the greenware state yet.

 This one is pink and orange slips on Black Mountain clay:

 Yellow and teal slips on Black Mountain clay:
 Blue and green in back, purple and yellow in front. Both Black Mountain clay:



I was going to go in and trim those, but Child got ill and I thought I had better stay close to home. Here I've switched to B-Mix.  I had some cardboard shapes cut out already, so I am testing the sodium silicate and slip combo with a broomstick pot and a slab pot. Here they are with shapes, slips, and sodium silicate, just waiting to be dry enough for processing.
 The pink and red one got touch-dry first.
A light roll starts the cracking and reveals the shapes. The making of these shapes is the best use for Child's empty cereal boxes.
 Expanded yet more with increasingly large dowels. Because I'm rolling from the inside, the cracks are not getting deep here. They compress under the pressure of rolling against the table.
 Going oval. Because I can.
 Off come the cut-outs. Because there was no sodium silicate under, there are no cracks under. There is also an exposed spreading area around the cut outs with minimal cracking.
 A rolled slab for the base. I set the pot on it and traced around with a needle tool.
 Turned over, a little water, and tapped (pounded) into place with a rolling pin.
 I do like feet on things. Three feet are unlikely to let the pot wobble.
 I do like a rustic look to my pots. But you knew that.













Just waiting to dry now. Once fired, I will be ready in case anyone sends me Valentine's Day flowers. Gotta plan ahead.



Ah, but what about the rolled out one? Slips are blue, teal, and chrome green. I rolled in all directions to keep the cracks from being overly directional. The cardboard cutouts split when soaked for so long.




 I did take off as much of the underneath layer as I could because no one wants to smell that burn. But it's only a tiny bit left now.
 Foot rails, and a bit of drying while inverted over a water bottle.


Now it's just got to dry and be fired. I think I'll glaze this one all clear so it can be used for food. Celery sticks. Cupcakes. Something.




And that is the state of the expanding clay as of today.

Silence?

Why the months of silence? I'm packing up the pottery, the house, the whole life, and plan to resurface in California some time later this year.

I do have a few projects left to do here. Even more to do once I get over there. Patience, please. It's not over, just in transition.

It's a learning thing: clay gun hollow dies

Some time ago, I bought a clay gun from Top Pots. It's a small, hand held thing, but it's good for small jobs. It came with a set of dies, but none of them were hollow dies. My metal working is not up to scratch, so I had a go with a material I know. Clay.

All of this is very seat of the pants and trying to learn a little each time. This is just my first attempt. Mistakes were made. Successes were had.

My main concern was whether the dies would stand up to the pressure of the plunger. I used Valentine Clays B17C-grogged stoneware because it's what I happened to be using for a different project at the time. I rolled out slabs and marked circles with the end of the clay gun barrel. I cut slightly larger than the mark to account for the shrinkage of the clay.

The inner shape is set back a bit, not flush with the outer ring of the die. The clay has to go around the supports inside and re-join on the other side, so this, I hope, will give it a better chance of doing that.
 I'd just reclaimed some terra cotta that was stored outside in a bin for a few years. Not the nicest of clays, still sporting a few small bits of leylandii. Some of the failures might have been down to that.


 I started to push the handle, and waited for the loud crack. Or the quiet crack. No crack. Just clay coming out in a tube.
 Several tubes, in fact. Not long tubes because this is a clay gun, not a giant motor-driven extruder. It only holds a small amount of clay.
 And lookie there. Intact.
The successful die poses here with its progeny.
 So I tried the square one. Alas, the fit was not so good. It was hard to screw the end cap back onto the barrel and have it stay attached during extrusion. It took some force to wedge the die down into the cap, and the cap blocked the corners a bit. I found that it had shifted a little (in firing no doubt, I couldn't have made it wrong, right?) so that one of the four sides was thinner than the others. Live and learn.
 But it wasn't a total loss. The die was hard to get out again, but it did come out with a little gentle leverage from the front.

 Once removed, the square could be trued up again with minimal effort. The die seems completely unharmed, and taught me some of the things to avoid when I try again.

There is one more die I made, but I'm going to try it another day. Possibly with nicer clay.

Paperclay patches on bisqueware

Several months ago, I wrote about paperclay patches, mostly on greenware. In that piece, I made mention of using paperclay patches on bisqued work as well, but didn't go into much detail.

I recently had a group of kids (and some of their parents) over to play with clay. Alas, someone made a piece that exploded in the kiln, taking two pieces of kid work with it.  Disaster!

Young artists do need to learn that sometimes things happen, sometimes things don't work out, but this was not to be one of those times. I seized the opportunity to both save their work and show you what I was talking about.

The slip itself was made of a 12-egg carton (post egg), water, and roughly a litre of the same clay I intended to join. In this case, we used terra cotta. I used the stick blender to pulverize the slip quite well, but I didn't sieve it or anything like that.I just ran my fingers through it to be sure it felt smooth.

The flat man (something from some computer game I know nothing about) had a fairly clean break right across the eyes.  I dipped both halves of the break in the paperclay slip and let them dry slightly before smoothing over with more of the slip. The man is pretty delicate at this stage, so I put him on a cardboard bat to minimize stress on the join until he got into the kiln.  I treated the join on both sides, letting it dry a bit, then adding more as the drying slip receded into the hairline gap.




Also a casualty of the shattered piece was a turtle. Both the front arms came off, and none too cleanly.

Again, both sides dipped in the slip, then smoothed over the outside a few times to make the join stronger.



Although I have occasionally used this patch technique on my own work and glazed the pieces straight away, I decided to re-bisque these. The creations of children and beginners gets special handling over here. Raw joins are just too delicate for beginning glazers.

I think it's probably best to re-bisque, even if not strictly necessary.



After being re-fired, the joins are vaguely visible to those who are looking for them, but the kid who made this had no idea it had broken until I told her later, after the finished, glazed piece was in her hands.



Both the turtle and the flat man benefit from being fairly rustic in their intended surface. It is possible that my joins here are actually too smooth be part of the original textures.Perhaps there is enough natural variation that I was able to get away with it.


Here is the back of flat man's face. The join is a bit more obvious here if you're looking for it, but it was not a problem for the artist, who was glad it had been given a second chance.

If I had been patching pieces  with precise and smooth surfaces, I would have taken more care to build up a slight excess and then sand the join down again post-re-bisquing.

Once glazed, both pieces had the ring of an intact pot to them when struck with a metal tool, not the dull thud of a cracked piece.
 This is lovely. I would never look at this and wonder if it had ever been shattered into multiple pieces. Our little secret.


Flat man is all set to be displayed on a wall somewhere, ready to do ... whatever it is he's meant to do.  His maker is very pleased with the results.







I can't promise this technique will always work. Clay can be fickle. There are times, though, that it's worth having this trick in your arsenal, just in case there are no other options.

All Saints for Christmas

I've just had my acceptance notice for this:

Anglian Potters at All Saints, Jesus Lane, Cambridge
This selling exhibition runs from Saturday, 17th November (mulled wine and mince pies between 12 noon and 2 p.m.), and closes on Sunday, 16th December.
Opening times: Mondays to Saturdays 10 a.m. to 4 p.m.
Sundays 12.30 a.m. to 4 p.m.  

There are usually 70-80 potters participating in this, so it's a great chance to see a broad sampling of what clay can do.

I'm heading out to the studio now to work on a commission. I wonder if any new ideas will happen while I'm out there.

Is there anything you especially want to see from me when you visit this show? At the Ickworth Wood Fair, one woman told me she had gone to the show last year to top up her game piece collection, but I wasn't participating that time.

Dragonfly

This morning we drove the the Wayland Dragonfly Gallery in Watton, Norfolk to drop off some Face Plates for an upcoming show. Everyone was very nice and helpful in providing what I needed to make it all look good.

So now if you can't make it to the exhibition, you know what of mine you're missing, and if you see something here that you must have, you know where to buy it!


The plates on the lowest surface are in the vicinity of 11" round. The small one at the top is about 6.5" round.

It looked like some really interesting paintings were going up in other areas.
