Lesson 2: Ball & Socket

Lesson 2 Ball and Socket

 

Now that we have got pancakes, snakes and balls down,

let’s work on putting them together into slightly more horizontal forms. We can keep them on the pancake base but eventually, as the students get better at technique, some things won’t have to be on that.

 

Dinosaurs, Dragons and other Four-legged beasts

It’s always good to start with animals with naturally thick legs like dinosaurs, elephants, hippos and rhinos  ( as opposed to horses, camels and giraffes –I usually encourage the kids to make those last 3  “lying down”–kind of kneeling with their legs tucked under, as animals do)

For Dinosaurs and dragons and other small-headed, long-necked animals:

The first thing to convince the students of is to make the head, body and tail all one piece.  This is that “yam” shape that is really just a snake that ate an antelope! it is pointy on the ends and fat in the middle.

It helps to pinch it into the general shape firstthe-yam-shapethen roll it smoothyam-rolled-and-smooth

show the kids through example and then by placing your hand over theirs that they can hold their hand at a low angle to the table to achieve that point at the end. showing-how-to-roll

Once you have a good strong yam, poke 4 holes into it

4-leg-holes

Roll 4 fat short coils or 2 coils that you then cut in half. Put those points on one end and tap the coil on the table to make the other end flat and wide just like a dinosaur or elephant foot.

Make sure they understand scale- that is, tiny skinny legs won’t hold up a big fat dinosaur, nor will giant tree trunk legs go into the holes you poked in the body.

4-legslegs-in-place-before-smearing

Once the legs are firmly in there, encourage smearing- I say “erase the lines” but still, the concept of bonding the clay together is often difficult for them to grasp. As it is a key part of making the piece strong, it is worthwhile to spend a little time on it. I’ve tried saying “smooth the skin” and pointing out they don’t have lines on their skin.

You can even take their finger and use it as a smearing tool and they get a better understanding of the sensation and result.using-students-finger-to-smear

Now you may turn your dinosaur right side up and bend the neck and tail to look more realistic. 

define-head-from-neckNOTE: I highly recommend curving the tail and especially back toward the body. This will make it stronger. Any time you curve the clay, it is stronger.

They can poke holes for the eyes- I always show eye sockets and I achieve those by facing the head away from me and pushing the clay back towards me with my finger.making-the-eye-socket(sorry, a bit out of focus)

You can also “open” the mouth with a plastic knife or skewer.making-rexs-mouth

At this point, more slots or holes can be made in the back and even tail to add spines or plates (as in the case of a stegosaurus)

ready-for-spikesa spike should look like this:making-a-spikelots-of-spikes

 

If you feel the legs are not well attached or the tail is too thin, or even that the head won’t stay up, it is time again, for the pancake. The dinosaur can “graze” or check a nest of eggs and therefore have its head down and touching the pancake and the tail also should touch down and end within the boundaries of the pancake. student-work-other-view

solution: fresh clay- encourage students not to work the clay too long. It gets dry and cracked.

You can take the “old” clay, dip it in a water and stick it in a sealed plastic bag. It should absorb the water it collected on its surface and that should be sufficient to re-hydrate it overnight.

too-thin-a-body
Too thin a body doesn't leave room for leg holes. Encourage the student to roll only at the ends and not the center.

 

This comes from vigorous rolling at just the very end. At this point, you will need a "clay bandaid"

The "clay bandaid" is a wonderful fix-it for many problems where the clay has gotten too thin. This is frequent as students squeeze the clay in an attempt to fix it but it only gets thinner. Add the thin flat piece and have the student blend it in. They love the name.

Students tend to think of bodies as having a lot of separate parts. When they construct them this way, they are much weaker. Plus they often don't blend them together. This is a very weak piece.

For short tails, they should always be pressed against the body so they will not break off.

REMEMBER: Any thin clay sticking out, especially straight out, is very vulnerable to breaking off and should be avoided.

T-REX

T-Rex is a special case. It is an immensely popular dino and as such, deserves special attention.

He is a tricky beast as he is much more upright and his big, toothsome head  makes him top heavy.

This time your yam should end bluntly at one end. 

t-rex-yamYou must “choke” him a little to define his head.choking-the-neck-to-define-the-head

Then make two “ice cream cones” and flatten them somewhat.Now here is the tricky part, you must actually pinch out a kind of peg from the side of the fattest part- this is the upper thigh.pinching-out-a-peg-on-the-leg

 Make holes on either side of the yam and stick those pegs in

hole-for-leg-pegt-rex-with-unbent-legs

bend the ends of the legs into feet and curve the tail so he can stand up. (I’ve started on his face here- 

bend-legs-and-tail-to-stand

But take the time to  smear part of the thigh into the body to keep him strong.

smeared-legFor the feet, cut a notch in the pointy end- this gives you your two toes. Don’t make them too delicate. 

making-the-toesNow you may make the face, make nostrils and  eye sockets as described above and put little balls in and poke a hole in the center. To make him look angry, you can push the brow down a little, this also holds the ball in better.

Now, open a large mouth. It’s good to have a pretty fat head so the lower jaw is quite thick. Now you can poke holes around the entire perimeter t-rex-dental-surgeryholes-for-teetht-rexs-teethand insert tiny tiny pointy coils for teeth

. The danger here is that the kids spend too long rolling these and they dry out quickly and crumble. Encourage them to roll them quickly between their fingers and also you can put a little water to soak into the canvas mat and then the mat will absorb less water from the clay.

the mouth can actually be opened wider to accept the teeth teeth-installedand then closed to interlock the teeth- again, this makes them stronger. The teeth will poke out every which way giving him a snaggle toothed look. The students love this!

Now you can poke two holes in the chest,

Handbuilding Weeks 5 & 6

Yes, yes I got behind! But at the end there is a bonus of a workshop I did of inlaid slip into Terra Cotta Pavers

 

Handbuilding Week 5 

Darting  vessels and adding clay into cuts

Okay so I’m really hooked on the brayer as a method of sealing the clay onto itself.  Darting is where you cut a slit or a leaf shape or a triangle out of the piece and close up the gap to change the shape of your pot.

Darted Tall Pitcher

I made a basethe-base-b4-darting

and darted it at the bottom. Where I wanted it wider, I slit it, spread it apart and added a triangle of clay. any time I attached clay to clay, I thinned it so the walls would basically be the same thickness all round.

Here it is, awaiting a triangle of clay to be added.base-after-darting-bottom-and-opening-top

In retrospect, I wouldn’t have darted it down there. I think it made it a lot weaker. Where I wanted it narrower, I cut slits and folded them overlapping. After I got the base attached, I darted in the top part and then added several more tiers. You can see on the right where I’ve made a slice and will thin that and then fold it in to overlap and make the opening narrower.

adding-the-next-tier

I just kept adding wide strips of  slightly hardened slabs and finally added a handle. The piece turned out quite tall. 

Then I scored and wet it a bit. To press it together, I used a brayer which gave me a great surface quality.

I supported on the inside and went over the area-to-be-joined with a brayer; pressing it down and bonding it together.

I also used the brayer at a slight angle on either side of the handle.

and Voila! a huge piece!

Darted Bowl

This is a great and simple project. I took a circle and made 4 cutscircle-with-4-cuts

I brayer-ed the edges to make them thinner so they are less likely to have the strength to warp away from the joint and also to have a consistent thinness throughout the bowl.brayer-ing-edges-2b-thin

Then I fold them up and overlapped them.

Added matching feet and there I have a nice serving bowl. The white mark is the slip that I put my signature on.

the feet have the same casual look and construction to match.

HANDBUILDING WEEK 6

Faceting, slip transfer, sgraffitto

 

Faceting a vertical vessel

So, you can get springs in all shapes and sizes from, say,  the back of a spiral notebook to the inside of a ball-point pen. It’s a good idea to stretch these out a bit as too tight a coil has too high a profile so the clay gets caught in the narrow spaces between the coils in stead of cutting cleanly through.stretched-spring-wire-springabove is (from bottom to top) a spring that has not been stretched at all, a regular wire (you can also use a cheese cutter )for flat cuts and that same type spring all stretched out and ready to use.

Start by making a very basic vessel. I just shoved the end of this dowel rolling pin into a rectangle- it could be a round shape.beginning-vessel-to-be-faceted

After I opened it a bit,rolling-a-little-to-open-the-vessel

I took the stretched out fine spring that someone got at a resource center and cut in various ways down the thick walls.

beginning-the-faceting-cutAt one point I cut all the way through but I just reattached that and re-cut it shallower.

 

You can change directions with the wire or let one end curve ‘round to make a dynamic pattern.

Transferred Slip Design

Another thing we tried this week was transferring slip.

I threw out a slab of stoneware and then covered it with white slip.

Then, using black slip, I painted a tree on a piece of newspaper and then pressed it onto the slab.slip-transfer-just-b4rubbing-it-onpulling-off-the-newspaper Not all the slip stuck but that gave it a cool texture and look.

I plan to build a house like box with this slab. Remember my shadows of trees on buildings entry? (here)

For my last demo, I gave a quick lesson on sgraffitto since it is the main kind of work I do. I painted the surface with slip, drew an image on it and carved away all the negative space. You can see photos of this on my “How to make a Picture Vase” entry.

 

After class I taught a Terra Cotta Pavers workshop. They came out so great that I took pictures and thought I’d add that technique to this entry.

Inlaid colored clay

Start with two  contrasting colors of clay; in this case I wanted to inlay high fire white into Terra cotta. I had students draw life size pictures and then lay thin coils of the white clay over their drawings. This even worked exceptionally well for a 4 year old & mom team.* note if you do words, lay them out in mirror writing or they will be backwards!

After you have your pattern laid out,face-beforeput a fairly thick pad of clay over the coils. These were extra thick as they are meant to be garden pavers (stepping stone type things). Once they are in place, pound the back evenly with your fist or the flat of your hand. You may also use a rolling pin.

Then just flip them over!inlaid-face-afterIt’s hard to make a bad one!

Lastly, I have added “after” photos to several entries as I’ve gotten the pieces back from the glaze kiln. Check out how Inlaid Slip turned out!
