Throwing - out of center - why?

Hi

Okay - I have started throwing on my wheel again. But I keep getting these LUMPS of clay that seem like they are weighted on one side, even though I have spiral wedged them for at least 10-15 minutes before splitting them up into about half-kilo pieces, making those into balls by slapping them - and TRYING to get the things centered.

This is getting really annoying, and I wonder if any of you understand what I mean and have some kind of way to cope with the problem.

Looking forward to some replies. I am not going to go near that wheel for a few days now, since it is just getting me annoyed.

Hi Bubbles, does this happen when centring ? or when you are opening up ?, or maybe pulling up the clay?? It could be you are moving your hands too quickly to the clay or away from the clay, try smaller lumps of clay to warm up with first, I find a warm ups works for me and it is relaxing when not aiming for a specific shape. I hope this helps, don't give up, Yours in clay art Elaine.

Hi Elaine :-)

It is happening as I am trying to center. It is as if there is a blob of heavier clay on one side of the piece. I am sticking to pieces of about 500 grams still - that is around a pound, I think! Not very big. I am still at the stage where I kind of go where the clay leads me. I try to pull up into a cylindar and then work from there.

I am going to video tape this in the near future and post it to YouTube, so people can see what my problem is. So difficult to explain in words!

I am very careful about removing my hands too fast.

Hi Bubbles I will look forward to seeing the video, it may give a bit more info that way as to what is going on. The other thing I have learned over the years of potting is to show the clay who is boss. Also, as you know it must be really be cantered before opening the clay and pulling up.

a friend of mine had a similar problem & we discussed wedging, arm bracing, etc. it wasn't until she brought over her plastic bat that we saw the problem. her injection molded plastic bat had ridges in the underside that put a quiver into the pieces as you'd try to center it. she threw away the bats, got clean old flat ones & the centering problem went away...

Hi,

I have seen this happen when the clay is too firm. Try using softer clay - not so soft that it is sticky - it might be that you have to use clay that is too soft to pull up into really thin walls at first but as you become more used to centering you will be able to deal with firmer clay.

I found that I had arthritis a few years ago. The pain was excruciating. First doctor prescribed pain killers that did nothing, the second opinion came from a friend who is a doctor that specializes in immune disorders and he told me to try Glucosamine. I can't tell you how well this worked. I recommend that any potter or person dependent on their hands pass the age of

40 consider it as a supplement. It keeps your joints from degenerating and helps out once they do.
