Cone Breaking During Firing?

12 September 2013 - 08:33 AM

My cones are breaking during firing - they aren't breaking all the way through - at least not yet. 

 

The first 8 or so firings with the kiln were fine - no breaking of the cones. Then it started last week the bisque fired cone had a small break in it - nothing major. the glaze one had a bigger break in it and now the bisque from yesterday has an even bigger break.  I thought it might be the supports and sticking to the supports so I flipped them over assuming that nothing had been sticking to that side yet so it might fix it.. but it didn't. So I am planning on getting new supports. 

 

As I have been googling around like crazy the only other thing I can find is it might need a new sensing rod/tube.  From what I can find the rod is supposed to move freely in the tube - I am not sure I know what their definition of "freely" is . The rod moves up and down just fine - it moves to the left side just fine - the right side it doesn't seem to want to hang out... but overall it is in the center of the tube and when it goes up and down it is in the center.  Could I need a new tube?  I have never replaced the tube/sensing rod so I have no idea. It is a used skutt 1027, I thought she said that it had been replaced recently.. I know the elements are new in it. 

 

I am just not 100% sure what it could be. I figured I would start with the support rods and get new ones of those... but I am a little hesitate to do a glaze firing and have the cone break and then ruin that firing. I have a festival coming up that I really can't waste pieces on with having them not firing properly :(  If anyone has had this issue or has experience with this and has some advice that would be amazing! 

 

Thank you so much!

 


Vibrating Brent Wheel

05 April 2013 - 07:42 PM

Hello!

I am very new to the forum - excited to be here!

I have had a Brent No2 wheel for about 5 years now and done pottery on and off. I am now really trying to get into pottery. The first wheel I had was replaced after about 1 month of having it since I could not center on it for the life of me and it was the wheel and not me since I was taking a class and could center on their wheels no problem. Sent it back to Amaco, they said no one could center on it and sent out a new one. It has been through a couple moves around the house and then one big move when I changed houses.

As I am now getting back into pottery every day it just keeps vibrating. If I put tools on the head to just rest and turn the wheel on low the tools will literally vibrate off the wheel. The metal catch bin that sits in the holder will vibrate off the holder if I do not place a couple rocks in it to weigh it down. It seems like it is just getting worse. I was trying to foot a pot tonight and I couldn't get it tapped center for the life of me. I finally got it on center, put clay around it so that sucker wasn't going anywhere and within 2 spins it has vibrated itself out of the clay around the base.

I have never tried to fix a wheel or know much about how to fix one. It is on concrete and on level ground. Anyone have any ideas what could be wrong with it? I have never worked on a wheel that vibrated this much and it is really making the whole process of making a pot rather difficult since I believe the vibrations are making the pot go off center at every chance.

Any help on this would be amazing!

Thanks!
