In Topic: Does Firing An Electric Kiln With All The Plugs Damage The Elements?

26 June 2014 - 06:46 AM

Our club kiln recently had to have an element changed after not many firings. The person who mended it said that it was because one of our members had been firing with both peepholes covered right from the start - no venting.


In Topic: Foot Rings And Puddles

26 June 2014 - 06:41 AM

I have copied an idea that I saw on a range of plastic containers on sale in Australia. I turn the bottoms flat and mark where the foot rim would have been. Then I stick on small balls of clay, evenly spaced along the marked line. To get the little balls the same size, I extrude the clay from a clay gun and cut equal lengths which I then roll into balls on my damp palm. My computer will draw regular shapes of any number of sides. I print them and cut them out to use as a guide for the placement of the little balls.

Top each ball with a little dab of wax emulsion, and the bowls and cups are ready to raw glaze.


In Topic: Sitter Shutting Off One Cone Before Supposed To...

25 June 2014 - 10:57 PM

Here is a quote from the instructions given by the manufacturer of Paragon kilns: 

"The cone used in the kiln-sitter will not react to heat in exactly the same way as a cone placed upright in the normal position. The weight of the actuation rod and the horizontal position will cause it to bend at a lower temperature than an upright cone. It is usually necessary to use one cone hotter in the kiln-sitter than the cone to which you wish to fire."

To Chris Campbell,

I am using a front loader and my heart yearns for a top loader. I had a gas kiln that top loaded and it was much easier to position the shelves because I didn't have to hold the shelf out in front of me. It did have brick walls on which I could rest my weight. Another disadvantage of the front loader is that you can only see the setting from one direction. On a top loader you can see it 300°.


In Topic: Chamois As A Batt Securer

29 May 2014 - 11:00 PM

In Australia, fibre cement is a common building material. It really sucks the water out of clay. I have been able to secure bats made of this material to the wheelhead with only slip. The material has a smooth side and a rougher side and when placed rough side down onto a puddle of slip, it stiffens the slip into a leather hard sliver of clay that is moulded to match the underside of the bat. So long as you don't allow water or slurry to get under the bat to soften the clay back to slip again, the leather hard layer will resist a lot of sideways movement.
