  1. That's a good idea, I like it. I do have a heat gun I could use for that. I needed 6 cylinders 16 " long for the rim of two pots and 2 22" long for the base of the pot to attach my feet to so I was a little impatient to wait for them to be strong. I reduced the size and increased the thickness in the clay to 1/2 " and had much better luck with bending them into arc's. Now i'm onto working on the feet
  2. Thanks . I am tempted to put a pin hole design all along the rim so I dont have to worry about it. These pots will end up being the only thing in my kiln because they are pretty big so it would be nice for it to succeed. I get pretty bummed out when I ruin everything in a load from some blunder
  3. I have started a new project using my extruder and have never used the hollow dies. My first extrusions were too flimsy so I deduced that they were to big in diameter to work for my application (the rim of a large flower pot). I didn't want to waste the clay or go through the trouble of drying it to reclaim it so I wedged the extrusions and put it back in the extruder. As a result some of my tubes still had a few holes in them. I plan on poking holes in the interior of each rim tube and slow bisquing. This is cone 10 black mountain clay should I be concerned that it will still blow parts off in the firing (bisque or glaze?) I wanted to once fire them actually and now I'm a little scared they will blow up so I thought I should bisque them to make sure they will be able to handle the cone 10 firing. I dont' want a mess to clean up in my kiln. Your thoughts and experiences would be appreciated. Thanks
  4. Thank you for the response . Now that you mention it I do remember reading archives on Clayart from others who have converted an electric kiln saying that the kiln won't last long. That must be why. I will check out the European Union standards before using the RCF, thank you. So should I not worry about the exterior of the kiln, just insulate the tope and the bottom?
  5. that's a good question, I shouldn't need one for an updraft kiln should I?
  6. I'll be firing to Cone 10, I used to fire to cone 6 in it but it was rated for cone 10. I plan to use natural gas. It has an extra ring on it that I thought about making a pully for so I could use it for Raku some of the time. It will be exclusively used by me but I've never fired a gas kiln myself so I am a little timid about it. If it is a 3 1/2 cubic foot kiln how tall should the chimney be?

  8. I have a old electric kiln that is only 2" thick and I have already purchased a gas conversion kit. It is an updraft kiln design. I would like to do reduction firing in it with slow cool downs. Can I put ceramic fiber on the outside of the kiln and then dry stack hard brick around the outside to insulate it? Would that be enough for slow cooling? I have about 900 hard brick from an old beehive kiln that I'm trying to find a use for...
