  1. Kiln Within A Kiln?

    I am an over-extended hobbyist with a 7 burner, 27cf updraft gas kiln that doesn't get fired very often due to the shear volume of work required to fill the thing! I have been able to get good reduction results, as well have enjoyed glazing and single firing green wear. I am finding it difficult to make much progress with my glazes with the limited frequency of firing. I have thought about some sort of co-op arrangement, but am hesitant for a variety of reasons... So... Has anyone ever built a temporary test kiln within their larger updraft kiln? I was thinking small box, 2 half-shelves, utilizing the one central burner, a shelf as a damper. Some logistical concerns... If firing with main door closed, excessive heat accumulation within the main body with subsequent inability to adjust the damper or monitor cones. Any negative impacts of firing with the door open? Fumes (it is outside...)? Other considerations? Is this just a bad idea? As well, if I should give a partnership/co-op some more thought, tell me about a success story. Thanks for your feedback! Brian
  2. Feeling The Need To Share My Shino!

    Wax resist streaks. Cone 10. Heavy reduction for 1 hour at cone 012, the medium reduction the rest of the way up. Just shut the kiln down and closed it up tight.
  3. I am new to making and firing my own glazes although I am quite pleased with the results of my second ever firing in my propane updraft kiln. Granted these were the only 2 pieces that turned out this well. It was just the Malcolm Davis shino recipe. You will have to forgive the cell phone camera photos at the office...
  4. I am wanting to try a kaki glaze in hopes of trending more towards red/spotted rather than brown, however up to this point I have been utilizing my too-big updraft gas kiln for cone 10 reduction atmospheres. I know I could do a full load of kaki in an oxidation atmosphere, but with my limited hobbyist production volumes, risking that quantity of failure makes me nervous. I read somewhere that you could fire kaki in a reduction atmosphere, yielding brown, then re-fire in oxidation along with the next bisque load to have a more red outcome. Anyone ever tried this? Thanks! Brian
  5. Not to stir up to much jelsouly, but I work for a not-for-profit healthcare organization and get to buy my personal propane at the hospital rate... $1.35 /gal. Maks the 200 gal fill not to painful. The tanks lasts for 5-7 firings in my 27cf kiln. Cheers!
  6. Freezing!

    Now that it has gotten down to -10 here in MT, I have discovered my shop does get below freezing... Frozen fresh greenware has some interesting patterning! I also love re-wedging boat loads of clay... I have resorted to schlepping my clay and greenware to/form the shop as it would be impossible to keep the wood stove going all the time. I have set up a table to let the greenware dry in the house, but I am making a mess and running out of space in a hurry. Any concerns about storing it in the shop once it is bone dry? Many thanks! Brian
  7. Close to getting a pad poured for my 27 cf updratf propane kiln and I am starting to think about a cover structure. It will be next to a metal sided shop with an extension built off of that, so it will be in a corner if you can envision that. I was thinking a slanted metal roofed off of the main building. 1. Other thoughts? 2. If i were to build a chimney, would it help prevent stall out near cone ten in heavy reduction? What type of roof clearance from the top of the kiln would be required with a chimney? 3. If the chimney is a no go and the top of the kiln is 6 ft, any clearance suggestions? Roof Slanted away from building or doesn't matter? I appreciate input from the collective wisdom! Pictures of your chimneys or cover structures are helpful, Thanks! Brian
  8. Gas kiln

    Moving day was a success! An ordeal as anticipated though. With the internal skeleton I built everything stayed in place during the move. Although a forklift would have been nice, we ended up using tractors as that was what we had on-hand and the kiln already had big bolts welded on each corner for that express purpose. I put it in the shop for some minor hardware and brick repairs while I work on getting the slab pored. The guy I bought it from said he would, at times have difficulty with the kiln shutting down on it's own. As a result of this I am going to replace the thermocouple and pilot light. QUESTION: I know there are different types of thermocouples out there, but none of the thermocouples at the local hardware store differentiate between the types... Any suggestions on what has worked for you in the past? More to come as it develops. My better half with the kiln.
  9. Gas kiln

    1500 for the kiln, furniture, 500 gal tank (20%) full and the move. Thanks for the tips! Moving day is on Friday! I will start constructing the braces now and be sure to take lots of photos along the way.
  10. Gas kiln

    Hello, New to the group with a question. I have used gas kins in the past, at a college studio, have since moved out to the sticks and don't have much in the way of local resources to fire my work. I have a line on a 36cf gas updraft kiln, comes with the 500gal propane tank and transport for a small fee. Screamin deal overall. The kiln was fired less than a year ago and was in working order at that time. There is no reason to assume that anything major has changed during that time. Everything appears to be in order to my untrained eye, but I wanted to get your opinions on things to look for and consider prior to jumping in head first. I would add that the kiln has been outside for 15 years and looks a little rusty accordingly, but all the structural steel appears to be solid, unknown if it was new or used at that point. I could also put it in my shop, but would then have to vent it. I thought having the ability to bisque and high fire with one kiln would be efficient. There is a small bunch of us in the town who would love to have local access to a gas kiln, and chip in on the gas bill i'm sure. I have a concrete pad I could put it on, although it is outside. Thanks for your thoughts. Brian
