  1. So another question on plaster of Paris, can I also use it to make bowl or plate molds safely to put slab clay on/in???
  2. Thank you! I have heard about both pottery plaster and plaster of Paris hoping plaster of Paris would be great to use because it's easier to purchase and cheaper!!!! Stay safe everyone!!
  3. I'm wanting to make a few damp boxes. My question is can I use plaster of Paris???
  4. Neil, You're saying to try closing the bottom peep and leave the top peep open? I don't have a vent as of yet, the kiln is in a room w window off our garage.
  5. Should the 2 peep holes be open or closed? The hood of the kiln also has a small vent hole.
  6. Thanks! So should I fire glazed pots or Just a bisque?
  7. I just turned on the kiln for a few minutes, cracked the lid and all elements were red. The max temp is 2300. Also there's an automatic dial which I used for my test fires, or manual low and manual high.
  8. I will check the elements for sure!! When you say a cone 6 kiln doesn't fire to cone 6....because this is so new to me....will I be firing to cone 5? And using cone 6 clay?
  9. It's a Duncan kiln The teacher model DA 820-2
  10. The cones were on the bottom shelf about 1" off the bottom base of the kiln So when the kiln is full of pieces to fire, what happens to the ones on the bottom shelf, compared to those in the middle and top??
  11. I have a small electric kiln that I've test fired. I'm very new firing kilns.... Cone 6 in the ASD Cones 5,6 and 7 for witness cones. One set on the bottom shelf in front of the peephole and the other set on the top shelf in front of the peephole. Safety timer switch turned to 20 Switch set for high fire Kiln turned on, the ASD cone 6 tripped it off, the safety timer switch had 1 hour left on the dial Kiln turned off and cooled After opening the kiln (it was an empty kiln because I was test firing) the top set of witness cones were fine, cone 5 overtired,
  12. Hi Andrea

    I'm test firing a kiln and I need your opinion.   Cone 6 in the ASD, cones 5,6 and 7 witness cones. One set on bottom shelf by peephole and one set top shelf by peephole.  Kiln set for high fire.  The safety timer knob set for 20 hours.  The kiln is empty because I'm test firing and I'm very new at this!!!

    So the kiln finished firing and cooled.  I open to collect the witness cones.  Top shelf cones are what they should look like for cones 5,6 and 7....I'm happy with that.  I remove the next 2 shelves for the next set and the witness cones are white and standing straight up???? Why would this happen??

      Is this a new or used kiln and what was your firing schedule?    Denice

      Hi Nancy,

      Sorry it's taken a while to see your post. I'm afraid I'm really the wrong person to be answering this question. You should put it to the forum. My kiln has a temperature difference between the lowest and the highest shelves and this factor is always the case.  This also happens with the way you load your kiln. Top heavy or bottom, biggest pieces in the middle or at the bottom, etc. Have you fired anything since? It may also help you to take a photo of the load prior to firing so you can see how your loading is affected with regard to the cones. Curious as to why you set your safety timer to 20hrs,  Hope you have fun with your new kiln. Andrea
