  1. These work very well. And for temporary use hollow core doors work great, are lightweight and will usually store upright behind studio doors.
  2. One possibility . .... It could be the breaker that is wearing out. Breakers over time become overly sensitive especially if theyre run close to the tripping point for a long time. An electrician could figure that out for you.
  3. I also spray a commercial underglaze (Coyote Clay) Thinning it down helps with spraying but I try to do at least 3 coats. Being thinned it is absorbed into the bisque quickly allowing the next coat almost immediately. Im just saying Ive never had any problem with gum in a glaze granted I dont and have never used a commercial glaze as I mix my own.
  4. Well thats a good question.. probably 1 to 3%. I mix the cmc in a gallon jug with water and let it set a few days. Then add a quart or two to about 4 gallons of glaze when mixing. In this amount it gives even the most powdery glaze a nice hard coat when dry.
  5. I use cmc gum in all my glaze formulas and I dip and spray. When spraying I add water so it goes thru the sprayer easier. I didnt know there was a problem with gum and spraying and dipping for that matter. My philosophy is this... its all just one big experiment and thats how we learn.
  6. In reduction the oxygen in the iron oxide is removed leaving the pure form of iron FE. Ive done heavy reduction on pieces sprayed with straight iron oxide and come up with a silver gray finish.
  7. That is a perfectly good used wheelhead. You could clean it up a bit with some steel wool.
  8. Good job! Firing a wood kiln is a very grand dance. Porcelain is quite delicate and wont hold up to that heavy level of flame impingement like a good grogged stoneware. It seems they were overfired by a few cones! You might try to use stoneware pieces to act as a bagwall. The rebar will sag. Even more so if the coals build up and block the inrush of cool air from underneath . I see you didnt weld them to the tbar so you could just turn them over each firing and get several more out of them. I pull mine and lay them on a concrete slab and beat them straight with a sledge hammer. Keep up the good work and let us know about your next firing.
  9. I use rubbermaid trash cans. I first pug my clay and then put a layer of clay then plastic then another layer of clay so forth and so on. Then several layers of plastic film on the top and then the lid. Occasionally I will pour a cup or two of water inside to prevent too rapid of evaporation as we have quite a dry environment here. The trash cans are put on mover dollies for ease of storage.
  10. What Neil said. Do you have sinks or toilets or tubs or showers that havent been used in a while?
  11. This. One thing Ive found with fuel burning kilns not reaching temp is not enough oxygen. It seems like youve found the correct amount of gas by adjusting pressure up and down. .. but at 5000ft plus above sea level we have way less oxygen per cubic ft than at sea level.
  12. Can you get Lucas oil products over there?
  13. Look for it on the bottom of the motor.
  14. Drying it sandwiched between two pieces of drywall sheetrock wallboard whatever you call it in your area works fairly well. Make sure its pretty dry before unsandwiching it because if its only partially dry it may still warp. When firing lay it flat on a shelf with fine silica sand under your slab. ...works fairly well but some of the other fine folks here might have other ideas they can send your way.
