  1. Nothing wrong with mold. It is organic and may add plasticity to your clay. And will completely burn out as you fire. Keep potting! Stuart
  2. I get credit cards in the mail (unsolicited). I cut them into varrious shapes and use them as ribs.
  3. If it goes around, it's a wheel. Clayton Bailey made a wheel in the early 1960's from a Singer sewing machine that you straddled and pumped the treadle up and down; left and right. What a headache! I bought the third wheel that Robert Brent ever made in his Los Angeles studio in 1966. Used it for fifteen years, then sold it for what I paid for it. It was a wooden box with pulleys and belts. It had a forward and back foot lever attched. The box hummed at slow speeds. MUMMMMMMMMMM If the price is do-able buy it. Ask yourself: "Can I make X dollars worth of pots on it, then it's worth a % of X dollars. Cici Finley, a potter in Patagonia Arizona says: If someone offered you a battleship for a dollar, would you buy it? The bigger question is: Where will you park it and can you afford the parking fee? Cici worked for many years on a treadle wheel that she bought from Bernard Leach while on sabbaticle in England in the 1950's. Stuart Keep potting!
  4. Sounds like a great idea. If you use oxides or carbonates; cobalt, iron, copper etc., you might want to grind them to a finer mesh so they'll mix more evenly with you wax. A ball mill or mortar and pestil should do well. If you apply them over a glaze you may find that they may be food safe. Let us know of your results. Stuart Keep Potting
  5. Well said. Been there, done that! Now comes the hardest part: COOLING the Kiln. Enjoy your holidays. Stuart Keep potting
  6. Try painting the visable edge of your cones with a thin coat of black cobalt oxide for visability (cobalt will not flux the cones) . Also set the witness cones so they fall in the opposite direction from the temperature cones. Good luck, and keep potting, Stuart

  8. Hello azjoe, I'm potterstu in Tucson AZ. Where are you? Do we know each other? Look me up.


  9. Here's a C/6 oxidation recipe for a very nice berry like red. Slightly transparent it works best on white bodies. Because of it's translucency, it's fun to do some design work under this glaze with colored slips. Try it: CHROME RED Glaze. Gerstley Borate 21 Nephsy 16 E P Kaolin 11 Ca Co3 Calcium Carbonate 20 Silica 32 Tin Ox. 5 Chrome Oxide 0.15 Keep potting, Stuart
  10. Back in the mid 60's and early '70's we had very little knowlegde of Raku techniques, or safety. I remember gloves made of pure 100% asbestos! As hippies on Venice beach we found a pile of old red brick, fashioned a very crude kiln, attached a garden hose to a gas meter, cut off the end of a burner from a discarded hot water heater and used a couple of childrens crutches as tongs. I still have a few of pieces from that p[ile of brick. At a workshop in Colorado in 1972, we got a box of some material (an early form of Fiber Frax, I think) from Corning. They were testing it for insulation in things such as space suits. The challenge was to use it in any way we wished, then report back to Corning. We used it to patch cracks in kilns, we mixed it in clay and finally using the last few yards, we lined the carboard box it came in then built fire brick platform and proceeded to fire with our carboard kiln! It lasted all day and into the night, until a pair of tongs tore the insulation and we watched our kiln go up in flames. It was GREAT! We now fire with a sophisticated motorized kiln, and the results are just as good. Raku: It's for the pyromaniac in you. Keep potting, Stuart
  11. I too am an older potter (68). As an apprentice in the early 60's, we often received five to ten tons of dry clay in 100 # bags. >>>there was no OSHA! And no training as to how to lift or carry, so we would turn it into a competition to see who carry the most the quickest. As a result I've had L-4 L-5 issues ever since. I have a routine every morning of streches. When I'm at the wheel I do a series of "mime" moves imitating throwing in a mirror. In other words, I imitate the throwing of a pot but from the other side. This helps a lot. I also get up and walk for about five minutes at least once an hour. Wearing a back brace has been suggested and I use one sparingly as I'm told that if you rely on one too much, you risk muscular atrophy. (sp?) Good luck with the move, Stuart
  12. I bisque at C/04 and fire raku at 07 to 06. This helps in two ways. I agree with Marcia that bisquing higher than the final firing helps ensure strength, and I sometmes like to burnish my clay and by firing cooler than bisque, I don't loose the burnish. Stuart
  13. Back in my appreniceship days, early 1960's / I'm old, we never heard of "bend at the knees". There was no OSHA, everything came in 100 pound bags and we young naive appretices would race to unload the five to ten tons of bagged dry clays that arrived every three months. AND yes, we all now suffer with L3, L4 and L5 issues. I get to the wheel at least three sessions a week and take many mini breaks to stetch or just walk. I teach students to do a series of stretches (miming throwing in a mirror) at least every half hour at the wheel. I have two wheels and have one I stand at and the other for sitting. The problem with standing is, you are on one foot and the other is raised on the pedal. Daily stretching is a MUST! . My master's wife danced all her life and taught me some basic stretches many years ago that I have incorporated into my daily routine. Develope a routine and don't skip a day! [hansen has a good list of moves below.] And keep potting!
