  1. Is there a material, or a glaze property, that predicts if a glaze will generate one color at one thickness, and another at a different thickness, specifically when pooling? Joel.
  2. I got time to watch that video Bill and it was wonderful!!! Thank's again!
  3. Thanks Bill. I don't think it was you, but that looks like some awesome material to go through. Thanks again! Joel.
  4. Someone posted some insightful work on glaze chemistry with a couple of great graphs. The covered the silica-alumina ratios and where different effects would occur on a triangular graph. I can't remember much more than that, so this is a Hail Mary. Would anyone know the person's name, or about when those posts were made? I've must spent a half-hour searching with no luck. Joel.
  5. Just a tad under 12 on one try, three pulls, with a bottom. Joel.

    September '13

    Some work I did in September.
  8. I think Bailey is a good company. However, I've used their wheels and their pugmills and from those experiences I've concluded that the engineering behind their products is geared towards a narrower definition of the device than is appropriate for what I do. It is like they got ten pottery magazines and averaged the most common complaints/expectations of the device and then engineered from there. Theirs tools don't seem to be so much build around the job being done as they are built around commonly held expectations. Joel.
  9. I tend to have different needs than most potters it seems, so you can take what I say with a grain of salt, but... I like the Brent because the pedal is a little lower and for production work, to me, a pedal that is closer to the floor means less fatigue. The Baily's pedal is pretty thick. I don't like the splash pan since it makes it difficult to make some of the production items I make. I prefer a removable splash pan since I prefer more versatility in a wheel. Though not my first choice, to me the Brent is a professional machine, a rare item in the pottery world. I will say that the Bailey
  10. If you don't have a reversing switch I think you can make one with a bridge rectifier. Joel.
  11. Thanks John, that was very helpful. Joel.
  12. I would really like to know what Barium toxicity is as it applies to pottery studios. I'm told you would have to eat a tablespoon for it to kill you and that it doesn't build up in your body like some heavy metals do. In my studio I give cobalt the same respect I give barium. Joel.
  13. You can look at the bisqued pot as a vessel that can hold a volume of water. The lower the temperature of the firing the more water it can hold. You can look at the glaze slurry as a vessel too. In this case, the percentage amount of clay (and/or bentonite and some other chemicals) combined with flocculation/deflocculation, control the amount of water per unit of glaze. This is kind of represented by specific gravity (volume of slurry divided by the weight of an equal volume of water). We have to have both volumes in balance if we want to have consistant control over the look of our glazes

    Teapots drying

    From what I can see of your handles, it looks like you have good control. Joel.
  15. Nice bowls. I love it when people take the motion of the wheel and incorporate it into the work. Joel.
