  1. I'm going to add a third leg to Hulk's continuum. You could be anywhere between the 3 legs. A studio potter in my estimation, is closer to a artist in that they may not be concerned with volume the way a production factory is. It's harder to use the "hobby" label on serious studio featuring all the necessary tools and a 20+ year investment in time. There are lots of reasons why the income from the process may not be required for necessities, not related at all to lack of skill or dedication. In My Opinion (since I'm not one), a production potter is in fact limited in the amount o
  2. I think that is THE RIO available now. The Spanish RIO is generally not available anymore I believe. The stuff they are calling natural is what I was getting as brown iron oxide.
  3. I hate to even ask, as my materials storage is really full. I did think I had every available raw glaze ingredient, now you ask for synthetic red iron oxide. O Well. It's not even on Baileys or Laguna catalog. Where to get? I assume it's more "powerful" than red or even black iron oxide. Is that the difference? Is there a substitution ratio? What difference would I see if I ran tests between RIO and synthetic? For that matter Bone Ash and the synthetic? Just More Better?
  4. Challenge accepted. Both have inherent complications, gas firing simply has more. No where is gas easier or simpler. Obviously, first off, the management of atmosphere. Balancing damper and gas pressure. Knowing the kiln well enough to work with uneven reduction. Putting aside the modified electric to gas conversions, a typical gas kiln costs substantially more than a typical electric kiln. I would describe the typical gas kiln as about 24 cubic ft and the typical electric as 7-10, so a typical gas kiln has a larger footprint. An electric kiln is more likely to have an au
  5. Not surprising to me your explanation is mostly centered around academic ceramics. That's where most ceramics happens. Also, Cone 6 electric is just easier in every way than cone 10 reduction. Some of those ways are a very big deal.
  6. I'd like to see the glaze. Would this be considered a good food safe glaze? Not many of us firing cone 10 anymore I think.
  7. I'm convinced the best cookies for this are cut soft brick. I use a bandsaw with a shop vac attachment, because as previously noted I'm a tool geek. Cut on a bandsaw, they're perfectly even and absorb glaze really well. They're easy to grind off if needed. Without the joy of tools, a hacksaw and some patience will net a box full. They can be reused indefinitely. At least until they perform the glaze soak function. Most any old softbrick will cut into nice cookies. Don't need to use new ones, just have hoarder friends with piles they'll never use.
  8. In Southern California we would do something like this in the desert. I'd suggest some kind of similar environment. Maybe on a beach? Nottingham Art in SC did a pit firing in a open industrial area with FD permissions. If you could delay and schedule for a rainy day, maybe that would be an advantage.
  9. A diamond disk on a plexi bat on the potters wheel head with a water drip is well worth the trouble to set up. The diamond head when kept wet lasts a really long time. I put a drain to bucket in the catch pan. Live by the runny glaze.
  10. Follow up on the original post. Rented a very large wet tile saw. Thing had a 20 inch throw. It was loaded on my truck with a fork lift and I ran it in the bed of the truck. Went through the SC shelves like butter (almost). New damper works fine on 2 firings so far. Problem solved and 1 warped shelf eliminated from the rotation.
  11. What temperature would a cone 10 firing shutoff system be set at? Inattention kills, that's for sure. I see it everyday on the So Cal Freeways. Maybe self driving cars will eventually be better. Hard to say. Now that I think about it, what emergency control do non computer control electric kilns have? Lots more of those around than gas kiln these days.
  12. I'm curious as to exactly what scenario or event a high limit shutoff system could backup where an experienced operator in attendance could not. I'm looking to know the emergency that would cause the backup to trigger. Like the operator has a heart attack, while waiting for cones to drop. I ran into similar consultations when I was a telecom tech. The client would ask about backup systems and I would always ask what emergency are you protecting against? A power failure is much different than a hard drive failure. You can't protect against every possibility, so consider what you th
  13. The belts come directly from Laguna. Replace all 4 and keep any that have no cracks when you bend them as spares. The wheel will run perfectly fine with 3 belts, but is noticeably under powered when centering more than about 15 lbs of clay. There really is no good upgrade for the belts such as changing both pulleys and using a V belt. In order to get torque from a small motor, the drive pulley is as small as possible and the driven pulley as large as practical. The drive pulley on the Pacifica is only about 3/4". I couldn't find a V belt pulley anywhere close to that. I always g
  14. Cone 10 stoneware here. I don't glaze the inside of planters either. I know potters that also specialize in planters for xerophytes (cactus and succulents primarily) who do glaze the inside. For most house plants, I still wouldn't glaze the interior. It's actually a complicated subject. A lot of ins, outs and what have yous. The soil mix is going to have more to do with the water retention that the inside surface of the pot. To me the number one reason is I can stack another pot inside for the glaze fire. Very economical. Also no wasted glaze.
