  1. Well, there' s not, or it's not placed where the typical reader would find it. If it had been, then I would not have been confused. Seriously, it's a bad teaching strategy to attempt to cast the learner as incompetent for asking a question.
  2. The smallest container of AMACO glaze is a pint (16 oz), but still, yes, not much can be dipped in that. Could be poured, though. Or, it could have been concentrated, like cans of soup, requiring dilution.
  3. I read another thread here on brushing and sounds like it should be applied similar to how you apply shellac; the brush serves to lay the glaze on, letting it do most of the leveling itself.
  4. Min, this is a great post for someone trying to make sense of the glazing landscape. I wish I'd had it last week. I'm not sure that I want the flutes...my guess is that I'd have to make a heavier cup with thicker walls to accommodate them and I think I'm shooting more for a lighter, coffee mug sort of thing. I'll have to play around with a number of options. Thank you!
  5. I noted that those tend to cost a few hundred $$. This subject isn't well-handled by the AMACO website. While I'm sure it's obvious to those of you with experience, it never occurred to me that the pre-mixed glazes were primarily designed for brushing, or that they might be formulated slightly different from the dipping glazes. Likewise, it never occurred to me that the example pieces they displayed were brushed, rather than dipped or poured, or that multiple coats suggested brushed glazes. Part of my blindness is due to our using dipping exclusively in my pottery class, which made me think of it as the primary means of glazing pottery, with brushing relegated to special situations.
  6. Argh, I see that you meant that the flutes are where the Ironstone ran into, not the unglazed part. That makes so much more sense. I couldn't figure out how the Ironstone managed to run down between the flutes with flowing into them. Thanks for your insight.
  7. Great thought....but they still don't provide enough detail for a newbie. For instance, when they say three coats, are they brushing, dipping, or pouring? For dipping, my instructor said for a thicker coat, keep the item submerged longer. Why would you ever need more than 1 coat of the same glaze? I've got three books on glazing techniques and, to my mind, they gloss over (ha!) some of the details that newbie really needs to know. My fantasy book would take a single mug and glaze it with 100 different techniques. Could they be brushing to help control where the glaze goes? I saw an AMACO video where Karen, who does the glazing on AMACO advertising pots, brushed everything on. Some stunningly beautiful work!
  8. Could it be "Cone 6 Pots" ? https://cone6pots.ning.com/
  9. Thank you...fluting does make more sense. Do you think AMACO provides directions for achieving this effect? They don't on the website.
  10. The AMACO site has the following image to show how their layered glazes look. I'm not convinced their colors are totally accurate, but I really like the vertical yellow stripes because they make it look like the mug is glowing from the inside. The clay is buff-colored, so I doubt they look that yellow, so I was considering an underglaze. Any thoughts as to the sequence of steps? My guess is a dip into the base coat, top coat poured over, with a wax resist around the rim. I'm not sure about the vertical stripes....scraped off?
  11. Thanks for a clear set of recommendations. I do think they mop, rather than sweep, at least.
  12. I used to work for a company in the dust collection business, so know a little bit about the subject. These are the sort of units we'd sell to restaurants to clear up cigarette smoke, although a bit larger. They merely filter and recirculate environmental air that floats near the ceiling. What we sold to manufacturing operations was different...there'd be a pickup right where the dust was being generated with a pretty high intake velocity...there are charts that specify the sort of fan needed to make that happen, based on type of dust, number of stations, duct length and diameter, etc. A pickup really needs to be within a few feet of the dust source to be effective. The kilns are in a separate room...I haven't taken a close look at them, but the owner seemed very aware of the venting requirements for kilns, so I'm assuming he's done what was necessary. Overall, the facility is pretty nice and well-organized...it's certainly a lot neater, cleaner, and well-organized than many of the workshops I've seen on YouTube. Thanks for your comments.
  13. The place lets independent potters use the equipment for a monthly fee, so the only people I've noticed mixing are these potters, not the employees. We haven't covered glazes yet in class, so it will be interesting to see what procedures they have us follow. I'm planning on doing the monthly plan, but I'm hesitant to hang around in the area too long. I've ordered my own wheel, so that probably won't be an issue. Thank you
  14. I'm just finishing up a pottery course and I'm wondering about the safety practices in my classroom. Two concerns: 1) It's a combination coffee house and pottery shop, which I see is pretty common, 2) They do sanding and glaze mixing indoors. I see a common recommendation that these things be done outdoors or in a paint booth. So I'm concerned about dust floating around, particularly in a place where food and beverages are consumed. They do have an air filtration device in the ceiling, but it's small relative to the room size and far enough away from the floor that there probably is no airflow in the direction of the unit. I haven't seen anyone use a dust mask. Are these flagrant safety violations or am I being a Nervous Nellie?
