  1. how hot?

    This is the first I've ever used cones, so I was unaware that there were different colors for different levels. Live and learn. Bob
  2. how hot?

    Mystery solved! As you can see in the image below, the bag is labeled for cone 5.5 cones, while the actual cones in the bag are 05.5 That's kind of a big difference. I wasn't wearing my reading glasses and just looked at the package when I got the cones out instead of looking at the cones themselves. So, somebody doing the packaging messed up. I wonder how many other bags of these got packaged incorrectly? I suppose I should wear my glasses more. I discovered what happened because I was wearing my glasses today while putting things in the kiln. Ah, the joys of getting older. Now to get some new cones. Unfortunately, I can't just run to the nearest ceramics supply store and pick some up, since there are no supply stores within a day's drive of me. I'll have to order them. Oh, well, at least now I know. Bob
  3. That was my first thought. I'm trying to keep a closer eye on him and keep him moving along and not overworking the clay.
  4. firebrick crack

    Thanks for the advice. I'll see if I can find some kiln coating for starters. Bob
  5. firebrick crack

    For some reason the system wouldn't allow me to upload more than one photo into a single post, even though they were each under 500kb. So here's another, closer look at the cracks.
  6. firebrick crack

    Does this crack in the firebrick in the lid of my kiln need some kind of attention? I've been told both yes and no. It's a Shimpo DUA-15 kiln. Bob
  7. No, they aren't finishing in one period, but he had problems the very first period with the clay. We're just using some basic earthenware clay, nothing fancy. As far as storage, I put the projects all together in a sealed plastic storage box with a good number of sponges to keep things from drying out. It seemed to work for that, it's just when he's working on things that they get really cracked. Thanks. Bob
  8. I tried the latex gloves with him today. I think it might have been a bit better, but I need kid-size gloves, since they were hard for him to work in.
  9. Yes, he is working in the same spot, kind of against one wall. I believe he might be under a vent or something, too. I'll have to look at that tomorrow. There is another kid sitting right next to him, though, and his clay seems to be fine. Still, I'll have to pay attention to that. Thanks. Bob
  10. Thanks, those were good tips.
  11. I will try that, or have him work on a different surface. I'm not a fan of canvas, either, but it's quick and fits on the tables easily.
  12. I have a 4th & 5th grade after school clay club once each week at school, with eight students. We've had three classes so far and the kids are working on pinch pot critters. I have one student who seems to dry his clay out very quickly, to the point that it gets irreparable. After his first pot fell apart I had him start over during the next class. That pot is also not doing well, but is holding up better than the first one. This kid wears shorts all year round, even when it's only about 25 F outside. He doesn't seem to get cold. Could his body temp be just enough above normal that his hands suck more moisture out of the clay than normal? It's the only thing I can think of, because he's not using a really absorbent surface to work on, just a canvas mat like everyone else. Any thoughts or suggestions? He kind of goes overboard on the water if I don't keep a sharp eye on him. Thanks
  13. Me - Teach a Class??!

    What they all said. I was scheduled to teach high school ceramics before I had learned it myself. Our other art teacher was leaving so I was tagged to be "it" for the next school year. I had about one week of lessons during the summer, then learned from YouTube and a pottery wheel in my classroom nearly every day, and a local art college ceramics student once a week for the first semester of the school year, then started teaching it second semester. Yikes. I discovered I loved ceramics. I also learned very quickly as I was teaching my students, I guess because I had to stay one step ahead of them. But I've always been very upfront with my students about what I do and don't know about ceramics. Sometimes we try to solve problems together. It's fun, and it's been my favorite class since the first semester I taught it. So again, I think there's a lot of good advice that's already been given. Enjoy your class
  14. how hot?

    Thanks. I'll assume that's what happened, then. The glazes seemed to turn out fine.
  15. how hot?

    I'm fairly certain it was a 5.5, but there is a chance that it could have been an 05. Would that be enough of a difference to melt it?
