  1. ok, good to know. I am not washing them before I dip because I have underglaze on them. Maybe I should thin the glaze with water?
  2. I'll re-post a pic of the plates that are firing right now in a day or two. Thanks for all the suggestions. If these don't turn out I may go back to brushing the clear on. The clear I am dipping in is for dipping not brushing. Is it alright to brush on dipping glaze or will it fire badly?
  3. I am firing the bisque at ^04 and the glaze at ^05. I have always fired at this temp but usually brush the clear on. I was trying to find a faster way to clear coat so I thought dipping would be a good solution. I did not rub the bubbles out. I thought perhaps the glaze would melt enough and fill them in. There are bubbles on the surface of the glaze after I have mixed it whether it is hand mixed or with an electric mixer. I will spray it with some alcohol and see what happens. I have a two more plates I am going to fire. I mixed the clear and tapped the bucket to settle the bubbles before dipping. But, I still got air bubbles on the plates. I'm still at a loss.
  4. Thanks for the help. I always wash my bisque before glazing. I do all my glazing in one session so I don't think any dust would get on the pieces in that short amount of time, I also use a turn table when glazing to avoid finger prints and when I dip I use tongs. I thought of all those things that is why I am a little stumped. I want to use this glaze with my students so I need to get this figured out. We have a small budget so I don't want to waste this glaze. Any additional thoughts or ideas.
  5. I couldn't get any other pictures to load. There are spots all over the plate that look like the area you see in the photo. Thanks for any help you can offer.
  6. Hello Everyone: I am having some problems with some clear glaze. I purchased a 5 gallon bucket of Amaco low firing clear glaze for dipping. I did my first test fire on two plates. The results were very undesirable. When I dipped the plates and pulled them back out of the glaze there were a lot of bubbles on the surface of the plate. The bubbles did pop on their own and those that didn't I popped myself. I was a little concerned but figured I would fire them anyway and see what happens. Just as I suspected the glaze separated in certain areas around the plate. I did another two plates and got the same results. I am not sure what is happening. I am mixing the glaze with a drill and mixer. I have done this with other glazes and have not had a problem. Do I need to mix the glaze and wait a minute or two before dipping? I am glazing on a low fire bisque so that should not be the problem.
  7. Underglaze

    ok, thank you. I will try thinning out the colors.
  8. Underglaze

    Last semester I had my students create mandalas on plates. Some of them threw them on the wheel and others made them out of slab . We use a low fire earthenware. I have them creating the mandalas using the sgraffito technique so we are carving onto leather hard clay. I am letting the plates dry all the way before I fire to ^04. The problem I am having is the underglaze is chipping off the bisque after the firing. So I am wondering if I am firing to hot, if the students are putting the glaze on to thick or if the underglaze is bad, does one color chip easier than another? I am using ^05 underglaze by AMACO. I went ahead and had these kids put a clear coat on their plates but the clear coat chipped off as well. Does anyone have any suggestions or know of an old thread I can read to help me? I tried to attach a picture but it wouldn't take my file.
  9. My high school students want to start making larger bowls. I myself and more of a handbuilder/sculpture ceramic artist. I was wondering how many pounds of clay per inch when making vases, bowls, plates, etc. I know the type of clay, water, and thickness will all play a part. But, in general what is the correlation? Thanks

    Thanks that was helpful!
  11. I posted this here because I knew more people would respond. I want to go to NCECA this year because its close to home. Ilive in St. Louis, MO. I looked to see if the fees are posted are posted yet and they are not. I am going to try and get my work to pay for this so I have to know around how much it will cost. Is there one flat fee or is each workshop/seminar a separate fee? Do you have to book a reservation if attending? Thanks
  12. I also have large class sizes. My smallest class is 30 students. I only have 7 wheels. It does not help that the class is only a semester so you have to be clever. I do stations through out the semester. Like the previous post, rotating students from wheel throwing to handbuilding. The majority of the class is handbuilding because of the limited resource. It tend to work okay but honsetly students don't get enough time to really get into the wheel becuase as soon as they do its time to switch. To try and fix this if a student is really into it, I let them stay on the wheel. Hope that helps.
  13. Value Of A Kick Wheel?

    I tried to post some pictures but can't get them to load.
  14. I took over a ceramics program at a high school. We currently have a kick wheel that we do not use. though it is cool to show the kids how it works we do not enough time on it to justify it taking up valuable space. Our local ceramic supplier said they would take it in on trade for a new electric kiln and asked me how much I would want for it. I have know idea what the value would be. Can anyone help me and give me a price point to start at. Thanks.
  15. I am getting ready to move into my pinch pot combo lesson with my high school students and thought it would be fun to make Chia pets. I know some other high schools make these but they use stoneware or terra cotta. I have ^05 earthenware. Does any one know if this would work alright to make chia pets out of. Obviously the construction would be fine its the plant part I am wondering about. The ceramic form gets submerged into water over night, I guess to retain the water for the seeds? Then the seeds get smeared onto/into the grooves that were carved during the building process. A hole is at the top of the form so water can be poured in. Any thoughts or suggestions. I don't have the time or money to buy red earthenware or terra cotta so if earthenware doesn't work I will wait until next semester. Thanks
