      Moderators needed!   12/08/2017

      Ceramic Arts Network is looking for two new forum moderators for the Clay and Glaze Chemistry and Equipment Use and Repair sections of the Ceramic Arts Network Community Forum. We are looking for somebody who is an active participant (i.e. somebody who participates on a daily basis, or near daily) on the forum. Moderators must be willing to monitor the forum on a daily basis to remove spam, make sure members are adhering to the Forum Terms of Use, and make sure posts are in the appropriate categories. In addition to moderating their primary sections, Moderators must work as a team with other moderators to monitor the areas of the forum that do not have dedicated moderators (Educational Approaches and Resources, Aesthetic Approaches and Philosophy, etc.). Moderators must have a solid understanding of the area of the forum they are going to moderate (i.e. the Clay and Glaze Chemistry moderator must be somebody who mixes, tests, and has a decent understanding of materials). Moderators must be diplomatic communicators, be receptive to others’ ideas, and be able to see things from multiple perspectives. This is a volunteer position that comes with an honorary annual ICAN Gold membership. If you are interested, please send an email outlining your experience and qualifications to jharnetty@ceramics.org.

  1. Hi, I'm a newbie! About a month ago, I made a few small objects using terra cotta clay and let them dry all of this time in my studio on the second floor of my house. I live in Maryland and the weather has been varying between 30 degrees and 50 degrees outside. We keep the house at 68 F. So, today, I decided to do a bisque firing of this greenware and also, fired some smaller objects made from white clay that have been drying for about three months (I had forgotten about them.) My kiln is a Paragon Quickfire Kiln, which I have used for bisque firing before about five times, the last two firings including this one wasn't successful. Today, when I fired these objects, two of the terra cotta objects exploded to pieces and so did one of the while clay objects. Again, these pieces ranged in size, but very small. I fired according to the kiln directions: fire to 500 degrees with a stilt propping open the hood, then removed the stilt to fire to 1950 degrees, cool to 1500 degrees and fire to 1950 degrees. At about 700 degrees, the first explosion happened, which was a small barely audible pop sound. At about 800 degrees the same sound again, so I turned it off and unplugged it. As it was cooling, there was a louder explosion, which caused "smoke" or clay powder to exhaust from the top of the kiln hood. Then, luckily nothing else happened. One piece was completely shattered, made of terra cotta and the thickest of the pieces. Another had pieces that had exploded off of it. The last, a piece that was an inch long and a quarter of an inch think sheared in half length wise and broke apart. All of the pieces seemed dry. Not sure what happened. Seems to me that it is most likely a combination of the drying not being complete and the kiln. (I'm going to be purchasing an electric digital kiln soon, which I hope will help with part of the problem.) So, is there a good way to dry clay? How long should it dry for? I've heard that putting clay in a regular oven can help with drying...is that true? Thanks for the help!
  2. Kinda petty. Fine request, but I wouldn't want to be ignored. I'm ignoring you. Jim As memtal health therapist in my day job, I think that's fine John. I'm analyzing you. Uh, just kidding. Sara Cahanin

  4. I'm fairly new to pottery and live in the Silver Spring area. While I take classes at The Little Pottery Shop in Frederick and have my own studio space at home, I would find the experience you are thinking of offering invaluable. I'm not sure where you could list...other pottery course places? Plaza Art? Any way, I would be mtersted very much.
  5. I have a Speedball Artista wheel tha it bought a few months ago. It was set for left handed use, but I called the company and they told me how to open the unit and switch the wires for right handed use. Since then, the wheel head seems slightly off (tilting a bit) which is very pronounced when a plastic bat is on it. Plastic bars came with it. The wheel makes a whooshing sound. It has a warranty and I can send it for repair, but I wanted to see if there was a solution suggestion. When I go to pottery class, I can through a pot well, but at home, it doesn't go so well. My spouse thinks its the wheel. What do you think? Thanks!

    I don't mean this to sound callous or judgemental, I'm just curious, did you really do this? Having just lost a dog a bit ago, I can imagine this must have been difficult. Thanks for your response.
  7. I have a few stains that I've used to color slip, but whats the bet way to color a purchased white clay body? I've heard that using a mixer is good, but wouldn't that mess up the mixer?
  8. Please give me some pointers...I've never done it. I do have a wedging board with and without canvas on one side. I've been told a wedging board helps. Thanks again!
  9. Once again: how do I reclaim clay?

    Well, this is clay from the pottery wheel (trimmings) and from hand building. It's all in a bucket with water. Do I drain off the water, put it on the plaster or a few days then wedge? Being sans pugmill or mixer....that's what I usually do. If you let the bucket rest long enough for all the clay to settle to the bottom, you can pour off the clear water from the top (put it into another bucket for future reclaim use), and then lay the slurry out onto the wedging board. Wedge it up when it's dry enough to work. Depending on the temperature/humidity/thickness of the slurry on the board, this could take a few hours to a day. Maybe two, but check it often after the first 24 hours. Some people say that you can put the slurry in a pillowcase or pant leg that's been stitched up on one end, and hang it from a clothesline. I've never tried that, personally, though I see how it could work. Thanks for this info. Very helpful! I joist didn't want to do this without being absolutely sure the method!
  10. Once again: how do I reclaim clay?

    Thanks Denice. When you said, "turn the clay over and put the top side against the plaster half way through", do you mean that you have it on the plaster and then flip it over? I was a little confused. Thanks!

  12. Where in Upstate NY?
  13. Hi, seems as if GlazeMixer is not out of business. I saw a charge on my bank account and then checked my account with them. The glaze has been mixed a shipped. They never did respond to my two emails or one hone message. I'm it sure what to think. I'm not really impressed with them customer service wise.

  14. Recently, I heard about Glaze Mixer (www.glazemixer.com) as a forum to share glaze recipes and to order glazes to be mixed. Last week, I ordered several colors and despite emails and calling the company, I haven't heard back from them. Te phone number doesn't say the company name in the announcement either. While my card hasn't been charged, I'm concerned that this site may not be legitimate or out of business. Any info or suggestions would help. Thanks!
  15. Glaze Mixer seems to,have gone out of business. Thanks!
  16. Do you know of any other glaze mixing companies?

    Thanks! full disclosure, I work for them, but alligator clay in baton rouge (aka southern pottery) will also mix glazes--materials cost + 10 dollar mix fee I believe. (http://www.alligatorclay.com) Is there a specific link for ordering? Thanks!

  18. Re firing

    you do know that cone 05 is hotter than cone 06, right? piece looks good I've read you can refire, if you fire at a lower cone. In this case, cone 07.
  19. Thanks Patti! I'll wait a while longer. Glad it's been a good experience for you!
  20. Well, I don't have a joke, I must say that pottery-speak is quite funny in itself. My studio instructor keeps telling us, "Don't forget to clean your bottoms!".
  21. Cascade glaze did not drip

    Did you fire at 04 first, cool then fire at 06? That's what Mayco usually calls for. Maybe that's what is needed.
  22. Hi, I'm just curious, How long does it take plaster to dry that was poured for a wedging table? We poured it today....50 lbs of potters plaster as required in the wedging table's directions.
