  2. neither of these posts for that school show a location. a state or town name would be helpful. if you think the www stuff works, it doesn't.
  3. What do you use to mix your glaze

    callie, i have always wondered why some people use a brush with a sieve. i use a blue kemper rubber kidney and find it works very fast and makes cleaning out the last drop easier because of it's shape. when i got a sieve with a brush a few years ago, i found washing out the brushes wasted a lot of time and glaze and it was very slow turning the attached crank. sold that thing to someone who was happy to get it. what advantage do you have with a brush? inquiring minds want to know. and so do i.
  4. making a combination of things. big pieces with leaves and birds and small, about 3 inches across lace impressed bowl shaped "containers". the small items will sell if i can get a nice glaze in several colors. the bigger ones also sell, depending on the venue. but the small stuff is my version of mark's sponge holder bread and butter item. not that they hold sponges, just that they sell quickly and bring in cash. got to make some glazes!
  5. Cracks in greenware

    as old lady says,don't waste time trying to fix, cut in half, you,d have to be pretty slick on wheel and trimming to get even thickness with this shape. drying rack solid or mesh so air can circulate freely? the pot rising from saucer would Imo result in a thin saucer rising into a thicker base/saucer meeting place. also on firing, there will be an uneven heating goin on because of this. I 'd be tempted to fire on rim or on coils.
  6. neat pattern! promise i won't copy it. i do use seashells and make sort of oceanish things, the pattern is very like a nautilus.
  7. Cracks in greenware

    this pot will not fix. if you want to learn more, try trimming it by cutting off the saucer part. or, cut the entire thing in half vertically to see your thickness as it is today. you might learn more for the next one of hundreds of this kind of pot. call it practice.

  9. Cracks in greenware

    It was on its base when drying. I had used the wire to cut it from the bat and then left it on the drying rack. The wall thicknesses are pretty consistent. Do you think it’s salvageable? Is there a way to fix the crack?
  10. Cracks in greenware

    too fast drying of uneven thicknesses is my bet. was it on its rim or foot when drying? really slow drying, don't know your humidity, is best for uneven thicknesses, get it on its rim asap cover with plastic if necessary. cold only a prob if means moisture retained or pot frozen....
  11. I have posted PKQotW #42 and added the Answer key to #41.

    Sorry to be so far behind. . .

  12. Newbie without bentonite

    Thanks for the info! I guess I learned not to trust the clerks at the local pottery store
  13. Damaged kiln cord

    Try minimizing the Paint window, and bring up the image file in its file menu. Drag the file into the Paint workspace and see if that works. best, Pres
  14. I make planters with built-in saucers. The other day, this one cracked before going into bisque. Is it possible it got too cold outside? I keep my pieces outdoors in Florida under a covered patio on a screened-in porch but it did get pretty cold last week overnight. Would temperature cause these cracks?
  15. Week 42 The preferable method of casting a catenary arch kiln is to use the casing material on the: Outside of the form upside down. on the outside of the form right side up. on the inside of the form right side up. on the inside of the form upside down. The project casting in the book used a mix that was: hand mixed sand, vermiculite, clay and concrete hand mixed commercial Vari-Form B commercial Carborundum's LDS Moldable hand mixed sawdust, pea grog, clay, and cement Three things can be done to improve the strength and working properties of the casting mix: application of a heavy coating of ceramic-fiber liquid cement upon the interior surface of the cured casting; embedding lath wire one inch into the center of the tamping mix during application onto the arch form; and the use of_________________ instead of water. 50/50 water and dish detergent 50/50 sodium silicate and water colloidal-silica liquid mortar set liquid The ______________ brick is the load-bearing brick which takes the thrust from the completed arch. Keystone channel arch skew This weeks Pottery Quiz of the Week questions come from: Kiln Building with Spage-Age Materials, Frank A. Colson, c. 1975, Van Norstrand Reinhold Company, New York,NY Note from Pres: Always interested in kilns and firing, this book seemed appropriate for the Space Age, and from an energy-efficient standpoint. After all, we were having problems with petroleum fuels at the time, and many were changing over to electric, or insulating their kilns more for greater efficiency.

    "right click on photo, select "open with" left click and select "Paint". go to home, choose resize, then choose pixels and enter 600 for the horizontal size. the vertical size will automatically become 450. then save it. once saved, post it here. thank you again, john." Thanks dlpotter and oldlady, and I tried to do that, but photos on my laptop has been sort of disabled - long story about lack of storage - and when I right click I don't see Open With, and nothing else there takes me to Paint, nor can I find it anywhere else. (which doesn't mean it's not in there..... somewhere). I haven't had the time or inclination to spend another afternoon on the phone with tech support, tho I have to again soon. But thanks for trying to help me. Hopefully I'll hear from L&L tomorrow and find out what I need to do to get it up and running again. another old lady

    The recipe contains 8% kaolin and 17% gerstley, so it should stay suspended reasonably well without the bentonite. There are various types of bentonite. Some used in cosmetics and soap might not be appropriate for ceramic glaze . I would be careful without knowing exactly what type of bentonite was used in the facial mask. Whiting is sometimes used in the paint industry as a white pigment, but in a ceramic glaze it melts into calcium oxide, a flux, and would change the glaze. If you are seeking to opacify it, use one of the materials suggested by Min.
  18. you beat me, Pres. I stayed over at a friend's in Billings. Doing laundry today. Had a great time hanging out with you and the others. Also caught Spring's very personal talk on her own educational experiences from travelingl. It was great to meet her in person.

      Both of your friends were fun also, I hope the one is well on her way to recovery. Great seeing you once again. I can post pictures later on this week.

    Whiting is calcium carbonate which acts as a flux. To opacify, zircopax, tin or sometimes titanium dioxide is used. edit: Pres linked a glossary to the top of the Studio Operations and Making Work section, it's a good place to look up materials etc.
  21. Thank you for all the insights! It's strange to me that only some of the pots were burnt on the bottom as most of the pots had the wax totally melted off. I'll certainly check the vent, although there was a glaze firing with wax resist in between the two firings that produced the strong smell/burned bottoms. That middle firing produced no burning and no smell. There are two jars of wax resist floating around the classroom so maybe I'll test each to see if one jar is contaminated and the other isn't. Or maybe I'll just stop using it... Thank you again!

    This recipe doesn’t have whiting as an ingredient. I planned on adding whiting on top of the 100% ingredients of Kitten’s Clear as well as some mason stain. I am hoping it works as an opacifier.
  23. Thanks for posting my question Pres. hanging planters for succulents
  24. Back from NCECA yesterday. All unpacked, and doing laundry. Exhausting week, but well worth the time and effort. Lots of demos, lectures and other to visit.

  25. Newbie without bentonite

    just a question about adding whiting. do you mean that you are going to add to the final recipe which probably equals 100 the chemical called whiting which is calcium? or do you mean that you intend to make the glaze white by adding some opacifier like tin oxide or zircopax? i ask because the ingredient whiting is usually included in the base recipe to reach the 100 percent so it is already in the glaze mix.
  26. Msk

    colleen, can you tell what effect you hope to achieve by adding sand to your underglazes? and, does "paint" mean "glaze"? i ask because there might be a different way of getting what you want on the final piece.
  27. Thank you - here is the finished Baby Hippo. (Sorry cannot get the photo to reduce jpeg on my ipad ) Clear matt glaze shiny parts, but as its a sculpture it just adds to the interest. Worked just fine. Phew
