    Retired (2007) art teacher. Enjoy playing the piano, bird watching, working on the house my husband and I built and travelling occasionally esp. to southern USA and Europe.
  1. Just made a sculpture using coils. It is 17 inches high and 12+ inches wide. It is drying under a drying box made of cardboard covered with plastic. How long should it be left before it is completely dry? One old book suggested putting a dry sculpture in the kiln and heating at 100 degrees F. for 19 hours. Is that a good idea? How fast a rate should the sculpture be fired to maturity? It is a cone 6 sculpture clay with a good amount of grout.
  2. Speckled Glazes

    One of the old commercial glazes I inherited was called Speckled Bone. Maybe the only way to get a speckled glaze is to buy a commercial one?
  3. Looking for a white speckled glaze. What ingredient create the speckling?
  4. Does the surface of the shelves affect the flaking of kiln wash? The shelf where this keeps happening appears to be more smooth and vitrified than the other shelves where flaking does not happen.
  5. Kiln Wash

    There is one shelf where the kiln wash flakes off every time it is newly applied. The other shelves, where the kiln wash is applied the same way, do not have this problem. Any suggestions?
  6. I just made up a half bucket of white slip using the cube in water method. Mixing it up with the paint mixer attachment on a drill was going to be messy. I got a clear plastic bag, put a hole in the bottom to pass the attachment through and drapped the bag over the bucket. After it was well mixed, I pressed the slip through my only sieve, a number 80, and that was a slow process. I filled 6 small jars with the slip: one white, three with various amounts of cobalt carbonate and two with two different amounts of copper carbonate. Tomorrow, I'll throw a cylinder and try these slips. Looking forward to seeing the results. I'm wondering if the process of making the slip might have been easier if I dried out the cubes of clay before adding them to water.
  7. To colour slips, I read that one should add 10 to 15% oxides/colorants to slips, presumably while the ingredients are dry. I am preparing white slip using ^6 white clay cubed and put into water, to apply to ^6 speckled tan clay. What measuring method should I use to add oxides/colorants? I have various stains and the following: red iron oxide, mangenese carbonate, copper carbonate, cobalt carbonate, nickel carbonate and chrome oxide . As I have added washes of these on top of my matt white and speckled bone glazes, it was obvious some were stronger in color than others. This plate was done in the early 80s when I was at college but I can't remember how we prepared the slip! All suggestions are welcome. Thanks
  8. Coloring Clay

    Thanks Marcia. On Richard Gill's work, do you think he applied the underglazes to leatherhard clay and then fully fired it? Does that sound reasonable?
  9. How do I color clay the way Richard Gill colors his plaques? The attachment shows an example of his work. Is the color added on raw, bisque or fully fired clay? What to use - Underglazes commercially made or colorants mixed with a frit? I have 17 different colors of colorants I could use and will be experimenting using them.

      If you don't have easy access to a tile saw, contact a local tile contractor/installer and ask them to cut it for you. A diamond dry-cut blade in a skillsaw will do the job too, but the blade can be pricey for a one shot project.

      Tile zip saw blade should also work.

      22.5 degree angles by the way.

  12. Have small quantities of chemicals I inherited and need glaze recipes for cone 6. These are the chemicals: red iron oxide, rutile frit, manganese carbonate, copper carbonate, cobalt carbonate, nickel carbonate, borax, feldspar custer, zinc oxide, bone ash, chrome oxide, albany slip and barnard blackbird slip. What main ingredients are missing to make glazes? Where can I find recipes to make best use of these chemicals?
  13. Thank you, Marcia. As I am new to this, please clarify "Red art" and "#3134". And in the second recipe are Alberta slip and Albany slips equivalent?
  14. I inherited a small amount of Albany slip and Barnard Blackbird slip in powder form - about 2 cups of each. I am working with stoneware and firing at cone 6 in an electric kiln. As I am new at this, are there easy recipes for these two slips anyone cares to share? These slips are best applied to wet, leatherhard or bisque ware?
  15. Visited Richard Gill's fall show in Burnstown, Ontario, yesterday. He does wonderful wall plaques of places he has visited. He now has wonderful plaques of musiciens. If you don't know his work, google him and you will get a wonderful surprise.

      Ummm. I oversused the word " wonderful" but i like his work so much we have a 2'x1' plaque he made. We also had him made a smaller one from a photo of a lane in Ledbury, England. When my husband looks at it, he is reminded of the feel of the place.
