  1. Armature Help

    I’d place the piece on a “waster” slab. Just a piece of clay that you’re using rolled out to about 1/4 of an inch. That way when the wire melts it won’t run into the kiln shelf and ruin it. You can coat the upper side of the slab with kiln wash. Might help release the piece should the metal try to seal it to the shelf or waster.
  2. Armature Help

    Mikelle- What scale are you working (miniature, life size, larger)? Rough dimensions are good. Having an idea of how large your pieces will be allows options for whether you might need an armature , what techniques to use, what materials might be used to make the armatures (if needed), and what kind of armature might be utilized. Wire armatures work, but you will want to remove them from the clay prior to firing. Padding the armature with paper will help with the shrinking issue as long as the paper is not densely crumpled. You will want the paper to be able to “give” as the clay shrinks. Hollowing the piece is an option, both with and without an armature. This can be done when the clay has stiffened enough to be handled without distorting it too much, but soft enough to allow you to carve away excess clay and to reattach sections you may have cut apart in order to hollow them. As to controlling drying, wrapping with plastic bags, putting the pieces in an airtight container, or under an inverted plastic bucket all work. Hopes this helps you a bit. There are lots of ways to successfully do sculptures with clay. It’s just a matter of finding what will work with what you make and how you go about making them. Regards, Fred

    Andrea- Just roll out some 1/4” slabs of your normal clay body and cut to appropriate size(s). When dry bisque if you want to and coat with kiln wash on one side. Done. Regards

    Very nice, Chris! Sorry I won’t be able to see them in person.
  5. Kneth- are you dipping or brushing your glaze? If dipping, just stroke across it with your fingers or palm just after you pull it out of your glaze bucket ( before the glaze has a chance to firm and dry. If brushing, the only way I can think of, without wiping it off after it drys, is to apply the glaze in uneven layers. Regards, fred

    Marcia- wysiwyg = what you see is what you get.
  7. Mason Stain in base glazes

    RonSa- For color development in glazes, I start with 1-5% for most Ceramic stains (look at the normal use of color oxides in glazes) for stronger, darker stains. For the lighter colors, I usually start with a range of 1-10%. If you were talking about slips or underglazes, then I would consider starting with a range of 5-20% for darker and 5-35% for lighter stains. For clay body color, I’d start even higher. Think transparency to opacity based on the amount of “glass” development in the final product. Just my way of looking at “things clay and glazes.” Regards, Fred
  8. Awwwww, Marcia, now I don’t want a like button either! ;-)
  9. Pres- As you stated, you and Marcia don’t have like buttons. Can’t see if I do or not until I write something, hence my reply to your message. Best, Fred
  10. Slip design over chattering?

    Ginny C- Perhaps slip trailed petal outlines with a “cloudy” clear (much like the ones complained about in other threads) to fill the petal shapes? Just a thought- Fred frosty? Can’t remember the descriptor used-somebody help?
  11. Weight/size Charts?

    Joseph- You said: “ I didn't realize when I had bought the clay that the shrinkage rate was so high! Talk about nightmare. Not only is that clay more expensive but you have to use more of it.” A conspiracy? Wasn’t it said that the cleanup was a bear? Wonder if they’re highly invested in cleaning products as well?

    Cabako- It's not just the UV that you need to block, but also infrared light. Might want to heed the advice given here. Respectfully, Fred
  13. Cone 6 Albany Slip Recipes

    GreyBird_ Sent you a PM with some further information. Regards, Fred
  14. Cone 6 Albany Slip Recipes

    GreyBird- If you want the recipe that Oldlady provided to add up to 100%, the the recipe would read as follows: 78% Albany Slip 22% Colemanite I'll check my recipe database in my computer when I get home to see if I have any other ^6 recipes with Albany. No promises that I'll find any, but I'll check. Hope this helps. Regards, Fred
  15. Lowering Coe?

    JohnnyK- Coefficient of thermal expansion. The reversible expansion of a material as one heats it. Not to be confused with shrinkage, which is a "one time" event.
