  1. Jafa5 -- Have you tried a simple ash glaze made up of 50% ash and 50% red clay? This is a recipe given by Simon Leach and works very well for me. My ash is usually a wet slurry so I just estimate equal parts of ash slurry and red clay slip. Very stable and looks great.

    help with aesthetic for pottery

    Your post caught me eye because it sounded just like me a few months ago. I too was having trouble getting the right "look" with the pots and glazes I was using. My taste was not quite as rustic as yours but somewhat similar. All of my results looked like summer camp projects - shiny and bright, but no character. I have now found some good answers that I offer for your consideration: Go to glazy.org and look around. Look at the nuka glazes and ash glazes and stoney glazes . Consider making your own glazes. Its not hard. You can order what is needed from the pottery supply stores. I recommend trying ash glazes. A good ash glaze can be made very simply by mixing equal parts wood ash and red clay slip. Try oxides as additives to a base glaze. I highly recommend a matte base glaze called "V C matte base" (see glazy.org) it has a great texture, stable, and can be mixed with different oxides and mason stains to produce a wide variety of subtle colors. Dont be afraid to "rough up" your wheel thrown pots. They can be made to look like handbuilt by warping and altering them after thrown. Good luck!
  3. The attached photo shows a glaze application that I do not understand how to recreate. Its similar to a well known area potter (McCarty Pottery, Marigold MS) in that the surface appears multi dimensional (?). In other words, the surface seems worn there are seemingly random areas that have a thicker or thinner application or slightly different colors or shades. Love the effect but completely clueless as to how to re-create. Can anyone enlighten me?

    Terra sig density

    I need advice about terra sig. What do you do (or what CAN you do) AFTER applying and polishing the piece with the terra sig? Are they bisque fired only? Can they be glazed and fired to cone 6? How do you maintain the beautiful texture and sheen that the raw terra sig piece has but still get a functional piece of stoneware?

    Terra sig density

    Well ... they are beautiful, but rough textured. The oxides look great but look like they lack a coat of smooth glaze. What I dont understand is how a terra sig piece gets "finished out". Do you just bisque it and then it is finished or do you glaze and fire again? If there is no 2nd firing then its not particularly useful is it? I would like to find a way to maintain that beautiful texture and shine that you get after app;lying and polishing the terra sig, but also to have a durable piece of stoneware. Ideas?

    Terra sig density

    Well, I guess we are about to find out. I have 4 pieces cooling right now. They are (were?) high fire clay (Standard 306) covered with terra sig (with added oxides for color) and fired to Cone 6.

    Terra sig density

    Fascinated by terra sig! Have made and applied some with good result but now am ready for the next step and I realize that I do not see any instruction regarding firing. I think I understand that the terra sig is an alternative to glaze so that it is now ready to fire with nothing more added. Correct? Do I fire to bisque temp (cone 06) or to final temp (cone 6)?
  8. All excellent suggestions, thanks.

    Deflocculate Or Add Water?

    What a wonderful resource this is! Thanks to you both.
  10. I need advice on plate making. I throw the plate with the desired angle to the rim, but as it dries the rim lifts and the plate becomes "bowl like". Suggestions?

    Deflocculate Or Add Water?

    Adjust the clay? Do you mean add kaolin?

    Deflocculate Or Add Water?

    Dick Thanks so much for the very clear explanations. (Although the whole subject still makes my head hurt!) Just to make sure I understand: if the problem I have is a "hard pan" at the bottom of my glaze, deflocculation has occurred, correct? If so, what about adding Bentonite to the recipe? Is that another solution to the problem? Or did I dream that?

    Blistering / What Causes it?

    Standard 112 and 306. US

    Blistering / What Causes it?

    Sorry -- no idea on the formula. I fire to cone 6. BTW, the picture is deceptive as to color. It is a light green with a hint of blue in it.
  15. Can anyone tell me why I am getting blistering at the bottom (only) of the piece when using this homemade glaze? Its called Westcountry Water and is: Silica 36 Potclays/BPS High Alkaline Frit 30.5 Devon China Clay 20 Gillespie Borate 12 Whiting 1.5 Total Base Recipe 100 Zircopax 4 Bentonite 3 Copper Carbonate 2 Total 109 Otherwise, a very satisfactory glaze.
