  1. Duney is a nice yellow ^9/10 reduction glaze Neph Syenite 71.5 Dolomite 23.5 Ball 5 add Zircopax 7-9 Bentonnite 2.5 Red Iron Ox. 1.3 I know it looks like a weird recipe and I remember it does run when thick, but is beautiful. r

    I guess I really didn't have a name for it sager/redart or redart/sager?? I don't think sager is usually referred to as xx. I am sorry I am not a big standard fan, so I am not sure what 266 is. r

    Here is a nice example. Choy Blue Celedon ^9/10 Custer 50 Whiting 6.2 EPK 6 Flint 22.80 Barium Carb 15 add Red Iron Oxide 1.00 Barnard 1.00 The color in this glaze is from the iron in a reducing atmosphere, and suspended bubbles in the glaze, but if not reduced it will not look blue. All the ingredients in the glaze are very white, (w/o iron). Glaze recipes are based on eutectic, that is how a combination of ingredients causes melt not just the individual materials melting point. one of the things clay does in a glaze is keep the glass, (glaze) from running off the piece. It adds Aluminum which is the most refractory-takes the most heat to melt-however clay can also contribute other qualities, like iron for color. Since the clay in the recipe is EPK and only 6% a fun substitution to try would be redart for all or part of the EPK. You then could reduce the amt of RIO and Barnard. Just something fun to try. Rcts

    You are most welcome! Please let us know how the project turns out and how you like the clay.

    Redart doesn't act like a true earthenware clay. It is closer to a stoneware. Check out the AP green material list or other source. It is assumed that it is an earthenware because of the high iron content. Unless you fire in reduction it can go quite high. It also can be a very nice substitute for OM4 or EPK in glazes especially if you also need a bit of iron. Old Ladys 2 part clay recipe of XX Sager and Redart was my "invention". I needed an easy and cheap clay for students at LFCC. We needed to be able to make it in the studio. I did a few tests after reading an article of Vals on switching to cone 6. Sager gives it a little tooth but it is still very smooth for beginning throwers. We even rakued it. At cone 6 it fires a nice rich orangey brown. The iron helps activate copper and cobalt glazes providing good visual texture.
