Terra sigillata means "earthseal" in Latin. It is a very thin slip made of fine particles of clay. Apply it to bone dry clay that you have dampened a little (a spray-bottle works well). As the terra sigillata dries on your piece burnish it with a piece of an old t-shirt. You can make various colors by adding oxides and stains to the base recipe.

1. Very Earthy Green
Add 14% rutile, 4% copper carbonate.
2. Earthy Chrome Green
Add 15% rutile, 2.5% chrome oxide.

Like BB's Amazing Slip III, this slip goes on bisque or greenware. For strange effects, you can put it over glazes. It can be highfired (but be aware that some delicate stains, especially pink, will burn out at high temperature). In general, BB's IV makes more neutral colors than BB's III.
To get colors of BB's Slip IV, add one of the following variations to the basic recipe:
1. Dull Pink
Add 10% zircopax and 10% Deep Crimson Mason Stain #6006.
2. Grey Purple
Add 10% zircopax and 10% Pansy Purple Mason Stain #6385.

4. Nice Grey Blue
Add 10% zircopax and 1% cobalt carbonate.
Following is a series of washes that can be fired to cone 04. A wash should be made extremely thin, like water. Used alone, it will reveal all the texture of your clay surface. Used underneath a glaze, it may affect the color of the glaze.
All of the BB Washes are made by volume rather than by weighing, so making them is quick and easy.

This is Bettelou Brown's reformulation of the classic Jackie Rice base glaze, but without any gerstley borate in it. As of June, 2000, gerstley borate is no longer being mined. This variation preserves the waxy matt surface and the good color response of the original glaze.
BB's Crusty Cracks I - cone 04
34 magnesium carbonate
43 frit 3134
19 nepheline syenite
14 kaolin

34 magnesium carbonate
33 frit 3134
19 nepheline syenite
24 kaolin
------------------------------------------------
110
Brush on thin, one coat only!! Makes a matt surface with small cracks. If you put it on too thick, it will peel off after firing. Color: white. Try adding 15% of a mason stain for good color.

66.66 magnesium carbonate
53.34 borax
66.66 gerstley borate

This is a wild glaze. Applied thickly in just the right way, it crawls and beads for an interesting effect. The plain recipe is tan.
For the following color variations, add the specified ingredient to the base recipe:
1. Blue Bead
Add 2% cobalt carbonate.
2. Kelly Green Bead
Add 2% chrome oxide.
3. Teal Bead
Add 1% cobalt oxide + 1% chrome oxide.
4. Cracked Lime
Add 2% nickel oxide. The surface of the glaze will be a little drier - more cracked than beaded.
