212-219 - The eight colors in this series are designed to be used with our 250 Satin Clear to produce a textured and variegated surface which we call Dragon Skin. The technique requires that you first apply, on cone 03 bisque, one to three coats of the color. Let the color dry, then apply one to three coats of Satin Clear on top of the color. When the piece is fired to cone 06/05 a reaction takes place between these special colors and the Satin Clear glaze which produces the textured effect. Our samples show the results from using three coats of color and three coats of glaze. Other interesting results can be obtained by applying fewer coats of color and/or fewer coats of Satin Clear. Please do not use six coats (total) of glaze all the way to the bottom of the piece since such a heavy application of glaze will tend to move and could run off the bottom of the piece. Cut down the total number of coats to three towards the bottom of the piece. Also please note that color 218 Copper Green is significantly softer than the other colors and will tend to run more. This should be taken into account in the decoration of your piece. All of these colors are lead free. Colors 212,213,214,215 and 219 are non-toxic. Colors 216,217 and 218 are considered toxic in the liquid state due to the presence of copper oxide beyond the non-toxic limit and are therefore not suitable for use by small children or pregnant women. All of these colors are NOT considered dinnerware safe because the rough textured surfaces are hard to clean and tend to trap bacteria.
