#41 In This Issue * Raku in the News – William K. Turner * Pottery Business Available - Utah ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~ * How'd they do that? A while back I had a reader send me a photo of a glaze with the hopes that someone would know a recipe for the glaze. The picture can be seen at: http://www.garyrferguson.com/justrakuarticles/misc/zion_mystery_glaze.htm Well another reader saw the picture and had a new question: "How did she get the coppery lines affect?" It is a great affect and this result (or something similar) could be achieved relatively easily. First the piece is covered with a glaze, generally quite thin. This is often done via spraying or dipping the piece. Then another glaze is drizzled over the first glaze, which is much thicker. Now the second glaze may be the same glaze or it may be a completely different glaze. Often a matte or semi-matte glaze is used as the base and a glossier glaze is the one drizzled over the top. Because either a thicker layer of the same glaze (or a different glaze) is used, it reacts differently to the reduction process than the base coat glaze. You will typically either get a base glaze with more copper than the dripped glaze or the dripped glaze will have more copper than the base glaze (as in this example). This is a great area to explore, overlapping two or more glazes on the same piece. As always, test, record, and test some more.
