Wax in ceramics is used primarily as a resist, acting as a resistant agent to prevent glazes from adhering to certain areas of a piece. Applying wax to the surface of the clay prior to glazing allows specific parts of the piece to be protected, creating detailed patterns and designs by preventing the glaze from covering the areas covered by the wax. In addition, wax is also used to protect the kiln during the firing process, preventing clay or glaze residue from adhering to the kiln's internal walls and facilitating subsequent cleaning.
Another important application of wax in ceramics is in the technique of drawing with wax, where designs are drawn on the piece with wax before applying engobes or glazes. Once the piece is fired, the areas covered by the wax remain uncolored, creating attractive visual contrasts that enhance the details of the design.
Interesting Fact
The wax drawing technique has been used in various ceramic traditions around the world, including Asian and European ceramics, allowing the creation of complex designs that combine natural resist with vibrant glazes to achieve unique artistic finishes.
Helpful Tip
For optimal results when using wax as a reservoir, be sure to apply the wax evenly and accurately over the surface of the part before glazing. Use fine tools to draw with wax and avoid overloading covered areas to maintain the integrity of the design. After applying the wax, make sure it is completely dry before proceeding with the application of engobes or glazes, thus ensuring that the protected areas remain free of color during firing.
