How to Add Depth and Detail to Your Pots with Water Etching Annie Beggs

Water etching is a greenware surface treatment used to create relief. A water-resistant material is applied to greenware and allowed to dry. Then a damp sponge is used to gently erode the clay. The areas where the resist was applied appear raised, while areas without it recede, and the resist burns away during the bisque firing. Although shellac, wax resist, and other water-resistant materials can be used for water etching, my choice is Mod Podge® as it is an accessible, odorless, easy-to-use, and affordable modified PVA glue and sealer. 

Use a dull, soft pencil to sketch your design onto bone-dry greenware. Porcelain and other groggless clays produce smooth, clean lines. If you use textured clay, expect textured results. Add Mod Podge® to a container and dilute it with a small amount of water (1), which allows for even application. Next, apply the mixture to areas of your piece that you want to raise above the background (2). Allow the mixture to dry sufficiently. Then, use a damp sponge to wipe away the surface of your clay in gentle, sweeping motions (3), making sure to rinse your sponge frequently. Once you begin to see your design develop, let the clay dry out before continuing (4). Avoid oversaturating the clay with water, which can cause cracking at this stage. Repeat the wiping and drying process until your desired image definition is achieved. 

After firing, choose a translucent glaze to showcase subtle texture. Take this technique to the next level by incorporating underglaze before applying Mod Podge® and creating multi-depth relief.
