Sgraffito: Scratching the Surface of Pottery Art

Sgraffito, derived from the Italian word “sgraffiare” meaning “to scratch,” is a pottery decorating technique with a history as rich and layered as the designs it produces. It involves applying contrasting layers of colored slip, which is liquid clay, or glazes to a ceramic piece and then carefully scratching through the top layer to reveal the color underneath. This creates intricate designs and textures, opening up a world of artistic possibilities on the clay surface. The beauty of sgraffito lies in its ability to create bold and elaborate designs, captivating both the artist and the viewer with its aesthetic appeal and the skill required to bring it to life.

The roots of sgraffito run deep, with early examples dating back to the Etruscans and Romans around 700 BCE in the Mediterranean region. The technique gained prominence during the Middle Ages, especially in Byzantine art, and later flourished in Renaissance Italy, particularly in Northern regions like Ferrara. Between 1440 and 1520, Ferrara became a hub for sgraffito pottery, producing plates and vases that depicted everything from court dramas to scenes of daily life, inspired in part by the Ecumenical Council of 1438. Islamic potters also widely used sgraffito techniques, which then spread throughout the Middle East and into Europe via Spain, influenced by migrations from Northern Africa. Even in colonial America, German settlers were producing sgraffito pottery as early as 1735, bringing their cultural heritage to their new home.

“Sgraffito… invites you to scratch the surface and reveal the beauty within.”

To try sgraffito yourself, you’ll need a few key tools and a bit of patience. In pottery, the process typically starts with a piece of leather-hard clay, meaning it’s firm but still moist enough to work with. A base layer of contrasting slip is applied, and once it sets, you can use various tools to carve through the slip, exposing the clay beneath. These tools can range from specialized pottery tools like pin tools and loop tools to everyday objects like needles or even toothpicks. The key is to use tools sharp enough to scratch through the top layer without damaging the clay body. After carving your design, the piece is left to dry completely, then bisque-fired, glazed, and fired again to complete the process.

• Leather-hard clay: Firm but still moist enough to work with.
• Contrasting slip: Applied as a base layer.
• Carving tools: Pin tools, loop tools, needles, or toothpicks.

Experimentation is key in sgraffito. For colored slips, you can add oxides or stains to a basic slip made from dry clay and water. For instance, red iron oxide, manganese dioxide, and cobalt carbonate can be added for a black slip, while cobalt carbonate alone creates a blue hue. When applying the slip, ensure each layer dries before adding another to prevent colors from mixing. Design ideas are endless, from combining sgraffito with stencils for bold contrasts to layering multiple colors of underglaze for multi-dimensional surfaces. Whether you’re drawing inspiration from Zentangle patterns or creating your own custom tools, sgraffito offers a unique way to express yourself and add depth and character to your ceramic art.

Today, sgraffito remains a beloved technique among ceramic artists worldwide, with contemporary artists like Michael Lentz, Sabina Puppo, and Michael Janis using it in innovative ways across various mediums. Whether you’re drawn to its rich history or its potential for modern expression, sgraffito invites you to scratch the surface and reveal the beauty within.
