Suggested materials used to make washes include: soda ash, salt, borax, and lithium carbonate. The 1 to 3 ratio is more concentrated and produces more noticeable results, while the 1 to 6 ratio is more diluted and produces softer, subtle changes in surface, color, and texture. Washes are used at varying concentrations: most commonly 1 part material to 3 parts water or 1 part material to 6 parts water. Washes are most often used in low-fire applications, but some artists also use them in mid-range and high-temperature firings, where the firing process provides the additional surface reaction, rendering the wash layer less necessary. WashesĪ wash, in this context, is a flux material mixed with water that’s applied over terra sigillata before or after the bisque firing. While a wash, or flux wash, adds a sheen and sometimes texture to the terra sigillata surface, a patina enhances the terra sigillata surface because it’s a thin, colorant-rich wash layer that settles into the subtle markings on a surface. Washes and patinas offer ceramic fired surface options that provide variations in texture and colors when applied over a terra sigillata. With these inherent qualities, terra sigillata lends itself to being adaptable to layers of additional materials, which creates a multitude of potential results from the combination of a few materials. Other desirable traits of terra sigillata include its thin, skin-like covering and its reactivity to other materials and firing processes. As a result, this uniform color can flatten the volume of a given form or, conversely, the flatness of the terra sigillata color can be used to color block areas, highlighting the form. One of the characteristics of terra sigillata is the uniform opaque color created when it’s applied in multiple layers.

We use patina color options on our steel, zinc and galvanized products. The beauty of using patina on our products is that no piece is exactly the same depending on how the metal or zinc takes the patina when applied. So instead of having a solid painted product, you can choose the patina option where you keep that industrial/metal look over time while still attempting to match your current home decor. Using this process, it creates a weathered appearance on the metal or zinc which will continue to change over time. When exposed to the elements, a coating of various chemical compounds, such as oxides and carbonates form on the surface. Patina is a tarnish produced by chemical processes that forms on the surface of many types of metals. The best way to explain it is that it’s a “process.” Just like things age over time, a patina finish put on metal/steel or zinc processes to bring out the raw metal textures, color and enhances the current metal look. One of the most popular questions we’re getting right now is what exactly is “patina?” Our summed up version and definition is “purely awesome character that stands out from the crowd.” But the technical explanation is this –
