The range of colors that may be achieved with terracotta panel are virtually endless. The material is known for its familiar red color, but its natural color variation ranges from light cream to dark grey. The addition of pigments and glazes make colors like white, yellow, blue, red, green, purple and black possible. Consult with expert manufacturers such as Paneltek terracotta panel about the many ways that you can achieve your design goals. For starters, terracotta panel can be categorized into glazed and unglazed.
Unglazed: When talking about unglazed terracotta panel, various colors can be achieved by mixing different types of clay. For example you can mix red and white clay to get lighter reds or even yellowish clays. Natural fired colors typically include white, sand, yellow, taupe and a wide range of reddish hues. To get a little bit higher variation, you can add pigments or oxides. Through firing these pigments at a temperature of about 2,000 degrees-Fahrenheit, they will react with the clay, creating stable and long-lasting colors. You will not really see a difference in color over 50 or even 100 years.
Glazed: With glazed terracotta panel you have a body color, which is typically white or off-white, and then you have a glaze that is applied to the terracotta panel before they go into the firing process. Beyond an endless library of color options, glazes give you the freedom to achieve different opacities and finishes. You can have a very transparent glaze where you still see the body color underneath or a completely opaque glaze that you cannot see through at all. You also have the option of choosing between very high gloss and completely matte finishes. By combining two or three glazes on different layers of the product, other special effects, including iridescence, are also possible.
