How to Make Colored Pottery?
Color can be added to pottery in several ways including under glaze body color, in glaze, on glaze and additionally as a part of the glaze itself.
Nevertheless two chief types of ceramic pigment (uncooked oxide and ceramic stains) are accessible and both are widely used to produce highly decorative pottery. You can browse http://www.claygroundonline.com/ to find about pottery and how it came into light.
Knowing how and when to make use of each type will be quite rewarding, although each form of pigment has its merits. For example only adding inorganic coloring oxides such as Iron Oxide to a glaze produces color but not always the wanted color! Carry on reading to learn why.
Raw oxide pigments
It is normal for raw oxide pigments to be applied in pottery making. Many studio and craft potters prefer to use chrome oxide, cobalt oxide, Iron oxide and copper oxide as coloring pigments.
These oxides give blue, green, yellow-brown, and green- blue respectively on firing in or under the glaze. Often the fired color of the starting oxide isn't the same as the color of the fired glaze e.g. copper oxide changes from black to blue on firing in a glaze. In addition to achieve the real color impact of copper oxide an alkali rich glaze is necessary. You can gather full details about pottery making from various web sources easily.
Nonetheless combining of these oxides in a glaze, gives varying but frequently aesthetically pleasing artistic effects on firing. It is for this reason, and the lower cost entailed that these stuff are often used by many studio potters.
In contrast to raw oxide pigments, ceramic stains have been formulated to produce a broad selection of color tones in glaze. Within their manufacture they've experienced a heat process and an excellent grinding procedure so that they are exceptionally temperature stable and capable of being mixed together to create intermediate color tones. This property is highly valued by large-scale producers who want consistency of color tones. Nevertheless this comes at a cost compared to raw oxides.
