Raku firing is an ancient Japanese ceramics technique that has been used for many centuries to create a very unique finish to wares. The Raku technique dates back to the 16th century, traditionally crafted by hand and not thrown on a potter's wheel.

The Raku technique is essentially when glazed ceramics are taken from the kiln while they are still glowing red hot and are then placed in a material that would be able to catch fire, such as sawdust or newspaper. This technique is used to starve the piece of oxygen, which creates a myriad of colors within the glaze.
