If you have ever done raku firing, you are probably aware that the raku firing process should not be used for pots that are intended to serve food. The rapid firing, removal of the ware at the red-heat stage, and subsequent post-firing all contribute to surfaces that remain porous after firing. So it is best for decorative pots or sculpture. If you are looking for another application for raku, today’s post just might be for you.
The Obvara technique, which originated in Eastern Europe around the 12th Century, involves scalding the finish on the pottery to seal the porous surface. Similar to the raku process, a bisqued pot is heated, in this case to 1650°F (899°C) and removed from the heat. The difference is that the pot is then dipped into a specific Obvara yeast mixture before being dunked in water to rapidly cool the piece. The effects are quite stunning.
In today’s post, an excerpt from her new video Raku Firing: Expanding the Potential of the Raku Kiln, Marcia Selsor shows how to enhance the effects of an Obvara firing by texturing the surface and then shows the exciting process.- Jennifer Harnetty, editor.

I participated in a raku firing (Western style) when I was an undergrad in one of Matt Long’s classes at Ohio University. It is no wonder raku is such a popular technique among potters and ceramic artists because what’s not to love about playing so directly with fire? But, like many ceramic techniques, it is extremely important to follow strict safety guidelines, not only to protect yourself from the open flame, but also the fumes that can damage your lungs. In today’s feature, ceramic artist and long-time raku practitioner Michael Lancaster shares some of the things he has learned over his many years of firing raku.
Naked raku gets its racy name because during the process of firing, the outer shell of slip that was applied falls off revealing the “naked” surface of the pot underneath. Charlie and Linda Riggs get some beautiful results from this technique. Today, in an excerpt from our free download Successful Tips and Techniques for Raku Firing: How to Select Raku Clays, Glazes, Kilns and Combustibles, Charlie and Linda share their technique.
Charlie and Linda Riggs began experimenting with saggar firing after being disappointed with the results of some of their pit firings. Today, the Riggs share their saggar firing process which they have tweaked and honed over the years. Enjoy!

There are all sorts of ways to use glass to embellish pottery. But I had never seen anyone inlay glass exactly like Steven Branfman does. Steven throws a cylinder and then rolls it in crushed glass. Then he continues throwing from the inside (so as not to cut his fingers!) to shape the pot. In today’s post, Steven takes us through the process step by step.
