If you’re looking for a way to add some unique flair to your pottery, you might want to try raku firing. Raku is a traditional Japanese firing technique that involves removing pottery from the kiln while it’s still hot and placing it in a container with combustible materials. This creates a unique, crackled glaze that can’t be replicated with any other technique. In this article, we’ll walk you through the steps to raku fire at home.
The first step to raku firing is to prepare your pottery. Make sure it’s completely dry and free of any glaze or decoration. You’ll also want to make sure it’s no thicker than 1/2 inch, as thicker pottery can crack during the firing process.
Next, you’ll need to fire your pottery in a kiln. The temperature and duration of the firing will depend on the specific type of clay you’re using. Typically, you’ll need to fire the pottery at a high temperature for several hours.
Once your pottery has been fired, carefully remove it from the kiln using tongs. Be sure to wear heat-resistant gloves and eye protection, as the pottery will still be extremely hot.
Next, place your pottery in a container with combustible materials such as sawdust, straw, or newspaper. Cover the container with a lid to prevent oxygen from entering.
Allow the pottery to cool completely in the container. This will take several hours, so be patient!
Once your pottery has cooled, remove it from the container and clean it with a soft-bristled brush. You may notice some black soot on the pottery, but don’t worry – this is normal and can add to the rustic look of your raku-fired pottery.
Finally, you’ll want to seal your pottery to protect the crackled glaze. You can use a clear acrylic sealer or wax to do this.
