Raku is a time-honored and dramatic ceramic process best suited for advanced users. Amaco"s Raku Series Glazes are formulated to create dazzling effects and varied surfaces on non-functional pottery and sculpture. No two pieces will ever be the same as the metals and colorants of the glazes are brought to the surface by flame and reduction. Please note: firing Raku is an action-filled procedure. Two or more persons are needed to unload and reduce the Raku pieces. Heat and firepoof protective clothing, high temperature gloves and respirator are required. Raku can be safe and exciting when the right precautions are taken, but raku is not for children. This technique is for advanced high school students and older only. Restricted from use grades K-6.
