Warning: Firing RAKU is an action filled procedure. AT LEAST two people (preferably more) are needed to unload and reduce the Raku. You must be aware of this smoky and intensely hot environment at all times, be prepared for it and act accordingly. You must wear heat and fire protective clothing, fire proof gloves and a mask appropriate for smoke. A NIOSH approved mask like 3M’s 3600 or a comparable quality mask is recommended. Make sure you cannot smell any smoke when you have the mask on. Never open an electric kiln when the switches are in the on position. All switches must be off before you load or unload the kiln. Always use tongs to carry hot pots from the kiln or from the reduction bucket. The reduction bucket must always be outdoors. RAKU gas kilns are usually outdoors but even if you are using an electric kiln you still have to take the pieces outdoors to reduce them. Do not be concerned about the piece cooling in the process, because it will still be hot enough no matter how far you have to carry it outdoors.
RAKU can be safe and exciting when the right precautions are taken. RAKU is not for children. This technique is for adults or college students only.
