Raku is a low-firing process originally inspired by traditional Japanese techniques, particularly those associated with the Japanese tea ceremony and Buddhist philosophy. Western-style raku typically involves removing pottery from the kiln at bright red heat and placing it into containers filled with combustible materials. As these materials ignite, the containers are sealed, creating an intense reduction atmosphere that alters the colors of glazes and clay bodies.

The rapid cooling and drastic thermal shock inherent to the process often result in crackling—deliberate cracks that add texture and visual interest to the piece. While the original Japanese raku was shaped by spiritual and cultural influences, the Western adaptation focuses on the dramatic effects produced by this high-risk, low-firing technique.

• Participants may bring up to 8 pieces, each no larger than 11 inches in height and 8 inches in diameter. Please note that Raku-fired pieces are not food safe.

• You will have access to 12 different specialty Raku glazes, including Alligator Skin, Blue Crackle, Chameleon, Copper Matte, Copper Penny, Higby Water Blue, Imperial Blue, Gun Metal, Shogun, Moon Dust, White Crackle, and Raja.

• Additionally, participants can experiment with “Naked Raku” slip, “Terra Sigillata” (for greenware, pre-bisque firing), and “Horse-Hair” applications.

• The workshop includes 4 to 5 firings in a state-of-the-art Laguna Raku Kiln and post-reduction chambers. You may also bring your own combustibles to experiment with different atmospheric surfaces.

• Food and beverages will be provided, and full staff support is available when needed.

• Please ensure all work is glazed and placed on the labeled shelving by Saturday night before the Sunday Raku firing. The glaze must be fully dried before entering the kiln. If you need assistance, staff will be available to help.

• Firings will take place in the parking lot.

• We will provide safety goggles, flame-resistant gloves, aprons, trash cans, glazes, and tongs. All shared gear will be consistently sanitized and disinfected. Feel free to bring your own protective equipment if preferred.

Due to high demand and the time required for participants to prepare their work, we kindly ask that cancellations be made at least two weeks prior to your scheduled Raku firing in order to receive a full refund.

Cancellations made within two weeks of the scheduled firing will only be eligible for a 50% refund.

Unfortunately, we cannot offer refunds for cancellations made within one week of the firing date. We also do not transfer or hold credits.

Thank you for your understanding and cooperation.

1. How often do you have Raku firings?
   We hold Raku firings 2-3 times a month.

2. Can you bisque my pieces for me before the Raku firing? If so, how much will it cost?
   Yes! We’ll be happy to bisque your pieces at no additional charge. Just bring your greenware in no later than Monday of the week of your scheduled Raku firing. Your bisqued work will be ready by Wednesday afternoon, and you can glaze it on either Friday or Saturday before the Sunday Raku firing.

3. Do you offer private Raku firings?
   Yes! We offer private Raku sessions for $500 for 4 hours. Additional hours are $200/hour.
   For more information on booking a private Raku firing, please email hello@gbclayhouse.com.

4. What kind of clay can I use for Raku?
   Any clay body above cone 5 will work, but we recommend using one that contains sand or grog to better withstand thermal shock.

5. Do my pieces have to be bisqued ahead of time?
   Yes, all pieces must be bisqued prior to the Raku firing. Please, no greenware.

6. When can I come in to glaze my pieces?
   We’ll send out an email to all Raku participants on the Monday before your scheduled firing, providing details on glazing days (usually Friday or Saturday before the Sunday Raku firing). If you can’t make those days, reach out to us, and we’ll work to accommodate you on another day.

7. Do you provide horsehair or slip for naked Raku?
   Yes, we do!

8. Can I bring my own combustibles?
   Feel free to bring your own combustibles. Our team will check if they’re suitable for use.

9. Can I use my own Raku glaze?
   Yes! Just be sure to apply your glaze at least 24 hours before the firing to ensure it’s completely dry. We recommend bringing your glaze to the studio on glazing days so you can apply it here and have it ready for the Sunday firing.

10. Are your Raku firings open to the public?
    Yes, absolutely! We love welcoming new friends.

11. I’m signed up for a Raku firing; can I bring a friend?
    Yes, but your friend can only attend as a spectator. We won’t be able to fire their work unless they are signed up for the session.
