Registration is now open with the sign-up sheet on the whiteboard in the kitchen.

Most clays are suitable, particularly those containing some grog. The Atelier clays and terracotta
work well. Note that fine clays such as PW20 may sometimes crack due to the thermal shock.
No flat plates and nothing too big - 300mm maximum height.

What is Raku?
Raku pottery, originating from traditional Japanese ceramics, offers a captivating journey into artistic expression. Here's a brief overview:

- Definition: Raku involves a low-firing process inspired by Japanese tradition. Pottery is removed from the kiln at a vibrant red heat and placed into containers filled with combustible materials. Upon ignition, the containers are sealed, creating an intense reduction atmosphere that influences glaze and clay colours. The deliberate thermal shock induces crackling, adding to the aesthetic appeal.

- Origins and History: Rooted in Buddhist practices, particularly the tea ceremony, raku embodies simplicity and naturalness. It harmonises with nature's elements, symbolising a union of earth, fire, air, and water. Intriguingly, "raku" translates to "happiness in the accident," reflecting its organic and spontaneous nature.

- Clay and Glazes: While various clays can be used, specific raku clay yields optimal results due to its thermal shock resistance. We recommend consulting our Clay Team for advice on clay selection. Additionally, choosing suitable glazes is essential, with our club offering a range of raku glazes for experimentation.

- Functional vs. Decorative: Despite its historical significance in tea ceremonies, raku pieces are primarily decorative due to their porous nature and susceptibility to glaze flaking. It's important to note that raku ware is not food-safe. Consider sealing your end product with liquid wax to enhance its durability and aesthetic appeal, adding an extra layer of protection.

Safety Measures
Ensuring safety during the Raku pottery process is paramount. Here are some essential precautions to consider:

- Attire: Wear protective clothing such as long trousers, closed-toe shoes, and long-sleeved shirts or arm protectors to shield against heat and potential hazards. Avoid loose clothing and tie back long hair or wear a hat to prevent accidents.Wear long leather gloves to protect your hands from heat and potential burns. It's crucial to keep these gloves dry, as wet leather can conduct heat and compromise protection.

- Kiln Safety: When opening the kiln, avoid leaning over it as hot air escapes, posing a risk of burns. Maintain a safe distance from the kiln and use specialised equipment like long tongs to handle red-hot pottery with care. Prior to the actual firing, practice handling the pottery with the long metal tongs to familiarise yourself with the process. Since we operate outdoors, be mindful of wind direction to avoid inhaling fumes when opening kilns. Position yourself upwind whenever possible to minimise exposure to fumes.

By adhering to these safety protocols, you can fully enjoy the enriching experience of Raku pottery while prioritising your well-being and that of others.
