How it compares

How to use it

1. Cut the desired amount of clay using a wire tool from the 12.5kg block.
2. Wedge the clay thoroughly on a plaster or wooden board to remove air bubbles.
3. Centring on the potter's wheel is straightforward due to its high plasticity.
4. Allow your creation to dry slowly under plastic to prevent warping.
5. Bisque fire at 1000°C before applying vegan-friendly glazes.
6. Perform a final glaze firing between 1050°C and 1250°C for best results.

As highlighted in reports by Ethical Consumer (2024), the shift toward circular economy products in the arts sector is vital for reducing mining impact. The durability and performance of Sio-2 products have also been noted in sustainability roundups by The Guardian (2025), which praised the brand for its transparency in raw material sourcing.

FAQ

Is Sio-2 Sio-Recycla suitable for food-safe items?

Yes, this clay is entirely suitable for creating food-safe ceramics such as plates and bowls. However, you must ensure that the glazes you apply are also lead-free and food-safe. Once fired to the correct temperature, the recycled body is stable, non-toxic, and perfectly safe for domestic kitchen use.

Does recycled clay perform differently in the kiln?

No, Sio-2 Sio-Recycla is engineered to match the thermal expansion and shrinkage rates of standard stoneware. You will not need to adjust your typical firing schedules or kiln programmes. It handles the stresses of both bisque and glaze firings with the same resilience as high-quality virgin clay bodies.

Is this clay suitable for hand-building?

Yes, it is excellent for hand-building techniques such as coiling, slabbing, and pinching. The clay's fine texture and high plasticity mean it holds its shape well without sagging, making it a versatile choice for sculptures. UK artists often prefer it for larger pieces where structural integrity is a primary concern.
