BODYCLAY STONEWARE GF85 (1200-1250º – 10,5 KG

Developed for discerning ceramicists, GF 85 is a high-fire stoneware clay body that combines strength, plasticity and ease of use. Its composition provides stability when creating pieces of different sizes. Versatile and easy to work with, it is suitable for both hand-building and the potter’s wheel. Its fine, smooth texture makes shaping easier, offering greater control, comfort and precision. Suitable for firing between 1200°C and 1250°C, GF 85 has a neutral grey base colour, ideal for creating contrast with high-fire glazes and other ceramic decoration techniques, giving finishes the necessary depth.
