Description
GRM – Dark brown stoneware clay with a fine structure
The fine-grained and almost grog-free stoneware clay GRM impresses with excellent workability. Its very small and fine grain portion makes it especially suitable for throwing at the potter’s wheel. This clay is also perfect for handbuilding, slab techniques or the modelling of figures.
In stoneware firings the GRM develops its characteristic dark beige firing color, which gives it a warm, natural charm. Another benefit: the iron oxide in this clay creates exciting interaction with the glazing. Even in an oxidation firing, it produces glaze effects that resemble a reduction firing – perfect for expressive surfaces and unique individual pieces.
Benefits of the GRM:
- Fine-grained stoneware clay – almost grog-free
- Excellent for throwing while also versatile for handbuilding, slab work and sculptures
- Dark beige firing color after the stoneware firing
- Intense glazing reactions due to its natural iron oxide
- Reduction-like effects in oxidation firing
The GRM opens up a world of possibilities – whether you are looking for intricate shapes or experimental surfaces, this stoneware clay offers creative freedom and high-quality results.
