Sibelco WMS2002GG Clay 10kg

Sibelco WMS2002GG Clay – speckled stoneware body with black grog

Sibelco WMS2002GG is a grey stoneware body with fine, black grog and natural speckling. Dark spots become visible from approximately 1150°C, and the body's color takes on a complex, mineral character. The body combines an interesting visual effect with a surface fine enough for throwing and everyday use.

Characteristics:

• Fired color: grey with dark spots
• Application: throwing and hand-building
• Form: plastic clay, 10 kg packs
• Firing temperature range: 1000–1250°C
• Grog content: 20% black grog, 0–0.2 mm grain size
• Drying shrinkage: approx. 6.0%
• Firing shrinkage: approx. 5.5% at 1200°C
• Water absorption after firing: approx. 2.5% at 1200°C

Recommended for functional ware, bowls, cups, vases, and slab-built forms. It looks particularly good with transparent glazes, celadons, and matte glazes that allow the body's pattern to show through. The natural speckling makes each piece slightly different, which is appreciated by creators seeking a handmade uniqueness without additional decoration.

The parameters provided are indicative. The final color, shrinkage, water absorption, and glaze behavior depend on the kiln, atmosphere, soaking time, and firing curve. Before making a larger series, we recommend a technological test with the chosen clay body and glaze.
