STONE Glaze Powder — Beige to Glossy Crystalline Ash-like Finish
from €25.00
A studio favorite with endlessly beautiful variations
Our signature STONE glaze is a soft, earthy beige when applied thinly, shifting into a glossy, ash-like surface where the glaze pools thicker. At the transition between matte and gloss, delicate crystalline blooms appear — subtle, light-catching patterns that evoke natural ash glazes.
On darker stoneware bodies such as Anthrazit, the glaze reveals even more depth: pale, shimmering crystalline movement reminiscent of northern lights drifting across the surface. The final shade and character vary beautifully between clay bodies — see the last images showing Anthrazit (Witgert).
This glaze is highly thickness-sensitive, rewarding potters who enjoy variation and kiln alchemy: • Thin application → matte beige • Thick application → glossy ash-like surface (some pin holing may appear when applied too thick) • Transition areas → fine crystalline development
No two firings ever look exactly the same — that’s the magic of STONE.
Recommended Firing Range
1220–1280°C (≈ 2228–2336°F) Cone 6–9 equivalent Suitable for high-fired stoneware and porcelain.
Add small amounts of water to refine thickness as needed.
Important: Mix the entire dry bag at once — because the glaze is blended by hand, ingredients are not fully uniform until the full mix is slurried.
Yield example: 500 g (≈ 1.1 lb) of dry glaze = approx. 800 ml (≈ 27 fl oz) liquid glaze.
Application Methods
Apply an even layer. Suitable for: • dipping • brushing • spraying • pouring
Results will vary depending on: • glaze thickness • clay body • firing curve • placement in kiln
Testing is highly recommended to discover your favorite variation.
Safety Information — Please Read
• Do not ingest. • Wear gloves when mixing or applying. • Keep away from eyes; rinse thoroughly if contact occurs. • Avoid breathing glaze dust; never sweep dry powder. • Clean dried glaze with a wet cloth only. • Ensure good ventilation during firing.
