OBSIDIAN SHELL®
Non-stick, PFAS-free
The future of cooking is free of harmful substances. OBSIDIAN SHELL® is our completely new non-stick coating based on mineral components such as corundum, feldspar, sapphire, silicon, and titanium. Completely free of PFAS, PTFE, PFOA, or other plastics.
Our technology is based on a natural phenomenon: Just like hot lava solidifying into obsidian, our dry mineral coating powder is liquefied at high temperatures and then cooled extremely rapidly. The result: an extremely robust, deep black surface with outstanding non-stick properties, completely free of toxic chemicals.

OBSIDIAN SHELL®
Here's how it works
The non-stick effect is created by a unique silicon structure that not only seals the surface but permeates the entire coating. This ensures that the non-stick properties remain strong not just initially, but consistently at the highest level throughout the coating's lifespan. OBSIDIAN SHELL® easily withstands temperature peaks of up to 450 °C – without any loss of performance and without the release of harmful substances. Unlike plastics such as PEEK or conventional ceramic coatings, its performance remains permanently stable.
Each particle fused together – for maximum durability.
Forged like lava
The exceptional durability of OBSIDIAN SHELL® is based on a special powder coating process in which the mineral components are applied as a dry powder, liquefied at high temperatures, and then rapidly cooled. Similar to solidifying lava, this creates a compact, dense, and perfectly homogeneous layer in which every single particle is firmly fused to the metal surface. This volcano-like process prevents the coating from chipping or thinning. The result is an extremely robust, durable, and high-performance coating that permanently retains its non-stick properties.
Easy to care for. Durable. Environmentally friendly.
High-tech for eternity
The OBSIDIAN SHELL® coating is not only technically outstanding but also extremely practical for everyday use. Thanks to its smooth, dense surface, food hardly sticks, making the pans easy to clean – often a simple wipe with water is all it takes. They are also dishwasher-safe and can withstand frequent washing without any loss of performance. Because the coating is permanently fused to the material, it cannot chip or be damaged. This ensures that its performance is maintained for many years. And instead of being thrown away, the pan can simply be recoated when needed – saving resources and protecting the environment.
From test winner to new benchmark
In an independent test conducted by the magazine Haus und Garten Test, our DURAQUARZ® coating was awarded the top rating of "very good." Its outstanding non-stick effect was impressive, even without added fat – no sticking, no odor, no alteration of taste. Based on this success, we developed a completely new coating technology: OBSIDIAN SHELL®. It combines everything that has made DURAQUARZ® so successful – and surpasses it significantly, especially in terms of robustness and non-stick performance. The result: a coating that is even more resistant, longer-lasting, and more effective. Or, in short: everything DURAQUARZ® could do – only better.
