Resources

Our strength begins at the source.

Our proprietary mining resources in Venezuela give us direct access to white-firing clays with particularly attractive characteristics for ceramic manufacturing.

Proprietary resources
White-firing clays extracted from our own mining resources in Venezuela.
Controlled at source
Direct involvement in extraction and material selection gives us greater control over quality and consistency from the very beginning.
Traceability from source
Rigorous controls at source allow us to maintain traceability throughout the material’s development and supply process.

Handling & Logistics

From extraction to reliable supply.

Stockpiling, handling and logistics designed to protect material quality and support continuity of supply.

Lab & Tech Expertise

Quality controlled from source to formulation.

By testing the material close to the source and again at the heart of Spain’s ceramic industry, we can monitor its properties throughout the process, verify consistency and develop the right blends for each customer’s technical requirements.

This dual laboratory capability connects mineral control at origin with ceramic application expertise, helping ensure reliable quality from extraction to formulation.

Our own laboratories at the mine site and in Castellón, Spain, support quality control, material analysisand blend development.

Quality control at source
Testing at our mine-site laboratories helps verify material properties from the earliest stages of extraction.
Blend development
Our laboratory in Castellón supports the development and adjustment of mineral blends according to each customer’s technical requirements.
Consistency verification
Continuous analysis helps monitor material consistency and ensure reliable performance from batch to batch.
