At BARTON, quality isn’t just a buzzword — it’s the backbone of everything we do. From sourcing raw materials to packaging the final product, we leave no stone unturned (or garnet untested) to ensure the highest standards. If you’ve ever wondered what makes BARTON garnet abrasives the go-to choice for industries like aerospace, medical, and defense, here’s your chance to find out.

But first, let’s talk about where it all begins: our rigorous prequalification process.

Before any raw material enters our supply chain, it goes through an exhaustive prequalification process. This isn’t just done internally — third-party labs also join the effort to ensure our garnet meets the most stringent criteria. By catching potential issues like product moisture, excess fines, or inconsistent particle sizes at the outset, we guarantee a final product that delivers peak performance and efficiency.

Key properties we test include:

• Purity
• Conductivity & chlorides
• Radioactivity
• Free silica and respirable quartz

And that’s just the first step. Once the garnet passes prequalification, additional testing at our processing facilities ensures every shipment matches the high standards of the initial sample.

Every batch of BARTON garnet undergoes our strict, four-step processing method: separation, washing, drying, and screening. These steps ensure high purity and consistent particle sizing, crucial for the toughest applications. Plus, our garnet is packaged in special moisture-blocking materials to preserve its quality.

Random sample testing of finished products ensures excellence every time. We retain samples from every lot produced for an entire year. If a customer ever has a question, we can analyze the exact batch in question. It’s this kind of obsessive attention to detail that sets us apart.
