from Source to Solution

Superior purity sourced directly from the earth. Proudly Product of Thailand.

Our Story

A commitment to quality at every step, managing raw purity from our mine to your refined solution.

Kaolin mines at Uttaradit

The Source: Uttaradit Mine

Our journey begins in the mineral-rich hills of Uttaradit, where Darson operates its own private mining concession.

By controlling the source, we bypass third-party inconsistencies, carefully selecting only the purest raw kaolin seams. This direct oversight ensures that every batch starts with a foundation of uncompromised quality.

Kaolin Reserve

The Refinement: Nakhon Pathom

Located at our 38,400 sqm facility, we process raw materials using advanced Dry Grinding & Ball Mill technology.

Why Alumina Balls?

Crucially, we utilize high-grade alumina balls as our grinding medium. Unlike steel balls, alumina prevents iron contamination (rust), ensuring maximum purity and superior whiteness for the most demanding industries.
