The QUARTZ Corp's products are produced to the highest international quality standards (ISO 9000:2008), ensuring absolute consistency.
Testing starts while our raw materials are still in the ground: Our geologists have detailed knowledge surrounding the extent and quality of our deposits. After extraction the materials are tested at several stages through the manufacturing process, with final tests being done on the finished material. Analysis at every stage allows us to make adjustments to the processing conditions, ensuring that The QUARTZ Corps products are always of the highest quality
Quality control of chemical content and grain size distribution is undertaken in a modern laboratory at the plant in Drag. Analyses of the quartz products require strictly controlled processes, where the material is dissolved before the impurity levels are measured by ICPms (Mass Spectrography) instruments.
All our products are verified for key properties relevant to their intended industries to ensure that they conform to the required specifications.
