Rockworks Mines Private Limited supplies quartz lumps harvested from its own quarry in Bangalore, Karnataka, India. The mineral consists of silicon dioxide (SiO2) with a purity that varies between 98 % and 99.9 % as confirmed by the supplier’s analysis. Chemical analysis also shows iron content not exceeding 0.01 % and a Mohs hardness of 7 to 7.8, indicating a hard, glass‑like material. The specific gravity of the lumps is reported between 2.80 and 2.90.
Four grades of glassy quartz are produced at the mine, each meeting the requirements of different industrial sectors. Typical quartz lumps have a particle size that falls in the 10 mm to 30 mm range and are supplied in bulk containers or 1‑tonne big bags, a standard practice in the mineral trade. The low alkali and trace impurity levels align with the specifications used in glass melting and ceramic formulation. Industry standards often require a moisture content below 0.5 % to avoid defects, a condition that the supplier monitors during processing.
Primary buyers include glass manufacturers, ceramic producers, ferro‑alloy smelters and foundries that need a reliable source of silica. The lumps are shipped in sea freight containers, and the supplier is prepared to discuss Incoterms and payment methods directly with the importer. Prospective purchasers should confirm the exact grade, packaging size and any required certifications before placing an order.

Before placing an order, importers should verify the supplier’s business registration, trust‑tier status and any available third‑party audit reports to ensure legitimacy. Request a recent assay certificate that confirms SiO2 purity, iron content and moisture levels, and ask for a sample if possible to validate the material against your own specifications.
Logistics for quartz lumps from India typically involve loading the bulk containers or big bags onto a vessel at the nearest Indian port. Confirm the Incoterm (for example FOB Chennai or CIF Mumbai) and agree on payment terms such as T/T or LC before shipment. The supplier has not published lead‑time estimates, so ask for the expected dispatch schedule and any storage requirements at the port.
Quality control for industrial quartz commonly includes visual inspection, chemical analysis for SiO2 content and moisture testing. Request the latest test report from an accredited laboratory and consider arranging a third‑party inspection at the loading port. Documentation such as the certificate of origin and material safety data sheet should also be obtained to satisfy customs and downstream processing needs.
