GLR Mines And Minerals Pvt Ltd supplies quartz lumps harvested in India. The lumps contain a minimum of 99 % SiO₂, with iron oxide limited to 0.08 % and alumina to 0.03 %. Loss on ignition is recorded at 0.09 % and the material appears as clear white with a whiteness index between 95 % and 98 %. The listed melting point is -1600 °C and the boiling point -2230 °C, values supplied by the supplier.
These specifications place the product within the industrial‑grade quartz category used for glass melting and refractory applications. Typical quartz lumps in the market exhibit similar purity levels and low impurity content, which reduces discoloration in glass batches. The low iron content is especially important for producing colour‑critical glassware and semiconductor‑grade silicon. In addition, the physical appearance and whiteness meet the expectations for high‑temperature ceramic formulations.
Buyers such as glass manufacturers, ceramic producers and ferro‑alloy plants commonly request this material in bulk container loads. Trade terms are negotiated directly with GLR Mines And Minerals, with packaging generally in 20‑ft or 40‑ft containers or bulk loose cargo as agreed. As the supplier does not disclose a minimum order quantity, interested importers should confirm the MOQ, Incoterms and payment schedule with the company before finalising the contract.

GLR Mines And Minerals Pvt Ltd is located at No 1F, North Gopalapuram First Street, Gopalapuram, Chennai, Tamil Nadu, India, postal code 600018. The supplier holds a harbour‑tier verification on the platform, indicating that its business registration has been reviewed. Response metrics show a 0 % response rate and no recorded average response time, suggesting that the buyer should initiate contact and confirm communication channels. The company lists quartz lumps as its primary export commodity.
The listing does not provide details on production capacity, certifications or export licences, so importers should request those documents directly. GLR Mines And Minerals states that the lumps are suitable for glass, ceramic and ferro‑alloy applications, but no specific quality‑assurance procedures are described. Potential buyers can ask for a recent laboratory analysis report to verify the impurity levels reported. The supplier’s address places it within a major industrial region of southern India, facilitating access to ports such as Chennai.
High purity Quartz Lumps containing 99% SiO2 are a critical raw material for glass manufacturing, ceramics, and ferroalloy production. With extremely low iron oxide (0.08%) and alumina (0.03%) content, these clear white lumps meet stringent industrial grade specifications and are suitable for high-temperature refractory applications. Widely traded internationally for use in silicon metal production, foundry, and advanced material manufacturing sectors.

Before placing an order, importers should obtain a recent chemical analysis that confirms the SiO₂ content of at least 99 % and the low iron and alumina levels reported. Request the supplier’s business licence and harbour‑tier verification documents to ensure legitimacy. A sample batch can be sent for independent testing, especially if the material will be used in colour‑sensitive glass production. Verifying these data reduces the risk of receiving off‑spec quartz.
GLR Mines And Minerals typically ships the lumps from the port of Chennai, but the exact loading port should be confirmed during negotiation. Importers need to agree on Incoterms such as FOB Chennai or CIF Mumbai, and clarify the expected lead time, which is not disclosed in the listing. Payment terms are usually negotiated on a letter of credit basis, but the supplier has not published a standard schedule. Confirming these logistics details early prevents delays at customs.
Upon arrival, a third‑party inspection agency should verify the physical condition, particle size distribution and moisture content of the quartz lumps. Request the supplier’s mill test report, as well as any ASTM or ISO test certificates that cover chemical composition and thermal properties. Retaining these documents alongside the commercial invoice and packing list will streamline customs clearance and quality acceptance at the plant. Establishing a clear inspection protocol protects both parties from disputes over material quality.
