Common questions

What does Obsidian Minerals manufacture?

We manufacture and export industrial minerals — attapulgite, bentonite, dolomite, calcium carbonate, ball clay, diatomaceous earth, bleaching earth and organoclay — plus specialty chemicals such as magnesium oxide, magnesium carbonate, clay catalysts, desiccant fillers and foundry coating rheology modifiers.

Do you supply API 13A drilling grade clays?

Yes. We supply attapulgite to API 13A Section 12 and drilling-grade bentonite to API 13A Sections 9 and 11 (OCMA grade). Each lot is tested against the applicable requirements and shipped with a Certificate of Analysis.

Can I get a sample before placing a bulk order?

Yes. Samples of standard grades are available for qualification trials. Share your application and target specification through the quote form and our technical team will recommend a grade and arrange a sample with its datasheet.

Do you export outside India?

Yes. We serve customers in more than 15 countries with export-ready packaging — 25 kg and 50 kg bags or 1 MT jumbo bags — and full documentation including CoA, Technical Data Sheet and MSDS.
