Roasted Butter Grey is a premium kiln-roasted bentonite product from Radhe Enterprise, manufactured at our Thordi, Bhavnagar facility. It is widely consumed as a traditional Indian edible roasted clay (khadi mitti, mithi mitti) — a centuries-old practice where women eat roasted clay for cravings and as a comforting snack. Our controlled kiln roasting at food-safe temperatures ensures cleanliness, purity, and the distinctive earthy aroma that consumers expect from quality eating clay.
The "butter grey" colour is achieved through precise kiln temperature control during roasting. Raw bentonite enters the rotary kiln at approximately 15% moisture and exits at below 5% after 45–60 minutes at controlled temperature. The iron content in Bhavnagar-region bentonite naturally produces the butter-grey shade when roasted under specific oxygen and temperature conditions — no artificial colourants or bleaches are used. This is a 100% natural colour transformation driven by thermal oxidation of iron compounds in the clay.
Beyond traditional edible consumption, Roasted Butter Grey serves critical applications: medical enterosorbent (binding aflatoxins, heavy metals, and pathogenic bacteria in the gut — used in antidiarrheal and detox formulations), pharmaceutical excipient for controlled drug release, fish pond sealing (sodium bentonite swells 12–15× upon hydration creating natural water barrier), aquaculture water treatment (flocculant removing ammonia, nitrite, and heavy metals), and fish feed pellet binder providing essential minerals (Ca, P, Zn, Mn, Cu) for growth, immunity, and reproductive health.

Traditional Edible Roasted Clay — Khadi Mitti from Bhavnagar
Eating roasted clay is a centuries-old tradition practiced by millions of women across India. Roasted Butter Grey, with its smooth texture and mild earthy flavour, is particularly popular as an edible clay. Our kiln roasting at controlled food-safe temperatures ensures the authentic taste and aroma that consumers expect, while maintaining the highest standards of cleanliness and purity. We supply edible clay retailers, wholesale distributors, and export buyers in retail-friendly pouches (100g–500g) to bulk bags.
Medical & Pharmaceutical Applications
Roasted Butter Grey functions as a powerful natural enterosorbent — its negatively charged surface binds positively charged toxins (aflatoxins, heavy metals like lead, arsenic, mercury, cadmium), pesticides, and pathogenic bacteria in the gastrointestinal tract, carrying them safely out of the body. It is used in antidiarrheal formulations, detox supplements, and as a pharmaceutical excipient for controlled drug release. Topically, bentonite clay masks draw out impurities, soothe inflammation, and accelerate wound healing.
Fish Pond Management & Aquaculture Feed
For fish pond sealing: sodium bentonite swells 12–15× upon hydration, creating a natural impermeable barrier that reduces water seepage — critical for fish farming in porous soil areas. For water quality: roasted clay acts as a natural flocculant, removing ammonia, nitrite, and suspended particles. For fish feed: it serves as a superior pellet binder (0.5–2% inclusion), improving water stability, reducing nutrient leaching, and providing essential minerals for fish growth and reproductive health.
Research on catfish and tilapia confirms dietary bentonite significantly improves weight gain, feed conversion ratio, and survival rates. For broodstock, the minerals (Ca, P, Zn, Mn, Cu) directly support egg quality, fertilization rates, and fry survival.
Export Documentation & Quality Assurance
International buyers receive: Certificate of Analysis (absorption, moisture, granule size, mineral profile, colour reference), Certificate of Origin (Chamber of Commerce attested), packing list with batch numbers, and fumigation certificate. For edible clay buyers, additional food-safety documentation is provided. Pre-shipment sample approval process available.

Is Roasted Butter Grey from Bhavnagar safe to eat?
Yes. Our Roasted Butter Grey is processed through controlled high-temperature kiln roasting at food-safe temperatures at our Thordi, Bhavnagar facility. Eating roasted clay (khadi mitti) is a centuries-old traditional practice — our roasting process ensures cleanliness and purity while preserving the authentic earthy aroma and texture. We recommend purchasing only from trusted manufacturers who process under food-safe conditions.
What is the difference between Roasted Butter Grey and Roasted Nakumatt?
Butter Grey is produced under oxidising kiln conditions, giving it a lighter grey colour, smoother texture, and mild earthy flavour — popular as an edible roasted clay for eating and for medical/pharmaceutical applications. Nakumatt is produced under slightly reducing conditions, giving it a darker earth tone, crunchier texture, richer mineral profile, and extra granule hardness — preferred by edible clay connoisseurs and for premium aquaculture and pharmaceutical applications.
How does Roasted Butter Grey benefit fish ponds and aquaculture?
It seals pond bottoms (swelling 12–15× upon hydration), acts as a natural flocculant improving water quality by removing ammonia and suspended particles, serves as a superior fish feed pellet binder improving water stability, and provides essential minerals (Ca, P, Zn, Mn, Cu) that support fish growth, immunity, and reproductive health.
What packing do you offer for edible clay retailers?
We provide retail-friendly pouches (100g, 250g, 500g), 1 kg, 5 kg bags for edible clay retailers and distributors, as well as 25 kg, 50 kg bags and 1 MT jumbo bags for pharmaceutical, aquaculture, and industrial buyers. Export shipments use moisture-barrier packing for ocean freight.
