Short answer: Every Claymistry plate, bowl, and mug is made without animal bone ash. The body is mineral stoneware, made of clay, feldspar, and silica, fired at high temperature up to 1200 C for strength. No animal bone, fully vegetarian, Jain friendly, and vegan.
In plain terms: Claymistry dinnerware is bone-ash free, which means it is made without any animal bone ash. It is plant and mineral based, so it suits vegetarian, Jain, and vegan households, and it is finished with non-toxic, food-safe glazes, cadmium free, tested at an NABL-accredited laboratory.
If you have ever flipped over a "fine bone china" plate and felt conflicted, you are not alone. Traditional bone china uses cattle bone ash in the body, typically 25 to 50 percent, and that is what gives bone china its milky translucency. For vegetarian, Jain, and vegan households, that is a hard no.
Claymistry started in 2023 with a simple brief: a daily-use Indian dinnerware range that meets three bars at once, bone-ash free, tested glazes, and priced for real Indian homes. This page is the bone-ash-free side of that story.
Bone china vs bone-ash-free ceramic, at a glance
| Feature | Traditional Bone China | Bone-Ash-Free Ceramic (Claymistry) |
|---|---|---|
| Dietary status | Contains animal bone ash, typically 25 to 50 percent of the body. Not vegetarian. | 100% plant and mineral based. Vegetarian, Jain friendly, and vegan. |
| Materials | Clay body blended with cattle bone ash for translucency. | Mineral stoneware: clay, feldspar, silica. No animal-derived material. |
| Everyday use | Thin and light, prized for translucency, and can chip at the rim. | High-fired stoneware, more chip-resistant, built for daily Indian meals. |
| Glaze | Varies by maker, and gilded pieces may need care. | Non-toxic, food-safe glaze on every piece, cadmium free and tested at an NABL-accredited laboratory. |
| Care | Hand-wash often advised, especially for decorated or gilded pieces. | Microwave and dishwasher safe on a normal cycle. |
What is bone ash, and why do most fine dinnerware brands use it?
Bone ash is the calcium phosphate that remains after cattle bones are heated at high heat. When mixed into a ceramic clay body, it does three things:
- Makes the finished piece thinner and lighter while keeping strength.
- Gives the body a warm, almost translucent white, the "holding it up to the light" look.
- Lowers firing temperature slightly, which saves kiln energy.
Those are genuine technical advantages. They are also the reason nearly every "fine bone china" brand, from British heritage names to mass-market tableware lines, still uses bone ash. "Ivory china" and "new bone china" are usually reformulations that still contain animal bone, just in smaller proportions. Check the back stamp and the fine print.

How Claymistry makes bone-ash-free ceramics that still perform
Our dinnerware is stoneware, not bone china. The body recipe is fully mineral:
- Ball clay and kaolin. The primary clay body, handcrafted piece by piece.
- Feldspar. A naturally occurring flux that fuses the body at high temperature.
- Silica. Gives the finished piece hardness and chip resistance.
Fired at high temperature, up to 1200 C, the body fully vitrifies. That means the clay fuses into a glass-like matrix with very low porosity, so stains do not soak in and it stays easy to clean and food-safe. Stoneware is heavier than bone china, by roughly a third, but it is noticeably more chip-resistant and handles daily Indian kitchen use, from stacking to microwaving to dishwashing, without complaint.
Tested glaze on a bone-ash-free body
Material ethics only work if they are complete. A bone-ash-free plate paired with an untested glaze defeats the point. Every Claymistry piece pairs a bone-ash-free body with a non-toxic, food-safe glaze, cadmium free, tested at an NABL-accredited laboratory. Lab report available on request.

Frequently asked questions
What is the difference between bone china and bone-ash-free stoneware?
Bone china contains animal bone ash, typically 25 to 50 percent of the body, which makes it thinner and more translucent. Bone-ash-free stoneware uses only mineral raw materials, clay, feldspar, and silica, fired at high temperature. Stoneware is slightly heavier but more chip-resistant and fully vegetarian. See our full ceramic vs bone china comparison for a side-by-side breakdown.
Is Claymistry dinnerware suitable for Jain households?
Yes. Our body recipe contains no animal-derived material. No bone ash, no animal fats, no gelatinous binders. Suitable for Jain, vegetarian, and vegan families.
Does bone-ash-free mean weaker?
No. Our stoneware is high-fired, up to 1200 C, which fully vitrifies the body. It is more chip-resistant than bone china in daily use and rated for dishwashers, microwaves, and ovens up to 180 C.
Is "new bone china" or "ivory china" bone-ash-free?
Usually not. Most "new bone china" and "ivory china" still contain animal bone ash, just in lower percentages. Always check the back stamp and the raw-material disclosure. If it is not explicit, assume it contains bone ash.
What about the glaze, is it also animal-free?
Yes. Our glazes use mineral pigments, such as iron oxide, cobalt, and copper carbonate, and silica-based frits. No animal-derived binders or colourants.
Can I use this dinnerware every day?
Yes, that is exactly what it is designed for. Daily meals, dishwashers, microwaves, and kids' hands. Folklore and Solitude collections are equally robust, because the extra firing fuses the pattern into the glaze rather than sitting on top.
Do you ship pan-India?
Yes, free shipping above ₹999. Free replacement for breakage in transit within 48 hours of delivery.
