Barium Carbonate (Withurite) Fine Powder

Premium Barium Carbonate (BaCO₃) – High-Purity, Fine White Powder – The Essential Flux for Stunning Ceramic & Glass Creations

Unlock the transformative power of barium carbonate, the go-to source of BaO for discerning potters, ceramic artists, glassmakers, and industrial manufacturers. This dense, ultra-fine white powder (99%+ purity) delivers unparalleled performance in a wide range of high-value applications.

Why choose our Barium Carbonate?

• Creates breathtaking barium crystal matte glazes — those iconic, silky, frost-like surfaces with depth and subtle shimmer that only BaO can reliably produce. Watch crystalline magic emerge during cooling for truly one-of-a-kind results.
• Acts as a powerful flux to lower melting points, improve glaze flow, enhance matte effects, and develop unique color responses when paired with cobalt, copper, iron, and other oxides — effects difficult or impossible to achieve otherwise.
• Prevents unsightly efflorescence (white salty scumming) on bricks, tiles, and clay bodies — just 0.2–0.8% addition keeps your fired surfaces pristine and professional.
• Elevates specialty glass formulations — boosts refractive index, improves clarity, chemical durability, and mechanical strength for optical, lighting, and technical glass products.
• Versatile precursor for ferrites, pyrotechnic green colorants, magnets, and more — a cornerstone material across ceramics, glass, and advanced materials industries.

Key Properties at a Glance:

• Chemical formula: BaCO₃
• Appearance: Fine, dense white powder
• Low water solubility — behaves predictably in slips and glazes
• Decomposes during firing to release BaO — the active fluxing powerhouse

Whether you're crafting museum-worthy crystalline-glaze pottery, producing durable architectural ceramics, formulating brilliant specialty glass, or working in industrial-scale production, this high-quality barium carbonate delivers consistent, reliable results batch after batch.

Handle with appropriate care — standard studio safety practices apply (gloves, dust mask, good ventilation).

Elevate your work from ordinary to extraordinary. Add this essential barium powerhouse to your materials shelf today — the secret behind many of the most admired matte and crystalline surfaces in modern ceramics!
