Strontium Carbonate SrCO3 Powder

Premium Strontium Carbonate (SrCO₃) – High-Purity Fine White Powder – The Safer, Brighter Alternative Flux for Exceptional Matte & Glossy Glazes

Discover the modern potter's smart choice: strontium carbonate, the preferred, non-toxic source of SrO that delivers many of barium's coveted effects with greater safety and often superior clarity. This fine, bright white powder (typically 98–99%+ purity) is a versatile powerhouse in ceramics, offering brilliant surfaces, enhanced color response, and reliable performance without the toxicity concerns of barium.

Why choose our Strontium Carbonate?

• Serves as an excellent safer substitute for barium carbonate — produce stunning satin-to-matte glazes with silky textures and subtle depth; use ~75% of the barium amount and test for color match — many artists achieve near-identical (or even brighter) results in crystal mattes, lava, crater, and dolomite-style surfaces.
• Boosts glaze brightness and clarity — increases refractive index for luminous, glossy finishes with exceptional transparency and fewer defects like pinholes or blisters (especially when sourced via frits for smoother melts).
• Enhances color vibrancy — supports rich, saturated responses from oxides like copper (vibrant blues/greens), cobalt, chrome, and iron — delivers jewel-like intensity with a cleaner, more predictable outcome than many alternatives.
• Acts as a strong flux — lowers melting points, promotes smooth flow and vitrification, reduces crazing risk by moderating thermal expansion (often lower than calcium-based glazes), and improves scratch resistance and durability.
• Smooths viscous or zirconium-opacified glazes — small additions reduce surface tension for flawless, defect-free results in opaque whites or textured effects.
• Versatile in specialty applications — modifies metallic oxide colors, contributes to iridescent or luminous effects, and finds use in glass, frits, and advanced ceramics for durability and optical quality.

Key Properties at a Glance:

• Chemical formula: SrCO₃
• Appearance: Fine, bright white powder
• Very slightly soluble (behaves reliably in slips; solubility increases with heat/CO₂ — mix carefully to avoid flocculation)
• Decomposes during firing to release SrO — the active flux — plus CO₂ (can cause pinholes/blisters in high amounts if melt viscosity is high; frit alternatives minimize this)
• Safer profile — non-toxic strontium (distinct from radioactive isotopes); ideal for food-safe pursuits when properly formulated and tested

Whether you're reformulating barium recipes for safer studio work, chasing brilliant glossy transparents, crafting satin-matte masterpieces with rich color pops, smoothing tricky opacified glazes, or exploring unique crystalline and textured surfaces, this high-quality strontium carbonate provides consistent, high-performance results with peace of mind.

Handle with standard care — use gloves, mask during dry mixing, and good ventilation (dust is minimal but always prudent); store sealed to maintain purity.
