Ceramics & Glass Industry

Precision Minerals for Fired Perfection

Ceramics and glass manufacturing demand exacting mineral chemistry. We supply the feldspar, quartz, kaolin and wollastonite that power every kiln and furnace.

Our Minerals

Engineered for Ceramics & Glass

Four essential minerals that form the foundation of every ceramic body, glaze formulation and glass batch.

FeldsparSodium & Potash Grades

The essential flux in ceramic bodies — lowers vitrification temperature from >1400°C to 1200–1280°C. Forms a glassy phase that binds other components together, critical for achieving density and translucency.

SiO₂
65–70%
Al₂O₃
18–20%
Na₂O (Sodium)
7–8%
K₂O (Potash)
10–12%
Mesh Sizes
200, 325, 500
Types
Sodium & Potash
Key Applications
Tile Bodies (8–15%) Sanitaryware (20–30%) Porcelain (20–25%) Glazes (30–50%) Glass Batch (10–15%)

Quartz / SilicaGlass-Forming Oxide

The primary glass-forming oxide, providing the structural framework in both glass and ceramics. In ceramics, quartz maintains shape during firing and reduces thermal expansion. For clear glass, iron content must be held below 0.03%.

Key Applications
Container Glass Flat Glass Specialty Glass Ceramic Bodies Thermal Stability

KaolinChina Clay

Provides plasticity (workability) to ceramic bodies — without kaolin, ceramic bodies cannot be shaped. Source of Al₂O₃ that develops mullite (the strength phase) during firing. Whiteness is crucial for whiteware, porcelain and sanitaryware.

WollastoniteLow-Shrinkage Additive

Reduces firing shrinkage by 30–50% in ceramic bodies, preventing cracking and warping. Provides CaO flux at lower temperatures and is especially valued in fast-fire tile body formulations.

Quality Assurance

Tested to Ceramic & Glass Standards

Every shipment is verified against the tight tolerances that ceramic and glass manufacturers require.

Composition Consistency

XRF analysis on every batch ensures chemical composition stays within specification, critical for predictable firing behavior.

Iron Control

Fe₂O₃ held below 0.5% for white ceramics and below 0.03% for clear glass — verified by wet chemistry and XRF.

Particle Size

Laser diffraction analysis for every grade, optimized for slip casting, dry pressing or glaze suspension.

Plasticity Index

Kaolin plasticity measured via Pfefferkorn or Atterberg methods — ensuring workability in ceramic forming operations.

Fusion Point Testing

Hot-stage microscopy verifies feldspar melting behavior to guarantee correct vitrification in customer kiln cycles.
