(Porcelain / GVT Production Line – Middle East)
📈 Results (Within 60–90 Days):
✅ Rejection rate reduced from 6.5% → 4.4% (~32% drop)
✅ Visible reduction in black spots & shade variation
✅ Improved whiteness (higher L value consistency)
✅ Fuel savings due to stable firing cycles
✅ Better glaze-body interaction → improved finish
🔍 The Problem:
A leading GCC tile manufacturer producing Porcelain & GVT tiles was facing:
❌ 6.5% average rejection rate
❌ Shade variation across batches
❌ Black specks impacting export quality
❌ Inconsistent firing cycles → higher fuel consumption
📊 Root Cause Analysis:
Independent lab + plant trials identified:
• Fluctuating Na₂O / K₂O ratios in feldspar
• Higher Fe₂O₃ content → discoloration defects
• Inconsistent particle size distribution
• Batch-to-batch variation in raw material supply
👉 Conclusion: Raw material inconsistency was driving production loss.
⚙️ Solution Implemented:
Switch to controlled-grade Potash & Sodium Feldspar with
✔ Low iron content
✔ Optimized particle size (200 / 325 mesh)
✔ Consistent batch supply
💸 Business Impact:
• Thousands of sqm saved per month
• Lower cost per tile
• Improved export acceptance rates (UAE / Saudi markets)
• Stronger positioning in premium tile segment
📦 Our Feldspar Advantage:
• Engineered for Porcelain, GVT, PGVT & Vitrified tiles
• Consistent Na₂O / K₂O ratios
• Low Fe₂O₃ → cleaner, whiter tiles
