Feldspar For Tiles

Why Your Large Format Tiles are Bending 📉

Your press is calibrated. Your kiln curve is locked. Yet, your 800x800 slabs are bowing and your 1200x600 panels are lifting at the edges.
The truth? Your kiln didn't bend the tile. Your Feldspar did.

In large format production, there is zero margin for mineral error. When feldspar chemistry shifts, you get Differential Shrinkage—one zone vitrifies faster than the rest, creating internal stress that force the tile to bend.

The 3 Feldspar Killers of Tile Planarity:
1️⃣ K₂O/Na₂O Ratio Drift: Shifting chemistry = shifting shrinkage curves.
2️⃣ Inconsistent PSD (325 Mesh): Coarse particles cause localized over-firing and edge lifting.
3️⃣ Mixed Mine Sourcing: Blending different geologies leads to uncontrolled firing behavior.

Pabrik di Pasuruan & Surabaya menyebutnya "melengkung setelah pembakaran." Kütahya & Bilecik fabrikaları buna "pişirme sonrası eğilme" diyor. مصانع رأس الخيمة والرياض تسميها "انحناء البلاط بعد الحرق." Kilang di Selangor & Johor Bahru — "jubin bengkok selepas pembakaran."
Different city. Different language. Same bent tile.
