01 / PROBLEM
The Problem
A continuous glaze hairline cracking problem was plaguing export-grade vitrified slabs destined for European markets. Surface tests showed normal hardness, but after standard freeze-thaw cycles and stress testing, micro-fractures consistently appeared beneath the surface polish.
02 / INTERVENTION
The Strategic Intervention
Aakriti engineered a cross-sectional dilatometric analysis across all three firing layers: raw tile body, intermediary engobe layer, and top glaze layer. The analysis uncovered a subtle coefficient of thermal expansion (CTE) mismatch between the engobe and body.
COMMERCIAL VALUE
Restored export compliance for 1.2M sq. meters of annual production and secured recurring supply contracts across 4 European distributor networks.
03 / THE RESULT
The Result
By reformulating the engobe recipe with precise flux and silica balance, internal stresses were eliminated. The cracking stopped completely with zero rejections on European buyer compliance audits.
