Ceramics Failure Analysis & Formulation Optimization
Diagnose ceramic failures and optimize formulations for production-ready results
What You Can Do
This skill analyzes ceramic defects and failures, identifying root causes from thermal stress to glaze chemistry issues. It optimizes formulations for strength, durability, and aesthetic quality, and provides actionable troubleshooting workflows for production environments.
Features
systematic diagnosis of cracks, warping, dunting, and surface defects
correlates defects to clay body composition, glaze interaction, or firing conditions
adjusts material ratios (feldspar, silica, clay) for improved performance
evaluates expansion/contraction compatibility between clay and glaze
suggests temperature curves and hold times based on clay type
diagnoses crawling, crazing, pinholing, and color inconsistency
step-by-step testing protocols for mechanical strength and durability
converts lab formulations to production batches with tolerance tracking
Example Output
Example 1: Defect Analysis
Input: "We're seeing dunting (stress cracks) in our stoneware kiln load after firing"
Output:
- Root Cause: Likely rapid cooling in post-firing (kiln not venting properly)
- Contributing factors: Kiln humidity, thick-walled pieces, heating/cooling rate
- Fixes: Extend cooling by 4–6 hours, increase kiln ventilation, reduce wall thickness in high-stress areas
- Verification: Fire test batch with adjusted parameters, inspect under magnification
Example 2: Formulation Optimization
Input: "Current clay body is too soft and warps in high-fire reduction"
Output:
- Current formula: 50% kaolin, 30% feldspar, 20% silica (cone 10)
- Optimization: Add 5% grog (200 mesh), reduce feldspar to 25%, increase silica to 25%
- Expected outcome: 15–20% reduction in warping, +18% dry strength
- Test plan: Fire cones 9–11, measure dimensional change and bend strength
- Production batch: 1000 kg formula with 50 kg buffer for rounding
