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

Defect analysis framework

systematic diagnosis of cracks, warping, dunting, and surface defects

Failure root-cause mapping

correlates defects to clay body composition, glaze interaction, or firing conditions

Formulation optimization

adjusts material ratios (feldspar, silica, clay) for improved performance

Thermal stress calculations

evaluates expansion/contraction compatibility between clay and glaze

Firing profile recommendations

suggests temperature curves and hold times based on clay type

Glaze chemistry troubleshooting

diagnoses crawling, crazing, pinholing, and color inconsistency

Quality verification checklist

step-by-step testing protocols for mechanical strength and durability

Production scaling worksheet

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
