Fired Glaze Color in Ceramics: Testing & Analysis

Fired Glaze Color in Ceramics: Testing & Analysis

To test the colour of the glaze, a square-shaped dried clay piece is glazed using either the spraying or dipping method and then fired. A spectrophotometer is used to check the LAB value, and the delta E value is calculated to understand the colour difference between batches. This process helps ensure colour consistency.

Please refer to the raw material testing procedure for detailed steps on the colour test.
