How to plan glaze line blends

Choose one variable and set equal steps between two end points. Five levels from 0% to 10% are 0%, 2.5%, 5%, 7.5% and 10%.

Procedure

1. Choose one variable and set equal steps between two end points. Five levels from 0% to 10% are 0%, 2.5%, 5%, 7.5% and 10%.
2. Keep test mass, mixing order, sieve, body, application and kiln position identical so only one variable changes.
3. An attractive result is not automatically safe for functional ware. Stability, fit and use need separate testing.

• Changing several variables at once without a control sample.
• Missing batch, cone or kiln-position information.
• Treating an estimate as a guarantee.
