Key parameters include adsorption capacity, bulk density, water addition, and slurry flow (slump value).
This occurs when the workpiece is not dried promptly after enamelling, leading to uneven water precipitation patterns.
Excessive internal moisture during drying can cause vertical streaks or sagging. This is often due to high humidity or insufficient ventilation in the drying system.
Typically caused by misalignment during assembly or welding of the workpiece.
