| MODEL NO. | Product Type | Advantages | Enameling Process | Firing Temperature |
| L03-A697 | Enamel Powder | Cobalt Blue; excellent adhesion; fine and smooth enamel surface with excellent glossiness; excellent flowability and retentivity | Wet Dipping Enameling Wet Spraying Enameling | 850～860℃ |
| L03-A57 | Enamel Powder | Cobalt Blue; excellent flowability and retentivity | Wet Dipping Enameling Wet Spraying Enameling | 850～860℃ |
Often due to insufficient sandblasting or low firing temperature.
Excellent adhesion and a high thermal expansion coefficient.
Localised shrinkage or island-like patterns may result from incomplete surface preparation or excessive local enamel thickness.
Caused by insufficient firing temperature or inadequate holding time, leading to dull surfaces, bubbles, and poor adhesion.
