About enamel mug
The enamel mug is hand-made and the process is complicated. There is no innocent saying. It is inevitable that there will be uneven glazing, dents or scratches, and black spots caused by falling ash.
1. Distinguish between porcelain and black spots
Every production process of enamel requires manual operation, which determines the imperfect characteristics of enamel. Customers who are not familiar with enamel will be entangled in small black spots inside or outside. In fact, as long as they are enamel products, there will inevitably be black spots (especially white glaze and the inside of the food utensils is a white glaze, eliminating colorants). The dust in the environment during the baking process will fall on the glaze to form black spots, which will not affect the use. Especially in the case of white glaze, the enamel products are unavoidable.
2. Folding type pit
There are several small pits in the handle of the inside of the cuffed side, the measuring cup or the baking pan. It is the mark of the hook or bracket that is hoisted or racked up during glazing, drying or firing. It can’t float in the air, this is a process limitation.
