The material of which the cups are made, can be described in many ways. Porcelain cup, stoneware? Thin-walled, warm tone or cold white? What does exactly new bone china mean?
And why porcelain is not always white?
New Bone China, it is warm white porcelain with thin wall. Decorations made on NBC mugs have soft, smooth edges.
Super White is a thin-walled porcelain with cold white color.
Stoneware is characterized by a thick wall and a little gray shade of white. Decorations made on stoneware mugs have sharp edges and saturated colors.
