This set of seven nesting bowls in blue and white is made of fine bone china with a real platinum finish. The largest has a 9 cm diameter and is 4 cm high and the smallest has a 3.5 cm diameter and is 1.5 cm high. As each item is handmade, each finish is slightly different in texture and shape. Any imperfections which may occur are because they are handmade and when working with such delicate and thin material factory perfection cannot be achieved.
Bone china is a porcelaneous body that contains calcium carbonate. This gives the ware strength and whitens it. One difference between porcelain and bone china is the whiteness of bone china. Another is the translucence of bone china: holding it to a light with your hand behind the china should reveal the shadow of your hand. Porcelain will not do so. Bone china was invented in England in the late eighteenth century and was apparently superior in strength, translucency, thinness, and whiteness to the porcelain then being produced in Europe. When comparing bone china with all other types of porcelain a difference can be noticed immediately. The body of most porcelain has an off-white greyish cast, except for some American china which is ivory colored. True bone china is almost snow-white. Bone china is far more expensive than porcelain because of its superior qualities.
