Here are the why and how, also the the time, an excerpt and the site:The case of Nippon or Japanese Porcelain marks is a bit more peculiar. The word "NIPPON" is the official name of the country of Japan and Japanese makers and trading companies initially marked their porcelain with the name Nippon. However, in 1921, the US Congress requested that Japanese Customs Authorities change the name to JAPAN. Therefore, Porcelain and China antiques that are marked "NIPPON" were made prior to 1921 and items that are marked "JAPAN" were made after 1921. Furthermore, most Porcelain and Chinaware imports from Japan were rarely marked with the actual manufacturer's mark.* http://www.marks4antiques.com/Identify-Porcelain-Antiques.htm

Identifying the difference between bone china glassware and porcelain glassware is useful for both home users and hospitality businesses. Although both are forms of ceramic, the materials, appearance, and feel make them easy to tell apart when you know what to look for. The first major difference is translucency. Bone china contains bone ash, giving it a light and delicate appearance. When you hold bone china against a bright light, you will notice that some light passes through it. Porcelain, on the other hand, is more solid and opaque. It does not allow light to shine through easily. This is often the simplest way to identify the two. Another clear difference is weight. Bone china is lighter and thinner, yet still strong due to the bone ash content. Porcelain is heavier, thicker, and feels more robust. People often recognize porcelain from its slightly cooler white tone, while bone china has a soft, creamy shade. You can also try the sound test. When tapped gently, bone china produces a long, bell-like ring. Porcelain creates a shorter and duller sound. This method has been used for years by collectors, hotels, and restaurants to quickly judge the material. Durability also varies. Bone china is chip-resistant but more delicate in everyday handling. Porcelain is tougher for regular use and offers more weight and stability, making it suitable for both home and commercial kitchens. For people buying kitchenware, this knowledge helps in choosing the right material for their needs. Many hospitality and retail suppliers—such as Bharat Glass and Crockeries, IKEA, Lifestyle Home Centre, and Pantaloon Home—usually carry both materials, and understanding the difference makes selection easier without turning it into promotional advice.
