The main difference between porcelain and fine bone china is the inclusion of up to 50 percent bone ash in the porcelain mixture that makes up bone china. China is also typically fired at a lower temperature than porcelain, which is double-fired at very high temperatures. Keep Learning.
Where Porcelain becomes vitrified during the second firing (second firing is hotter than first firing), china ware is vitrified during a single firing. With the china, there is only a single firing. Generally, the temperature of this firing of china is a little less that that used for porcelain. the resulting finish is more warm in color than porcelain. This lower firing temperature finish may make china slightly more easy to decorate than porcelain.
