How long does it take for ordinary porcelain to sinter? For example, what is the temperature of a ceramic cup? Does bone China take the same time as ordinary ceramics?

if the porcelain is commonly used, it will take about 3 ~ 4 hours to burn to about 11 degrees.

Of course, if you do it yourself, you should set a sintering curve. Generally, there should be a heating process, a high-temperature densification process and a cooling process. All three processes are very important to the quality of ceramics. The heating process takes about 15 ~ 2 hours to ensure that cracks will not occur. Generally, the high temperature process takes 2 ~ 4 hours, and the temperature drop takes 1 ~ 15 hours.
