Identify a piece of china by its pattern by first identifying the name of the pattern and the brand of the china. If the china has only the logo of a manufacturer, research the logo online to identify the specific china and order replacements if necessary. Another option is to ask a store or individual to identify the piece of china.
It may be possible to identify newer china sets by turning the item over and searching for both the manufacturer name and the pattern name. This, along with other possible information on the plate such as the country of origin and the date of manufacturer, can help fully identify this china.
Certain pieces of china may not have readily available information. Search the entire set because a logo may be on another piece such as a serving piece or dinner plate. It may be necessary to research the logos of different china manufacturers because many of them have used different logos throughout the years, making identification difficult.
Once a manufacturer has been identified, use websites such as Replacements.com to browse different patterns by manufacturer name and see what matches the china in question. If the above methods do not work, consult with a specialty shop or vendor in order to identify the china.
