How can I date Minton porcelain without a receipt or box?

Dating usually starts with the backstamp style, then moves to the design, form, and manufacturing clues. Compare your mark with documented examples from reliable references, then look at decoration cues, such as Victorian gilding and heavy ornament feel different from mid-1900s tableware patterns. Shape matters too, as factories introduced new blanks over time, and certain profiles suit specific periods. For a better estimate, cross-reference any pattern number, registry marks (if present), or named patterns that have known start dates.
