How do I date an old glass jug?

Dating relies upon examining pontil marks, handle application styles and the overall colour palette of the metal. Georgian pieces often display distinct pontil scars and heavier proportions. Later Victorian and Mid-Century Modern examples introduce brighter chemical colourations and cleaner base finishes. Comparing the form to documented regional styles helps confirm the period.
